2. SingleRAN Solution Highlights Summary

Huawei‟s SingleRAN solution is an industry first, unique convergent solution for operators who

run more than one network, especially for GSM/UMTS multi-mode network. It is a series of

future-oriented and convergent network solutions (such as Multi-mode BSC, SingleBTS, IP

RAN, GSM/UMTS inter-working algorithm, etc.) in relation to network architecture,

transmission, facilities and O&M system. SingleRAN makes the technology choices and

network evolution simple and greatly reduce access to the site, the equipment room building,

transmission and other ancillary costs of the OPEX.

Huawei‟s SingleRAN solution embraces three essential elements (Uni-equipment, Uni-site

and Uni-operation):

Figure 1 Key Figures of SingleRAN

Uni-equipment: “One Network” Guarantee Flexible Evolution & Investment Protection

SingleBTS: SingleBTS (also known as 2G/3G integrated SingleBTS) makes Uni-site

(Co-transmission & Co-auxiliary facilities) a reality. The modular and multi-mode design of Huawei‟s

SingleBTS, supporting 2G and 3G in one compact cabinet, presents the ultimate solution. With its

integrated SDR and MCPA technologies (software defined radio and multiple carrier power

amplifiers), the SingleBTS also supports software upgrades from GSM to UMTS on a single module

– protecting operators‟ earlier investments in existing GSM equipment and sharply reducing the time

of UMTS deployment.





Figure 2 Huawei SingleRAN BTS Expansion and Evolution

MBSC: MBSC (also known as integrated BSC/RNC) makes Uni-Operation a reality. Huawei‟s solution

provides the integration of GSM BSC and UMTS RNC into a multi-mode BSC (MBSC). MBSC is

designed with the unified PARC platform, which can support 2G and 3G in the same cabinet and provide

IP/TDM dual-switching plane. 2G and 3G can share many boards in MBSC, thus it saves a lot in spare

management.

Furthermore, SingleRAN solution is compatible with technologies evolution to guarantee long term viability.

All of its products are ready to evolve to LTE system.

Figure 3 MBSC or Integrated BSC/RNC

Uni-site: “One Deployment” Bring TCO Saving

Co-Transmission With Huawei‟s multi-mode BSC and the SingleBTS, transmission sharing is

achievable within the system and allows future service convergence. The value of Huawei‟s dual





stack transmission mechanism for ATM and IP, and hybrid transmission and clock synchronization

over IP, translates into ultimately smooth and flexible network evolution.

Figure 4 Co-Transmission Reduces Transmission Cost

Co-Auxiliary Facilities With SingleBTS, operators deploy multi-mode networks by one time and

both GSM and UMTS networks can share the same facilities, such as cabinet, antenna system,

feeder system, power system, battery and etc.

Figure 5 Reuse Antenna System

With one time deployment, operators can now reduce not only cost (footprint saving brings less lend

cost, one time deployment brings less engineering cost), but also the time previously spent on

construction and deployment.

Uni-operation: “One Team” Improve Network Performance and Maintenance Efficiency

Co-OAM (operation and maintenance) combines all operations on one platform to facilitate network

operation and maintenance most. By one team, human resources efficiency is largely optimized.

Around 30-40% cost can be saved in NOC and field operation, spare parts management and

network performance optimization by incorporative operation.





Figure 6 Co-OAM

Co-RNP/RNO (Radio network planning & optimization) allows constant 2G/3G network

performance monitoring for further analysis. Project sharing, joint parameter management and

common tools are used for multi-mode network planning and optimization (coverage, capability, and

neighboring cell) to realize high quality of “one network”.

Figure 7 Co-RNP/RNO

With Co-RRM (Radio Resource Management) RNC and BSC are unified as one network element

and Co-RRM function is core network- independent. Co-RRM auto-allocates radio resources

between 2G and 3G networks based on service and load. Data service throughput improves by as

much as 25%. SingleRAN solution dynamically allocates radio resources to ensure the most optimal

usage, which results in 10% handover.

Figure 8 Co-RRM





With Co-TRM (Transmission Resource Management), transmission sharing can be implemented

for both voice and data services, guaranteeing QoS and improving transmission efficiency up to

10%.

Figure 9 Co-TRM

Huawei‟s pioneering SingleRAN solution can support GSM/UMTS/LTE simultaneously, which will

help the operator to realize one network for multi-mode, and a single OMC can support the

management of multi-mode networks. All these features can facilitate our customer in great amount

to cut off their TCO drastically. Allowing operators a first-time opportunity of truly deriving those

ultimate benefits, Huawei‟s SingleRAN solution will help operators establish a “maintenance-easy”

infrastructure so that operators can focus on market. With an enhanced single service platform,

quality of service can be maintained, new applications quickly introduced, and ARPU increased, and

competitive strengths enhanced. Huawei‟s SingleRAN truly affords our expanding wireless world a

viable solution that is “One For All.”

High Performance HSPA+ for Mobile Broadband

a) HSPA+ Phase 1 solution supports 21Mbps and 28Mbps in downlink with 64QAM and 2x2

MIMO respectively. HSPA+ Phase 1 can be evolved to HSPA+ Phase 2 smoothly.

b) Huawei RAN12 includes a new series of important functions concerning the improvement in

HSPA+ data throughput, these features include Dual Cell-HSDPA (DC-HSDPA), DL

64QAM+MIMO and UL 16QAM introduction.

c) HSPA+ Phase 2 solution supports 42Mbps in downlink with combination of 64QAM and 2x2

MIMO or DC-HSDPA. And in uplink HSPA+ Phase 2 solution supports 11.5Mbps with uplink

16QAM.

d) For HSPA+ commercial application, Huawei is the leading vendor now. By Q4 2010, Huawei

had already won more than 48 commercial HSPA+ contracts (market share 46%).

e) Huawei HSPA+ Solution help VDF provide best coverage and break every speed record in

Greece.





Figure 10 Best coverage in VDF Greece with Huawei HSPA+

Figure 11 High Speed performance in VDF Greece with Huawei HSPA+

Field Proven industry leading IP solution

a) Huawei is the 1st vendor to provide native IPRAN solution instead of pseudo wire technology

since 2006Q4, which is 2 years ahead of other vendors‟.

b) Clock over IP is utilized in Huawei IPRAN solution to get synchronization without external GPS

or E1. Innovative IP clock solution saves GPS investment.

c) Customized IP solution based on existing transmission topology that provide the maximum

investment protection. Huawei could provide IP over ATM solution, Hybrid ATM/IP solution,

and All IP solution.

d) Hardware ready for IP transmission avoids upgrade cost dramatically (Hardware are ready

with IP-based integration to avoid massive upgrade cost).

e) Abundant experience in IP solution helps to minimize the risk of evolution to all-IP network.

Huawei is the 1st vendor to provide native IPRAN solution instead of pseudo wire technology

since 2006Q4, which is 2 years ahead of other vendors‟. Huawei IPRAN has been deployed in

commercial UMTS networks by mobile operators such as Etisalat in UAE, eMobile in Japan,

Etisalat in Egypt, and StarHub in Singapore. And it also passed the stringent tests performed

by operators such as Vodafone, Spain; France-Telecom Orange, France; TI, Italy, etc.

Huawei unique MIMO solution: 2 years ahead industry for hardware ready

a) Huawei is the only Vendor to support MIMO DBS, achieving up to 85% gain in performance.

b) Huawei unique Co-Carrier MIMO solution helps to improve more than 20% cell throughput.

c) MIMO brings negative gain to legacy UE when MIMO and HSPA co-carrier, Huawei is the only

one vendor can minimize the impact.





Green for Energy Conservation and Emission Reduction

a) Huawei NodeB features lowest power consumption (400W@S1/1/1) in the industry with

advanced power amplifier technology (DPD+A-Doherty) and excellent engineering design.

b) Based on energy-efficiency-improvement technologies of both Node B and its site facility, it is

possible to utilize the reproducible energy such as wind or solar energy.

c) With innovative DNBS solution, operators can achieve green delivery of easier site acquisition,

easier civil work, easier delivery, etc.

Innovative SingleRAN for TCO Saving and Smooth Migration

a) MSR based SingleRAN enables flexible evolution among GSM/UMTS/LTE on the same

frequency, especially for UMTS900&GSM900, GSM1800&LTE1800 in same RRU, thus avoid

huge reduplicate investment and ensure smooth evolution for 900MHz/1800MHz radio

frequency resource.

b) Industry leading 6-carrier technology enable once for all hardware deployment, thus minimize

the OPEX cost due to future expansion.

c) The BBU hardware is ready for HSPA+ phase 2 (Combination of downlink 64QAM and MIMO

2 x 2 or DC-HSDPA) upgrade and can be further upgraded to HSPA+ phase 3 with additional

new baseband card and LTE respectively, thus make the upgrade much easier.

d) Dual Mode RNC and BSC enable simplified network architecture, less number of BSC and

RNC. Based on Dual Mode RNC&BSC, Co-TRM with higher transmission efficiency saves

huge amount of transmission resources, Co-RRM can balance the traffic between GSM and

UMTS intelligently, and then switch off the idle carriers to save power consumption. Co-OAM

with higher human resources efficiency brings OPEX saving.

3. Network Proposal for VMS

3.1 Requirement Analysis

3.1.1 Summary of Requirement

As one of the top three major mobile communication operators in Vietnam, VMS is

facing fierce competition and long-term challenge in the matured 2G mobile market.

Undoubtedly, introduction to 3G is able to stimulate service to keep VMS in the leading

position. However, with the coexistence of multiple network technologies, it demands

VMS to construct separate networks leading to increased OPEX and CAPEX. In this

proposal, Huawei offers SingleRAN solution which can integrate the functions of the

GSM and UMTS, and provide the highest capacity with the smallest footprint in the

market. It is also able to enhance the service coverage and to meet increasing mobile

broadband demand in Vietnam. With one purchase decision, VMS can now realize the

optimal benefits of ownership from a cost and time efficient solution for multiple network

investment protection, enhanced performance, reduced OPEX and CAPEX, and

improved TCO.

Huawei has been the supplier in Vietnam telecommunications market for more than

nine years, which is one of the experienced players in the telecommunication to promise

innovative technologies and cost-effective solutions. Based on Huawei‟s understanding

of Vietnam market, studying the requirement documents and VMS‟s network

environments, Huawei is convinced to have ability to fulfill VMS requirements in such

aspects as below:

Construct a 2G/3G SingleRAN system including 2G/3G integrated SingleBTS

equipment, BSC/RNC equipment and uniform OMC system for VMS Center I

and V.

Maximum output static power of each GSM TRX measured at the top of cabinet

(TOC) must be at least 20W; Maximum output static power of each UMTS carrier

measured at the top of cabinet (TOC) must be at least 20W.

The proposed 2G/3G integrated SingleBTS is configured with singleband

GSM900 S4/4/4 or dualband GSM900 S2/2/2 + GSM1800 S2/2/2 or distributed

GSM900 S4/4/4, and distributed WCDMA S2/2/2 (Band 2100M, 384CE UL/

384CE DL, HSDPA+ 21Mbps per cell, HSUPA 5.76Mbps per cell).

Fast deploy a complete GSM/UMTS network, save time-to-market, to gain

competitive edge in Vietnam market by cooperating with vendor who have strong

local presence and hold a good track record of accomplishment in Vietnam.

The proposed SingleRAN equipment is hardware ready for IP RAN to realize

All-IP solution in near future.

Offered network elements for this northern region include 1160 2G/3G integrated

SingleBTSs (570 for Center I and 590 for Center V), 11 integrated BSC/RNCs (5

for Center I and 6 for Center V), 2 OMC-R (1 OMC-R for each Center I and V),





230 sets of additional materials for split and re-installation (200 sets for Center I

and 30 sets for Center V), 33 Transport Nodes for supporting transmission

between NodeB and RNC (15 for Center I and 18 for Center V), 2 sets of

Management System for Transport Nodes (1 Transport Node Management

System for each Center I and V), and related installation accessories.

The proposed network flexibly and smoothly evolves to HSPA+ supporting

downlink of 21 Mbps, HSPA+ Phase 2 supporting downlink of 42 Mbps and LTE

system in future.

3.1.2 Subscriber Distribution

From VMS‟s 2G subscriber number requirement, the total subscriber number for

Center I is given as 2.3 Million while the total subscriber number for Center V is given

as 2.2 Million. Therefore the northern region (Center I and Center V) has total

subscriber number of 4.5 Million.

However, in order to meet VMS‟s minimum requirement of 2048 TRXs as well as the

30% capacity redundancy, the maximum total subscriber for 5 BSC in Center I is

dimensioned and supported up to 2.88 million (subs) while the maximum total

subscriber for 6 BSC in Center V is dimensioned and supported up to 3.45 million

(subs). Therefore, the total subscriber number for the northern region (total 11 BSCs

for Center I and V) is approximately 6.33 million subscribers where is much higher

than the given total subscriber for the Northern region..

For 3G, the total subscribers number given in Center I is 2 million (sub) while the total

subscribers number given in Center V is 1.8 million (sub) respectively based on the

VMS‟s requirement. From the details obtained from VMS‟s RFP requirement, there are

total 11 integrated BSC/RNC in Center I and Center V which is 5 integrated BSC/RNC

for Center I and 6 integrated BSC/RNC for Center V. By assigning the total subscriber

number evenly in each integrated BSC/RNC for Center I and Center V, the subscriber

number is equals to 400,000 (3G sub) for Center I and 300,000 (3G sub) for Center V.

Furthermore, the VMS‟s minimum requirements of 3Gbps total throughput, at least 300

NodeBs/900 Cells as well as the 35% capacity redundancy for each integrated

BSC/RNC are fulfilled.

3.2 Construction Strategy

Taking into account the challenges VMS faces in the Vietnam market, Huawei would

like to present the following compelling business propositions which are able to deliver

the best business values to VMS:

Adopt 2G/3G integrated SingleBTS equipment (also known as SingleBTS) that is

able to support SDR (Software Defined Radio). Its RF module can migrate from

GSM to UMTS and then to LTE in 900MHz GSM frequency band, from GSM to

LTE in 1800MHz GSM frequency band, and from UMTS to LTE in 2100MHz

UMTS frequency band only by software upgrade without any radio hardware

replacement. It allows flexible configuration between 2G and 3G and can be

smoothly evolved to LTE.

Propose Huawei MRFU with total 80W output power supports 6 TRX/MRFU in

GSM only and 4 carriers/MRFU in UMTS only and flexible configuration between

GSM and UMTS. It supports static 20W TOC power in case of S4 configuration

due to total 80W output power per MRFU for one cell for SingleBTS 2G RF. For

SingleBTS 3G RF, it supports 20W power in case of S3 configuration due to total

60W output power per RRU3804 for one cell.

Adopt SingleBTS that is based on new technologies including MCPA design and

DPD and Doherty technology both in 2G and 3G parts to enhance PA efficiency

to 40% both in 2G and 3G part. It also supports maximum 6TRX per 2G MRFU

unit and 4 carriers per 3G 3804 unit so that can support future expansion to

12/12/12 GSM (6/6/6 GSM900 + 6/6/6 GSM1800) and 3/3/3 UMTS configuration.

Besides, the proposed SingleBTS 3G NodeB supports 384/384(DL/UL) CE both

in hardware and software license.

All of Huawei‟s SingleBTS offered to VMS GSM/UMTS network support full

performance EDGE, HSDPA and HSUPA before CLR (Commercial Launch

Ready) to meet VMS‟s mobile broadband requirements. It supports HSPA+ with

the maximum peak rate up to DL 21 Mbps / UL 5.76 Mbps per cell and supports

HSPA+ Phase 2 (DL 42Mbps / UL 11Mbps) through upgrading.

Propose interface of TDM/E1, ATM/E1 and IP/FE and GE solution for SingleBTS.

In addition to TDM/E1 synchronization solution, IP Clock (1588V2)

synchronization solution is proposed for SingleBTS to get clock signaling from

VMS‟s ME+ network.

Deploy distributed DBS that could save more than 30% of Total Cost of

Ownership (TCO) including cost of site location, equipment installing, power

consumption, TMA, maintenance etc. Huawei‟s DBS3900 includes two parts,

BBU and RRU. With different integrated methods of BBU and RRU, Distributed

BTS can fit for different application scenarios.

2G/3G Smooth Evolution – The 3G and IP based design can ensure the GSM

system evolves to the 3G system easily. For instance, Huawei BSC shares the





same hardware platform with Huawei RNC. VMS can upgrade from BSC to RNC

according to capacity requirements flexibly and smoothly. The 2G BTS can also

support 2G/3G co-cabinet (or 2G/3G dual mode). TDM/IP Co-transmission,

Co-OM, Co-RNP/RNO, Co-RRM, Future proof design to protect VMS initial

investment.

Deploy large capacity integrated BSC/RNC (also known as MBSC) to decrease

the number of network elements, simplify network topology, allows easy

maintenance that result in reduced OPEX. Its high packet throughput can fully

meet the traffic requirements of EDGE/HSDPA/HSUPA. It can support up to 4096

TRX per BSC (PCU embedded) with standalone TC, and up to 12Gbps per RNC.

Propose three kinds of power supply to meet the power requirement for different

equipment individually including indoor and outdoor BTS, BSC, TC and

Transporting Node. The proposed battery and power systems are based on the

maximum load design with N+1 redundancy in rectifier module and 6 hours

backup time in battery.

Adopt large capacity for OMC-R by offering one OMC-R for each center. It can

manage 2G/3G simultaneously and support all IP connections.

Deploy OSN7500 at hub-site transport node and OSN7500+NE40E at RNC-site

transport node. OSN7500 is offered as the SDH layer equipment, and NE40E is

offered as packet layer equipment.

Huawei hopes that the above principles are suitable and beneficial for VMS project.

Huawei looks forward to working closely with VMS to generate the final solution that

concur with the requirements specified.

Each BSC is dimensioned with STM-1 and optical GE interfaces for interconnection with

2G BTSs. Each RNC is dimensioned with STM-1 and optical GE interfaces for

interconnection with 3G NodeBs.

Considering that the BSC and RNC need to inter-work with the existing Core

Network equipment from other vendors, A interface is designed with FE interface,

and IuCS interface is designed with both STM-1 and GE interface, and Gb interface

is designed with both optical FE and E1, and IuPS interface is designed with both

optical GE and STM-1 interface for VMS flexible deployment.

3.3.1.3 OMC-R and PRS server

order to manage all the integrated BSC/RNC. One O&M terminal and one alarm

terminal are configured in the central room and remote room respectively.

3.3.1.4 GTCS (Transcoder)

Based on the requirement, TC is not embedded inside the BSC model, thus Huawei

proposes standalone TC for each BSC, with total of 5 TCs for Center I and another 6

TCs for Center V. Besides, Huawei also proposes STM-1 for Ater interface and A

interface to meet VMS‟s requirement for the transmission purpose.

3.3.1.5 IP Clock Server

In order to achieve IP clock synchronization from integrated BSC/RNC side to 2G/3G

integrated SingleBTS, two IP clock servers co-locating with the integrated BSC/RNC





equipment are offered in this proposal. Each IP clock server is for BSC and RNC

respectively. One IP clock server is configured for each BSC and RNC respectively.

feeder type required which includes 7/8 feeder and 1/2 feeder and other related

accessories have been proposed.

3.3.2 Proposed Transmission Network

For transmission network design, Huawei proposes OSN7500 as the Hub-sites

transport Node and OSN7500+NE40E as the RNC-site transport nodes.

In Hub-sites, OSN7500 will connect all the PDH and Ethernet service and

convergence to STM-1, GE or 10GE services.

In RNC-sites, OSN7500 will work as the SDH layer equipment to process all the PDH

and SDH services. And NE40E will work as the packet layer equipment to process all

the Ethernet services and provide L3 and IP routing functions.

All the OSN7500 and NE40E will be managed by iManager U2000 system, each

center of VMS will have one to manage the transmission node independently.

3.3.4.3 Proposed 2G/3G integrated SingleBTS Equipment

There are 3 types of models for 2G/3G integrated SingleBTS: For Macro Indoor GSM

and Distributed WCDMA, Huawei proposes BTS3900 + DBS3900. For Macro Outdoor

GSM and Distributed WCDMA, Huawei proposes BTS3900A + DBS3900. For

Distributed GSM and Distributed WCDMA, Huawei proposes DBS3900 + DBS3900

With Distributed GSM and Distributed WCDMA, VMS can efficiently deploy a

high-performance 3G network with a low TCO since The baseband processing unit

(BBU) of DBS3900 is characterized by a small footprint, easy installation, and low

power consumption. In addition, the BBU can be installed in the spare space of an

existing site. The remote radio unit (RRU) of DBS3900 also has a compact design and

light weight, and it can be installed close to the antenna to decrease feeder loss and

improve system coverage performance.

Macro Indoor/Outdoor GSM is for compact installation with smaller footprint, fewer

module types, G/U co-cabinet capability and excellent expandability.

3.3.4.4 Proposed IP Clock Server Equipment

For IP clock server, Huawei proposes IPCLK1000. It uses the same service data

transmission protocols as those for data transmission between the integrated

BSC/RNC and the BTS/NodeB. While the integrated BSC/RNC and BTS/NodeB have

embedded the function of IP Clock client, therefore, the introduction of IPCLK1000 has

no additional requirements for topologies or for Qos performance of networks. Besides,

it can be installed alone, in an integrated BSC/RNC cabinet or any other cabinet that is

300 mm in depth. In this proposal, Huawei provides one IP clock server for BSC and

3.4.5 Offered 2G/3G Integrated SingleBTS RF Connection with Feeder and Antenna

The following diagram shows the RF part of interconnection between Macro/ Distributed

2G/3G integrated SingleBTS, antenna and feeder system.

Considering Huawei‟s RFU/RRU can support 6 TRXs or 4 Carriers with just one unit of

hardware, so the RF connection is very convenient, just one RF unit for one sector is enough,

whatever regardless it is the Outdoor Macro BTS (BTS3900A), Indoor Macro BTS (BTS3900),

Distributed BTS (DBS3900) or the Distributed NodeB (DBS3900).

The number and model of all equipment using for RF connection are shown in the

following table (duplexer, diplexer, combiner, antenna…).

With Huawei advanced RF design, the function of the duplexer and multi-carrier power

amplifier have been implemented in the RF unit, so there is no external duplexer or

combiner are needed, only the jumper and feeder are needed to connect with antenna.

The proposed network topology and dimensioning results (throughput and physical

ports) are given, for SingleRAN and OMC respectively, in the following sections.

4.1 SingleRAN Network Dimensioning

4.1.1 BSC Model Dimensioning

There are 5 BSC offered for 570 sites in Center I and 6 BSC offered for 590 sites in

Center V. According to VMS‟s requirement, Huawei RNP plans the site/TRX distribution

as below:

BSC 5 129 1534 2048 2048

BSC 6 129 1534 2048 2048

Refer to the Table 51 and Table 52 as above:

In Center I, with 30% redundancy, the TRX number calculated for each BSC model

= 1368 * (100% + 30%) = 1779 TRX.

In Center V, with 30% redundancy, the TRX number calculated for each BSC

model = 1180 * (100% + 30%) = 1534 TRX.

As stated in the tender document, the minimum configuration for each BSC is to

support 2048 TRXs.

Since the TRX number for each BSC in Center I and Center V is still less than the

minimum TRX requirement from VMS after considering the 30% redundancy, therefore,

the TRX number is dimensioned and designed as 2048 TRXs for each BSC in Center I

and Center V.

4.1.1.1 Center I

The following shows the formulae for the BSC model throughput in Center I.

A-CIC Channel = ErlangB_Device (A-Erlang, A GOS)

A-Erlang = ErlangB (average TCH-PDCH)*(1+HR ratio), Abis GOS)*3*BTS

number*A:Um ratio*Index ratio.

PDCH Channel= (Static PDCH / Cell +Dynamic PDCH / Cell *Dynamic PDCH Active

ratio) * BTS Cell number

Gb throughput = subs*throughput per user/1024/1024/Gb utilization ratio

Based on the mentioned formula above, the calculation result shown in the table below;

The detailed calculation (2048 TRXs/BSC) is shown as below;

A-Erlang = ErlangB((average TCH-PDCH)*(1+HR ratio), Abis GOS)*3*BTS


Taking HR ratio: 30%; Um GOS / Abis GOS: 1% / 3%, A:Um ratio: 80%, BTS Qty: 114

So, A-Erlang = 43.85 * 3 * 114 * 80% * (5.9883/6) = 11,975 Erl

A CIC Channel = ErlangB_Device (A Erlang, A GOS)

The active percentage of the GPRS is assumed to be 10%

GPRS Subs = Total Erl / Average voice traffic per subscriber (Erlang) * 10%

is shown as below (all the interface ports comply with active and standby redundancy

configuration).

The following shows the formulae for the BSC model throughput in Center V.

A-CIC Channel = ErlangB_Device (A-Erlang, A GOS)

A-Erlang = ErlangB (average TCH-PDCH)*(1+HR ratio), Abis GOS)*3*BTS

Taking HR ratio: 30%; Um GOS / Abis GOS: 1% / 3%, A:Um ratio: 80%, BTS Qty: 99

Considering 35% throughput redundancy requirement and minimum 300 NodeBs

RNC 5 134 797 300 900

RNC 6 134 797 300 900

Refer to the Table 59 and Table 60:

In Center I, with 35% redundancy,

Total site number for each RNC = 114 * (100%+35%) = 154 sites

Total cell number for each RNC = 684 * (100%+35%) = 924 cells

In Center V, with 35% redundancy,

Total site number for each RNC = 99 * (100%+35%) = 134 sites

Total cell number for each RNC = 590 * (100%+35%) = 797 cells

As stated in the tender document, the minimum configuration for each RNC is to support

300 sites/900 cells, therefore, each RNC in Center I is dimensioned and designed with

300 sites/924 cells while each RNC in Center V is dimensioned and designed with 300

sites/900 cells. On the other hand, the minimum requirement for the RNC throughput is

at least support up to 3Gbps capacity throughput, however, this throughput requirement

cannot be met if the traffic parameter of PS throughput per sub is 152 bps.

So, in order to meet the minimum requirement as mentioned as above, the traffic model

for Center I and Center V are designed and dimensioned accordingly in adjusting the PS





throughput per PS subscriber in Busy Hour (bps) to 2000 bps with the given total

subscribers number per integrated BSC/RNC based on Huawei‟s RNP calculation.

4.1.2.1 Center I

By optimizing the PS throughput per PS subscriber in Busy Hour to 2000 bps, the total

throughput is resulted to 1178.4 Mbps for each integrated BSC/RNC in Center I. The

following table shows that the total throughput resulted with the optimized traffic model in

Center I.

However, the total throughput obtained to be 1178.4 Mbps cannot meet VMS‟s total

throughput requirement of 3Gbps. Therefore, by remaining the total subscriber number

and CS Erlang throughput, PS throughput need to be increased to 2032 Mbps by

adding UMTS Data Processing Unit and Hardware License.

4.3 OMC & PRS Network Dimensioning

For this proposal, one OMC-R server type is configured as shown in the following table.

Table 81 Offered OMC-R System Server Type

Server Hardware Maximum Management Capacity

Sun M5000 Single Server

SUN M5000 (4CPU) maximum supports 190 essential NE.

50 Cells equals 1 essential NE for WCDMA and 125 TRXs equals to 1 essential

NE for GSM.

Since the offered OMC-R server hardware can support up to 190 equivalent NEs, the

maximum number of cells can be derived as the following:

Maximum number of cells for RNC+Node B

= 190 equivalent NEs x 50 cells/1 equivalent NE

= 9,500 cells

Maximum number of TRXs for BSC+BTS

= 190 equivalent NEs x 125 TRXs/1 equivalent NE

= 23,750 TRX

For northern region (Center I and V), the actual site number and cell number with 35%

redundancy are shown as below:

redundancy as shown as below:

Center I 570 6840 741 8892

Center V 590 7080 767 9204





Also considering the minimum requirement of the OMC capacity from VMS (the

hardware of each OMC system must be dimensioned for supporting up to 10000

TRXs/5000 cells), the cell number for Center I is increased from 4,617 to 5,000 and the

cell number for Center V is increased from 4,779 to 5,000. For the TRX dimensioning

part, the TRX number for Center I is increased from 8,892 to 10,000 TRXs and the TRX

number for Center V is increased from 9,204 to 10,000 TRXs. The final dimensioning

result of OMC-R capacity requirement for Center I and V are listed as below:

Center I 741 10000

On top of above dimensioning principle, the total cells numbers and total TRXs numbers

of each OMC-R is 5000 Cells/10000 TRXs for Center I and 5000 Cells/10000 TRXs for

Center V, thus the total essential NEs of each OMC-R can be calculated in the following

formula: (Total Cells number / 50 Cells + Total TRXs number /125 TRX), where the total

essential NEs is 180 for both Center I and Center V, which is smaller than 190, so the

type of M5000 with 4CPU can support the particular capacity requirements, because it

is hardware ready to support 9500 cells/23750 TRXs and 190 essential NEs.

For the PRS server dimensioning, the iManager server module proposed is HP DL785

where can cover on the large sized networks, where the supported equivalent NE is less

or equal to 800 NEs.

In Center I & V, the OMC-R system is configured on 5000 TRXs/10000 Cells,

Total essential NEs in PRS = 5000/62.5 + 10000/125 = 160 NE

Since the offered PRS server hardware can support up to 800 equivalent NEs, the

maximum number of cells can be derived as the following:

Maximum number of cells

= 800 equivalent NEs x 62.5 cells/1 equivalent NE

= 50,000 cells

Maximum number of TRXs

= 800 equivalent NEs x 125 TRXs/1 equivalent NE

= 100,000 TRX

5. Highlight of Huawei SingleRAN Solutions

5.1 SingleRAN Product Overview

5.1.1 Multi-mode BSC

Figure 27 Multi-mode BSC

Inherit unified platform

Huawei‟ multi-mode BSC6900 is based on self-developed PARC (Platform of Advanced

Radio Controller) platform with IP/TDM dual-switching plane and high reliability. Because of

Huawei‟s durative R&D strategy, legacy BSC (BSC6000 for GSM&BSC6810 for UMTS) can

be upgraded to BSC6900.

First-in-class capacity and density

BSC6900 has a First-in-class capacity (5100Cells and 12Gbps throughput for UMTS

only/4096TRXs for GSM only) in industry. BSC6900 has only 7 board types (excluded

interface board), it saves a lot in spare management. This large capacity and multi-mode

BSC not only provide a more flexible solution, but also meet the needs for the wireless

broadband, which greatly protect our customer‟s investment and being ready for the future

technologies.

TCO saving

The combined multi-mode BSC causes simple network architecture, less number of BSC is

needed. Co-TRM with higher transmission efficiency saves huge amount of transmission

resources, Co-RRM can balance the traffic between GSM and UMTS intelligently, and then

switch off the idle carriers to save power consumption. Co-OAM with higher human

resources efficiency brings OPEX saving.

Multimode brings flexible configuration and uni-operation

To meet different networking requirements, BSC6900 can support GSM only or UMTS only

or GSM/UMTS in same cabinet; share the same sub-rack and the same boards. The

capacity of each mode can be transferred dynamically according to the trend of

traffic.BSC6900 is a milestone of Multi-mode BSC, it supports Co-TRM, Co-RRM, Co-OAM,





Co-RNP, all these features benefits operators with not only TCO saving but also better

network performance.

Improve network performance through optimized Co-RRM algorithm

The Co-Radio Resource Management (Co-RRM) algorithm performs unified management

and intelligent scheduling on the radio resources in the GSM network and UMTS network.

As the traditional Co-RRM algorithm exchanges the 2G/3G load information between the

GSM network and the UMTS network through signaling procedures across the core

networks (CNs). The BSC6900 optimized Co-RRM algorithm enables rapid transmission of

2G/3G load information (used as internal messages) with an internal procedure. The

advantages are as follows:

Having no dependency on the equipment in the core network

Reducing latency, adjusting the load in real time, and increasing the success rate of

inter-RAT handovers

Decreasing the signaling flow on the standard interface and saving interface resources

The optimized Co-RRM algorithm maximizes the sharing of radio resources between the

GSM network and the UMTS network, thus increasing the network capacity.

5.1.2 SingleBTS Introduction

Convergence

Figure 28 Module design BTS

Huawei SingleBTS 3900 series are based on self-developed platform HERT and adopt modular

design. The 3900 series BTS include 3 parts, RRU (Remote Radio Unit)/RFU (Radio Frequency

Unit)/BBU (Base Band Unit), which can be combined in different ways in order to adapt various

scenarios. Modular design also simplifies the transportation, installation, maintenance of the BTS

and the most significant is that the SingleBTS can support GSM/UMTS/LTE simultaneously.





Figure 29 The SingleBTS Portfolio

To come across various capacity and coverage requirements of operator, Huawei delivers a

comprehensive BTS family that includes the Macro BTS, Distributed BTS, Micro BTS, etc to

achieve seamless coverage. It is convergent platform between different BTS portfolio as well as

convergent platform between GSM, UMTS and LTE.

Evolution

Figure 30 Huawei convergent BTS expansion and evolution

Cabinet based macro indoor BTS (BTS3900) and outdoor BTS (BTS3900A) is suitable for

centralized installation as well as G/U multi-mode and multi-band scenarios. It can support

72TRXs for GSM or 24 cells for UMTS in all.

The 3900 series multi-mode base stations provide multiple evolution solutions and support the

evolution from GSM to UMTS and further to LTE. BBU can be reused when evolve to UMTS or

LTE, only need to insert relative two sub-boards into BBU: WMPT or LMPT for control and

transmission, WBBP or LBBP for baseband processing.

Application of the SDR technology





With the SDR technology, RF modules can support any type of dual-mode among GSM, UMTS,

and LTE in the same frequency through software update, so to meet operator‟s requirements that

need fast and one-time deployment.

Co-cabinet solution

RF modules serving different modes (includes SDR module) can be installed in the same cabinet

so that the single-mode or any type of dual-mode among GSM, UMTS, and LTE is applicable to

the base station. RF modules operating in different frequency bands can also be housed in the

same cabinet. In this way, the multi-mode and multi-band application is available.

Green

Stackable design makes it possible for hand carry installation and flexible expansion. The macro

outdoor BTS (BTS3900A) can work stably in the range of -40 to +50 degree Celsius. Air

direct-ventilation design makes it more reliable without air condition or heat-exchanger for

temperature adjustment. It has the same baseband and radio performance with indoor macro

BTS.

Distributed BTS (DBS3900) separates traditional cabinet BTS into two parts, baseband unit (BBU)

and remote radio unit (RRU). RRU can be mounted near the antenna to save feeder loss of 3 dB

and TMA (Tower Mounted Amplifier). They mark small size, large capacity and high integration.

Therefore, we can provide a zero footprint solution thus fulfilling the desire of easier, faster site

acquisition, installation and network deployment.

Huawei SingleBTS can support multiplicate methods on power control, there are two main kinds:

1. dynamically shut down idle resources, like cell, TRX and PSU boards, 2. allocate accurate

power according to actual traffic requirement, like BCCH power optimization and power

optimization based on channel type. Based on these advanced and innovative power control

technologies, Huawei SingleBTS can bring extra 10-25% power consumption saving.

High effective digital power amplifier (DPA) saves the electrical power cost. With DPD+ A-Doherty

technology, the PA efficiency is up to 40%. DBS3900 S111 typical power consumption is only

400W compared to the traditional common Node B of 1500W.

Figure 31 Power consumption cooperation





5.2 Multi-mode Solutions

With the development of UMTS, more and more traditional GSM operators migrated to the

UMTS network in order to provide high speed data service and carry superior service

experience. Based on UMTS network, operators are able to launch more abundant and

differentiated services to end users, and attract more subscribers. Meanwhile, UMTS

network helps operators improve the ARPU and MOU, and keep leading in the market.

With the evolution of GSM network to EDGE all over the world, GSM/EDGE and UMTS will

co-exist for a long time, the inter-working and traffic balance between GSM/EDGE and

UMTS is still significant

For mobile operators, balancing the investment between GSM and UMTS and acquire most

profit in GSM/UMTS deployment is becoming more important.

Based on all theses requirements of our customer, Huawei would provide different

multi-mode solutions to meet different needs in typical scenarios.

Figure 32 High Expansibility BBU3900

Thanks to Huawei‟s unified HERT platform, baseband module, BBU3900 can be applied in

GSM or UMTS mode by plugging in different daughter card. Meanwhile, baseband and

transmission can be expanded separately. It also can be smoothly evolved to LTE by adding

LTE baseband daughter card. Different combination of RF module and BBU3900 realize two

multi-mode solutions: Co-cabinet solution and SDR solution.

5.2.1 Co-cabinet solution for multi-mode

In order to meet the requirement of operators‟ GSM/UMTS deployment, Huawei presents

multi-mode BTS solution, which is applicable for GSM/UMTS multi-mode deployment and

capable of smooth evolution from EDGE to HSPA to HSPA+ to LTE.

Huawei‟s multi-mode BTS solution supports cabinet-based multi-mode and distributed

multi-mode.

Cabinet-based multi-mode BTS: BTS3900 and BTS3900A.





The cabinet-based multi-mode application has minimized footprint by sharing common G/U

platform and using different G/U RF module. The stackable cabinet is easy to hand carry to site,

and it makes expansion more flexible. Cabinet-based multi-mode BTS is capable of evolution to

LTE.

Indoor BTS3900

Figure 33 Compact GSM/UMTS Multi-mode indoor BTS

BBU (Base Band Unit) can be shared by GSM and UMTS and inserted into the 2U space

reserved in the BTS cabinet. GSM, UMTS and LTE radio units are inter-changeable. The

stackable cabinet, easy for transportation and installation, only need 1 cabinet footprint, 100%

reuse site facilities: minimum investment on power, battery, feeder and antenna.

Outdoor BTS3900A

Figure 34 Compact GSM/UMTS Multi-mode Outdoor BTS

Both the indoor and outdoor BTS support stackable configuration, which simplifies the

transportation, installation and expansion. Based on the all-in-one design architecture, the power

consumption is reduced considerably, which enables saving the investment on the site

infrastructure and OPEX.

Distributed multi-mode BTS: DBS3900 (BBU3900 + RRU3008+RRU3804)





Figure 35 Distributed multi-mode BTS

Distributed multi-mode BTS is application of module-based multi-mode. In this application, RF

module and baseband module can support GSM and UMTS respectively. The BBU and RRU are

connected with optical fiber, so there is no feeder loss, and RRU can be mounted near the

antenna to realize wider coverage.

RF module, RRU3008 can support 6 TRX in 1 module. RRU 3804 can support 4 cells in 1 module

and have the ability to evolve to LTE. Baseband module, BBU3900 can be applied in

GSM/UMTS/LTE mode by plugging in different daughter card. Meanwhile, baseband and

transmission can expand separately.

5.2.2 Multi-mode Solution based on Software Defined Radio (SDR)

SDR is the abbreviation of “software defined radio”. It means taking the hardware as an unified

platform, and re-program and reconstruct the equipment by software (Much of the waveforms,

e.g., frequency, modulation/demodulation, coding, etc) to support multi-mode. The signal path

can be reconfigured in software without requiring any hardware modifications. In conclusion, SDR

is a new wireless framework based on DSP/FPGA and software. To be emphasized, the research

of SDR technology is just in initial phase, SDR mentioned in this proposal is just for dual-mode in

the same frequency.

SDR is considered as a trend for 3G and the evolution afterwards 3G by ITU. And it‟s gradually

recognized by the industry for its smoothly evolution. Huawei keeps leading in SDR R&D, and has

integrated series of SDR products including RRU3908 and MRFU covering 850 MHz/900

MHz/1800 MHz/1900 MHz. After Huawei deploy the 1st SDR commercial network in Panama

AM(GSM/UMTS@1900MHz) in 2008 and 1st SDR commercial network comply with ETSI in

Finland Teliasonera in 2009, over 10 operators have chosen Huawei SDR BTS to construct G/U

multi-mode network. All these prove that Huawei SDR technology is mature and available for

great scale deployment.

SDR can be widely used for dual-mode network construction, e.g.: GSM&UMTS modernization,

GSM900MHz refarming, GSM850M/1900MHz refarming, new network for future evolution. It can

bring long-term TCO saving and has great advantage in smooth evolution,

Scheme of SDR Digital Transceiver

SDR digital transceiver includes wideband antenna, RF front-end, wideband ADC&DAC, DSP, and etc:





Figure 36 Scheme of SDR digital transceiver

RF Section

RF Section transmits/receives RF signal from the antenna. To settle for the requirement of SDR, the work frequency band of TX&RX&Antenna must be wide and MCPA has high linearity.

IF Section

High-speed and wideband ADC&DAC is the key part of SDR, it performs analog-to-digital conversion (on receive path) and digital-to-analog conversion (on transmit path), respectively.

Baseband Section

Baseband section performs baseband operations and also implements the link layer protocol. Some fixed function parts, like filter and DUC&DDC, are made of FPGA, which can be re-program, and has more flexibility and higher speed than DSP, smoother parts need complex calculation, are made of DSP.

SDR Solution

In order to meet the requirement of operators‟ G/U deployment, Huawei presents multi-mode BTS

solution, which is applicable for multi-mode deployment and is able to evolve from EDGE to

HSPA to HSPA+ to LTE.

SDR technology is an important part of Huawei‟s multi-mode BTS solution and including

cabinet-based and distributed multi-mode BTS.

Figure 37 Huawei SDR Modules





Cabinet-based multi-mode BTS: BTS3900 and BTS3900A (BBU3900+MRFU)

The cabinet-based multi-mode application has reduced footprint by sharing common G/U

platform and using SDR RF module. Cabinet-based multi-mode BTS is capable of evolution to

LTE.

MRFU

MRFU cover full spectrum: 900MHz or 1800MHz or 1900MHz. One MRFU maximum supports 6

GSM or 4 UMTS carriers, 4TRXs+2carriers or 5TRXs+1carrier for G/U dual mode. 80W output

power and 15MHz PA frequency bandwidth can meet the requirement of macro BTS and support

power sharing.

and provide 80w power output. The stackable cabinet, easy for transportation and installation,

only need 1 cabinet footprint, 100% reuse site facilities: less consumption of power, battery,

feeder and antenna. The capacity of GSM&UMTS can be adjusted dynamically by software

control.





Outdoor BTS3900A

BBU can be shared by GSM and UMTS and inserted into the 2U space reserved in the outdoor

power supply cabinet. MRFU can support dual-mode simultaneously, like G/U, G/L, U/L, and

provide 80W power output. Both the indoor and outdoor BTS support stackable configuration,

which simplifies the transportation, installation and expansion. Thanks to the all-in-one design

architecture, this enables saving the investment on the site infrastructure and OPEX.

Distributed multi-mode BTS: DBS3900 (BBU3900 + RRU3908)

Figure 41 Multi-mode BBU

Distributed multi-mode BTS is application of module-based multi-mode. In this application, RF

module and baseband module can support GSM and UMTS respectively. The BBU and RRU are

connected with optical fiber, so there is no feeder loss, and RRU can be fixed near the antenna to

realize wide coverage.





Figure 42 RRU3908

Distributed multi-mode DBS3900 will support G/U/LTE convergence by SDR as following:

RRU3908 cover full spectrum: 850MHz or 900MHZ or 1800MHz or 1900MHz.

One RRU3908 maximum support 6 GSM or 4 UMTS carriers, 4TRXs+2carriers or

5TRXs+1carrier for G/U dual mode.

Various clock supply: IP clock, or UMTS get clock signal from GSM E1/T1,save BITS

RRU 60W output power can be shared between multi-carriers in the same mode to get

flexible configuration.

Smooth evolution to HSPA+ (64QAM, 2*2 MIMO by software update),hardware is ready for

LTE.

5.3 Highlight s of Huawei’s SingleRAN Solution

5.3.1 Highlight of Huawei‟s GSM Solution

5.3.1.1 TCO Saving Solution

Transmission Saving Solution

Abis Transmission Saving

1. Abis IP over E1/FE/GE

Huawei provide Abis IP over E1/FE/GE to reduce transmission cost. Abis IP over FE/GE adapts

to all IP development trend of future transport layer and protocol development. The Abis interface

incorporates the features such as high bandwidth and low cost deployment, and it does not have

any restrictions on the BSC capacity. The low IP network deployment cost, short construction

period, and easy maintenance effectively reduce the CAPEX and OPEX of operators. Operator

which owns transport network resources, Huawei proposes IP over E1 and TDM over E1. Thus,

telecom operators can use the existing TDM network to protect the investment and reduce the

transmission cost.

2. Abis MUX





Figure 43 Abis MUX

Abis MUX is used to save the bandwidth and multiplex the packets. The BSC and the BTS serve

as transmitting end and receiving end of each other. When Abis MUX is applied, the transmitting

end multiplexes the UDP packets that meet the multiplexing condition. Multiple UDP packets are

multiplexed into one IP/UDP header at the transmitting end and then demultiplexed at the

receiving end to reconstruct the original data in the IP/UDP packets. Thus, the transmission

efficiency is improved and the bandwidth is saved.

By multiplexing and demultiplexing the IP/UDP packet, Abis MUX reduces the overhead of each

IP packet, increases the efficiency of the IP transmission, and saves the bandwidth.

3. BTS Local Switching Solution

With BTS Local Switching solution, if the calling MS and called MS are within the coverage of the

same BTS or BTS group, the BSC performs the loopback on the cabinet group of the convergent

BTS, only the signaling is sent to BSC when the calling and called parties are under the same site.

This feature helps save the local or long-distance transmission resources on the Abis and Ater

interfaces.

Figure 44 BTS Local Switch Solution

4. Abis Congestion Triggered HR Allocation

In heavy traffic hours, if the Abis transmission resources are not sufficient, the Abis

transmission may be congested earlier than the air interface. The TCHF-to-TCHH conversion

based on the air interface load and the mechanism of preferentially allocating TCHH cannot

guarantee the system capacity. Based on the congestion status on the Abis interface, the Abis

congestion triggered HR allocation function performs dynamic TCHF-TCHH conversion,

preferentially allocates TCHH, and carries out queuing and pre-emption to ease the Abis

interface congestion and to increase the system capacity. So this function can helps save the

Abis transmission resources and reduce the network construction cost.





Power Consumption Saving

With leader solution, Huawei has introduced a new design chipset which can decrease the

Power consumption as compare to traditional chipset design. Being introduce new chipset the

static power consumption reaches up to less than 50%.

Figure 45 New IC Technology

Intelligent Power Management system

Figure 46 Power Optimization Based on Channel Type

Huawei intelligent power management system allows BTS to select best PA-bias dynamically for

GMSK and 8PSK codec which increases the PA efficiency by 10%.





Figure 47 TRX Power Amplifier Intelligent Shutdown

Using intelligent shutdown of TRX by time function, operator can specify a period of low traffic

time. In this period, the BSC commands the BTS to shut down some TRXs in a cell. When the

period ends, the BSC commands the BTS to switch on the TRXs. Likewise, intelligent shutdown

of the idle TRX in time slot level and priority assignment of time slots in BCCH TRX decrease

power load in PA. Hence, typical power consumption of BTS3900 (TOC=20W, load factor=30%)

for S2/2/2 configuration is only 500W which is the leading value in the industry level.

By this way, the power management and self-protection of the system is enhanced. Thus raises

the reliability of the system and prolongs the life cycle of the product.

In a 900 MHz/1800 MHz dual-band network, Dynamic Cell Power Off feature is

generally used to save more power consumption.

In a specified period, if the traffic is low and a 900 MHz cell can carry all the traffic in the coverage

area of an 1800 MHz cell, then the 1800 MHz cell can be powered off to reduce the power

consumption of the BTS.

By powering off the idle network devices in low traffic hours, the consumption of resources can be

reduced. This also reduces the operational expenditure of the operators.

Figure 48 Dynamic Cell Power Off





Active Backup Power Control

Figure 49 Active Backup Power Control

Once the external power of the BTS is disrupted, the BTS uses the backup battery to supply the

power. Huawei provide this function to gradually shut down the TRXs and decreases the transmit

power of the TRX to prolong the service time of the BTS.

This function decreases the power consumption of the BTS, prolongs the service time of the BTS,

and decreases the out-of-service cell rate when the external power supply of the BTS is disrupted.

And it also can increases the discharge time of the battery, saves the working time of the

generator, and thus saves the cost of the power supply.

PSU Smart Control

The PSU (Power Supply Unit Module) intelligent shutdown function shuts down the redundant

PSUs based on the BTS load on the condition that the required power consumption of the BTS is

met.

This function improves the efficiency of the power conversion, prolongs the working time and

lifetime of the PSU, reduces the power consumption, and saves the operating cost.

Enhanced BCCH Power Consumption Optimization

In traditional BTS, the transmit power of the main-BCCH carrier is fixed. Huawei Enhanced BCCH

Power Consumption Optimization function can reduce the transmit power of the non-main BCCH

timeslots on the main BCCH carrier to decrease the power consumption of the BTS.

5.3.1.2 Enhanced Capacity Solution

Soft Synchronized Network





Figure 50 Network Synchronization

The Soft Synchronized Network is one of Huawei unique features. The software synchronized site

can synchronize the BTS TDMA frame without GPS engineering. This feature is especially useful

in two scenarios: high density traffic load area or limited frequency resource.

Huawei could support Um interface software synchronization intra BSC and inter BSC without

adding any additional hardware. As Figure 48 shows, before network synchronization, a center

BTS should be identified. Here BS1 becomes the Center BTS. In the first round, BTSs surrounding

BS1 will be synchronized orderly, such as1-2, 1-3, 1-4…1-7. In the second round, the already

synchronized BTS become the Center BTS, synchronization among BTSs will carried out

according to specific sequence, like 2-8, 2-9, 3-10, 3-11, 4-12…7-19. Synchronization will repeat

till all BTS are synchronized. For intra-BSC soft synchronization, the soft synch error is less than

1.5 bit, a pair of synch tuning time is less than 5sec, and a pair of synch info-collecting time is less

than 5min.

Synchronized network means that all the GSM BTSs are in same pace. It can improve the radio

link quality by enhancing the ICC performance to 5~10dB, while co-existing with other

technologies, tighter frequency reuse rate can be realized and network capacity can be increased.

IBCA

IBCA (Interference-Based Channel Allocation) is a dynamic frequency and channel allocation

algorithm based on the prediction of the achievable CIR (Channel Interference Relation) of each

candidate channel and established channel.

Figure 51 IBCA





IBCA could be utilized under the condition where the spectrum resource is rare and dense

frequency reuse brings severe inter-cell interference which in stead of channel limits the network

capacity. IBCA bases on software synchronized network, no GPS needed, easy implementation. It

lessens the over interference level in the network and provides more effective frequency reuse

with ensured quality, thus the network capacity could be increased remarkably.

Tight BCCH Frequency Reuse

In order to improve spectrum efficiency, Huawei introduces the tight BCCH frequency reuse. The

multiplexing mode of the BCCH frequency is changed from 4 x 3 to 3 x 3, thus three frequencies

are added to the frequency hopping. After 1 x 1 frequency multiplexing is used, each cell can be

added with one TRX and the system capacity can be improved by around 25%. For operators, just

through enabling the function, the following benefits could be obtained.

Decreasing number of frequencies occupied by BCCH and improving spectrum frequency

Increasing available frequencies for TCH and frequencies for frequency hopping

Increasing frequencies for frequency hopping

Expanding the system capacity without adding new hardware

Saving the costs for adding sites and cells. The TCH channel on the BCCH frequency is

used by the MSs near the BTS. The subscribers can obtain improved speech quality when this

function is enabled.

The random access failures decrease and the access performance increases.

5.3.1.3 Enhanced Coverage Solution

Leading RF Performance

High TOC Output Power

Huawei GSM BTS series also adopt Multi-carrier Radio Frequency Unit (GRFU). Each GRFU

can serve as six TRXs. The max TOC power is 49.0dBm at GMSK mode or 47.2dBm at 8PSK

mode respectively without any degradation of capacity or additional antenna systems.

High Receiving Sensitivity

With the 3G RF design technology introduced, Huawei BTS has been improved in processing RF

and baseband signals, particularly the performance of the baseband demodulation algorithm. So

the static receive sensitivity of a single-channel reaches -113dBm, the uplink coverage of the

GSM network can be improved up to 20% compared to the industry level with the receive

sensitivity as -110dBm. Besides, 2-way receive sensitivity is -116dBm. Operators could further

enlarge the uplink coverage just through software configuration.





Satellite Transmission

The satellite transmission mode is a supplementary for the common transmission. Huawei BSS

support satellite transmission over all interfaces on BSS part:

satellite transmission over Abis interface

satellite transmission over A interface

satellite transmission over Ater interface

satellite transmission over Pb interface

EDGE service over satellite transmission

Extended Coverage

CS: Extended Cell

In GSM specifications, limited by timing advance (TA) 63 bit, the standard maximum GSM cell

radius is 35 km. In regions such as vast land, seashore, where with scattered subscribers in low

traffic, and the infrastructure facilities such as transmission and power supply are hard to be

constructed or unavailable. The radius of cell shall be over 35 km.

Huawei extended cell technology breaks the limit of the 35 km and realizes the wide coverage.

Supported by BTS hardware, it can cover a range with radius of up to 120 km. It has been

implemented successfully in Qindao seashore coverage project since 2004; the maximum

coverage distance reached 120 Km.

PS：Enhanced downlink throughput in dual-timeslot extension cell

Figure 52 Enhanced downlink throughput in dual-timeslot extension cell

For the PS service, Huawei proposes dual-timeslot extension cell in order to enhance downlink

throughput. The cells with coverage over 35 kilometers, such as coast coverage, island coverage,

or wide coverage on land, support the PDCH allocation of four downlink timeslots and one uplink

timeslot can be performed for the MS with the multi-timeslot capability. The extension cell can

provide a data throughput four times of that provided by a traditional cell (single downlink timeslot

connection), and thus accelerates the download tasks of the MS, improves the user experience,

and helps the operators make more profit out of data services.





5.3.1.4 Performance Enhancement Solution

AMR&WB AMR

Figure 53 AMR

AMR can select the traffic channel mode (FR or HR) and the coding mode according to the

channel quality and load. Therefore, AMR contributes a lot in better speech quality, improved

bearer capacity of the system in physical regions and stronger anti-interference capability. It could

balance the network quality and capacity, increasing about 40% network capacity.

Presently, Huawei BSS technologies support NB-AMR and WB-AMR (both FR and HR). Just

through software configuration, operators could realize both AMR FR and AMR HR functions

according to the specific network condition. Besides, Huawei BSS technology could dynamically

switch AMR FR/HR, leading to up to 40% capacity increase without degradation of service quality.

As the system could automatically adjust, the maintenance cost could also be decreased. WB

AMR provides clear and loud voice and high-quality speech compared with the narrow band AMR

with the sampling rate of 8 kHz and the speech frequency range between 200 Hz and 3400 Hz.

In Huawei BSS technology, the AMR wireless link timer is utilized to detect the quality of a

wireless link. By setting the wireless link timer of AMR voice service and that of non-AMR

voice service separately, the operator could prolong the conversation of AMR voice service,

reduce the call drop rate, and increase benefits and win a high subscribers‟ loyalty.

Enhanced EDGE Performance

When GSM/EDGE radio access network (GERAN) evolution introduced in the network, The rate

of PS services in the uplink and downlink is increased greatly. When four timeslots are used for

uplink data transmission, the theoretical rate of EGPRS is increased from 230 kbit/s to 300 kbit/s.

When ten timeslots are used on the downlink, the theoretical data rate of EGPRS is increased

from 592 kbit/s to 984 kbit/s.

In order to realize it, Huawei adopts following technologies to enhance the PS service.

MSRD:





The receiver sensitivity of the MS is increased by about 3 dB and the downlink coverage distance

is increased. In conjunction with the dual-antenna interference cancellation (DAIC) technology, the

MSRD feature improves the anti-interference capability of the downlink, thus expanding the

downlink traffic capacity.

Dual Carriers in Downlink

With dual carriers in downlink, the GSM network can provide subscribers with data services similar

to those provided in a 3G network.

Uplink EGPRS2-A

With the 16QAM modulation, the theoretical rate of EGPRS is increased from 230 kbit/s to 300

kbit/s.

Downlink EGPRS2-A

With higher order modulation (16QAM and 32QAM), high symbol rate (1.2 times), and Turbo

codes,, When ten timeslots are used on the downlink, the theoretical data rate of EGPRS is

increased from 592 kbit/s to 984 kbit/s.

Latency Reduction

This feature reduces the packet transmission latency and thus improves the customer satisfaction.

Figure 54 EDGE evolution

Priority Control for Different Level Users

eMLPP+HR, providing different classes of services for the users with different priorities, ensures

VIP service quality.





Figure 55 BSS eMLPP+HR Solution

The eMLPP services means to implement different policies for the calls of different priorities when

network resources are seized; The HR (Half Rate) voice services allow two users to share the

same TCH timeslot. Through channel reserved and preemption, it principally assures resources

for high-end subscribers or emergency calls. According to priority, this feature can allocate FR

channels and good speech quality for high-end users. Introduced HR technology, network

capacity can be double without any addition of TRXs. To decrease the congestion rate, the

network real time dynamically adjusts the channel type between FR and HR

Voice Quality Enhancement Technologies

High voice quality is a prerequisite for subscriber retention. In order to realize it, Huawei adopts

following technologies to enhance the voice quality.

5.3.1.5 ALL IP BSS Network Solution

ALL IP BSS Solution Introduction

Figure 57 ALL IP BSS

Huawei is the first vendor in the industry to provide All IP BSS solution. Huawei BSC supports IP

over FE/GE, IP over TDM (E1/T1, cPOS).

Huawei BSS also can provide all IP interface, including Abis over IP, A over IP, and Gb over IP.

Based on ALL IP solution, the TrFO function can be supported to improve the voice quality and TC

resources can be saved. Meanwhile, the MSC in pool, the SGSN, in pool can be supported easily.

IP transmission offers sufficient bandwidth to the BTS, thus, new services can be developed

conveniently and efficiently. Operator can also have cheap rent fee, launch services quickly and

maintain network easily, Huawei IP BSS network can help operator reduce total cost.

Moreover, Huawei launched an advanced technology to ensure ALL IP BSS network, IP clock to

provide clock synchronization for several BTSs in the IP network and Abis MUX improves the

transmission efficiency. Huawei IP BSS also provides different QoS mechanisms in each layer to

guarantee the end-to-end QoS, and so on.





Clock Over IP Support 1588V2

Figure 58 Clock Over IP Application

Clock over IP that complies with IEEE1588V2 provides clock synchronization for several BTSs in

the IP network. Compare with the GPS clock, it is a low-cost clock solution. The transmission cost

increases because the IP timing packets are sent continuously. The function provided by Huawei,

however, allows the operator to define the interval for sending IP timing packets. It can reduce the

transmission bandwidth as long as the BTS clock synchronization is guaranteed.

Ethernet OAM

With the introduction of IP GSM, the Ethernet as a type of transport bearer is widely used. As a

Layer 2 protocol, Ethernet O&M can report the status of the network at the data link layer. Thus,

the network is monitored and managed more effectively. The functions of Ethernet OAM consist of

fault detection, notification, verification, and identification. The faults involve the hardware faults

that can be detected by the physical layer, such as link failure, and the software faults that cannot

be detected by the physical layer, such as memory bridging unit damage. Ethernet O&M plays a

significant role in reducing CAPEX/OPEX and complying with the Service Level Agreement (SLA).

Figure 59 Ethernet OAM





5.3.1.6 Network Reliability

MSC Pool

The MSC pool, one BSC can be connected to multiple MSCs simultaneously. With this feature, a

maximum of 32 MSCs form a resource pool to provide services for the subscribers under one

group of BSCs. In addition, the traffic on the BSC is evenly distributed to the MSCs in the pool

according to the NRI or load balancing principle.

The MSCs in an MSC pool share the traffic load and resources. Therefore, this feature provides

the following benefits:

MSC pool increases the network capacity and saves the equipment investment.

MSC pool realizes the redundancy backup and thus improves the network reliability because

the addition or deletion of an MSC does not affect the services.

MSC pool automatically adjusts the traffic load on an MSC and reduces the operation and

maintenance cost of operators.

The MSC pool is logically an MSC. Therefore, the number of handovers between MSCs is

reduced and the network performance is improved.

The following figure shows the typical networking of the MSC Pool feature:

SGSN Pool

With SGSN Pool, one BSC can be connected to multiple SGSNs at the same time. This feature,

which is similar to the MSC Pool feature, enables a maximum of 32 SGSNs to form a resource

pool to provide services for the subscribers belonging to one group of BSCs. In addition, the traffic

on the BSC is evenly distributed to the SGSNs in the pool according to the network resource

identifier (NRI) or load balancing principle.





The SGSNs in an SGSN pool share the traffic load and resources. This feature provides the

following benefits:

Increases the network capacity and saves the investment on equipment.

Implements redundancy backup and thus improves the network reliability because the

addition or deletion of an SGSN does not affect the services.

Reduces handovers between the SGSNs because the SGSNs in an SGSN pool are logically

one SGSN and thus improves the network performance.

TC POOL

In general, one GTCS belongs to only one BSC and is used to process the CS services of this

BSC. The GTCSs in different BSCs are not associated with each other. In this kind of network

topology, the TC resources cannot be multiplexed among multiple BSCs. In the scenario where

multiple BSCs with small capacity are grouped into a network, the TC resources are greatly

wasted.

The TC pool adapt to the mode that the GTCS is separated from the BSC cabinet and is

connected to the BSC through the Ater interface. The codec resources in the TC pool are shared

by the main BSC and sub-BSCs, which work in load sharing mode. In addition, a BSC can be

connected to only one TC pool. One TC pool supports a maximum of 16 BSCs.

The efficiency of the codec hardware can be increased because multiple BSCs share the same

resources in one TC pool. For the small-capacity BSC, 20% to 30% TC codec resources can be

saved.

Roomage is saved. For example, three small-capacity GTCSs require three cabinets. In TC pool

mode, three GTCSs require only one cabinet. In this manner, 40% to 60% area in the equipment

room can be saved.

The typical network topology is shown in the following figure.

5.3.2 Highlight of Huawei‟s UMTS Solution

5.3.2.1 High Performance HSPA/HSPA+ Solution

With self-designed HSPA chipset, high performance HSPA can be achieved in Huawei UTRAN

products from day one, supporting full performance HSDPA with 15 codes /14.4 Mbps per user on

downlink and HSUPA with 5.76Mbps/user on uplink. For HSPA+ phase1, Huawei supports

21Mbps and 28Mbps per user on downlink with 64QAM and 2x2MIMO technique respectively.

In order to save evolution investment and keep the leading position of UMTS, Huawei is

recommending HSPA/HSPA+ deployment strategy as follows:

High performance HSPA/HSPA+ capability

To support high performance HSDPA and avoid hardware upgrade at the next stage, the Node B

should be ready to support full HSDPA performance from day one. Huawei supports this

philosophy by offering a Node B that supports 15 codes and peak bit rates at 14.4Mbit/s per cell.

Besides that, Huawei Node B supports all the 12 UE categories, avoiding system upgrade

investment along with the UE capability improvement.

Huawei HSUPA solution supports E-DCH TTI 10ms and 2ms, peak data rate up to 5.76Mbps.

Huawei has helped StarHub Singapore, eMobile Japan, Vodafone Spain, etc. to launch HSUPA

commercially with 1.92Mbps since 2007Q3.

With Huawei‟s advanced new generation Node B and RNC, Huawei can also provide high

performance HSPA+ phase1 solution, which has the ability to evolution to HSPA+ phase2

smoothly.

Coverage improvement

In HSDPA solution, Huawei supports HS-DPCCH preamble mode technology help the Node B to

distinguish between DTX and ACK/NACK without requiring a large ACK transmit power. In this

way, the uplink coverage gain is about 0.2dB to 0.9dB with different accompanying DPCH service.

DL 64QAM+MIMO improves user DL throughput and cell throughput

a) Introduction of DL 64QAM +MIMO

MIMO and 64QAM are introduced in 3GPP Release 7 and can only be used independently. In

3GPP Release 8, however, MIMO and 64QAM can be used in combination to increase the peak

throughput of a single user.

With 64QAM+MIMO, the peak throughput of a single user can reach 42Mbit/s, compared to

28Mbit/s with 16QAM+MIMO or 21Mbit/s with 64QAM only.

b) Benefits of Huawei MIMO solution

MIMO proved to bring high performance in spectral efficiency, cell capacity and user

throughput across the whole cell

MIMO deployment options can be a cost effective way to increase networks value

and end users perception

Major MIMO deployment issues could be solved





Legay 1Tx RF cascade and new 2Tx RF solution

Improve cell throughput about 11.7% in Micro cell vs DL 64QAM

Figure 63 Cell throughput comparison of DL MIMO+64QAM vs DL 64QAM

For network where MIMO has been configured, combined application of 64 QAM and

MIMO will obtain relatively high gain in the micro cell.

For network where 64QAM has been configured, combined application of 64 QAM

and MIMO will obtain gain in both macro and micro cell and the gain is mainly from

the application of MIMO technique.

that Huawei is 2 year ahead industry for MIMO hardware ready.

In DL 64QAM and MIMO, Huawei is about one year leading ahead of other vendors both for

software and hardware ready.

DC-HSDPA Solution improves network performance

1) Introduction of DC-HSDPA solution

HSPA+ data can also be transmitted by the combination of two or more carriers and

this result in double or more times of data throughput. HSPA+ based on R8 uses

two carriers of consecutive frequencies in downlink and named as Dual Cell

HSDPA (DC-HSDPA). If both the network and the user equipment are capable of

Dual-Carrier HSDPA operation, the network will be able to configure the user

equipment not only with a (primary) serving cell but also with a secondary serving

cell originating from the same base station but on an adjacent carrier frequency.

Figure 64 DC-HSDPA working principle

2) Key benefits of DC-HSDPA solution

DC-HSDPA is an alternative of MIMO to improve the data throughput and users‟

experience. The carrier aggregation process enables the increase in capacity and user

throughput. The key benefits of DC-HSDPA are improved user experience, easy

deployment and low network cost.

a) Improve User Experience & Network Performance

DC-HSDPA provide higher throughput to the end-users even they are far from the

transceiver. The coverage performance of a DC user is higher than every other HSPA

user.





Figure 65 DC-HSDPA service coverage comparison with other HSPA users

(Remark: from Huawei lab test)

b) Easy Deployment and Low Cost

For a deployed network, it is easy to upgrade it for the DC-HSDPA, no new antenna

configuration and no new transceivers required for DC-HSDPA. The cells only need

software configuration for DC-HSDPA if the network is already operating on the multi

frequency configurations in a same coverage area. For the areas where the cell is

covered by one carrier frequency only, there will be new requirement for another

carrier and it will cost some extra amount.

c) Decreases burst service and HTTP service relay remarkably

DC-HSDPA has best performance for the burst services like http, gaming or small

size download files. The burst services consume a small amount of resource and

users‟ transmission time is small, therefore; DC-HSDPA cells can easily share

their resources to all the subscribers.

d) Utilizes operators frequency resources and improves capacity and be compatible

with original terminals well.

3) Unique benefits of Huawei DC-HSDPA solution

a) Only software upgrade is needed for legacy market supporting DC-HSDPA

b) The network elements developed by Huawei are hardware ready for the

DC-HSDPA operations and only software up-gradation required. The SingleBTS

NodeBs and 6810/6900 series RNC types are capable to support DC-HSDPA

functionality through software up-gradation. The joint scheduling, channel

mapping and radio resource management are handled only by the software

change in the legacy elements.

c) Large capacity of baseband board, one board of 6 cells can support 2 carrier

DC-HSDPA.

d) First to provide Multi Carrier Transceivers.





UL 16QAM increases system capacity of HSUPA cells

a) Introduction of UL 16QAM

HSPA+ uses HOM techniques in uplink to increase the number of bits per data symbol and

hence to increase the cell throughput capacity. In uplink, HSPA+ uses a 16QAM modulation

scheme instead of QPSK (Quadrature Phase Shift Keying), the number of bits per symbol

increases from 2bits to 4bits and hence the Uplink peak data rate can reach up to 11.5 Mb/s.

Figure 1-12 and Table1-3 gives the details descriptions of UL modulation schemes.

b) Benefits of UL16QAM

c) Raise the user peak rate and cell throughput

d) Obtain higher performance in Micro cell and indoor area than in Macro cell

e) Summary of UL 16QAM solution

f) Uplink 16QAM modulation scheme increases in uplink data throughput from 5.76Mps to

11.5Mbps. This is a 100% improvement over the previous 3GPP release of HSUPA.

g) UL 16QAM improves the UL data transmission performance and increases the system

capacity of HSUPA cells.

h) Leading position of Huawei UL 16QAM in industry

Huawei is around one year leading ahead of other vendors in UL16QAM.

HSPA+ Global Deployment

HSPA+ has quickly been embraced by many of the world‟s leading operators. More and more

operators had commercially deployed HSPA+ and more than 50 were engaged in vendor trials. It

is expected that by 2010 many more operators will have commercially deployed HSPA+.

GSA Survey on Global HSPA+ Commitments and Deployments on April 14 2010: Totally 101

HSPA+ networks, among which 51 commercial HSPA+ network, 50 HSPA+ networks in

deployment or planed. By Q1 2010, Huawei had already won more than 27 commercial HSPA+

5.3.2.2 MBMS Solution

Overview

As one of the Leading Mobile MBMS vendors in the industry, Huawei has made some great

achievements in MBMS solution as the following:

Due to heavy investments in MBMS technology, Huawei holds 22% of the ETSI MBMS

patents.

1st vendor to perform live MBMS demo in Barcelona with 256Kbps worldwide.

Helping PCCW deploy first commercialized UMTS network with simplified MBMS

technology (CMB) in Hong Kong.

Huawei High-quality and More Competitive MBMS Solution

MBMS solution immediately launched by Huawei will have more enhanced features.

a) Supporting enhanced broadcast solution

Figure 68 Huawei MBMS Solution

Huawei MBMS broadcast solution is the unidirectional transmission of multimedia data (such as

text, audio, picture, video) from a single source entity to all users in the broadcast service area, it

includes P-T-P (point-to-point) mode and P-T-M (point-to-multi-point) mode. The enhanced

broadcast solution supports “counting/re-counting” function. Based on “Counting/re-counting”

result, RNC can select optimum transfer mode: PTM or PTP. In PTM mode, FACH/SCCPCH is

used to bear the MBMS services; in PTP mode, DCH or HSDPA is used to bear the MBMS

services. If in a cell there is no user interested in one specific MBMS service, RAN can decide to

cancel the service automatically.

b) Innovative Iub Transmission Sharing Solution Saving 66% Transmission

Resources

Figure 69 Iub Transmission Sharing





Usually FACH channels in Iub interface are used to transport multimedia broadcast data

services from RNC to a few cells in a Node B. Without Iub transmission sharing, each cell must

have a FACH channel for transporting the data services from RNC so that more transmission

resources must be required in Iub interface.

By Huawei innovative Iub transmission sharing solution, a few cells in a Node B can share a

FACH channel if all the cells broadcast the same services. We can take 3x1 Node B for an

example, 66% transmission resources can be saved if 3 cells share a FACH channel. Obviously

operators can benefit from Iub transmission sharing solution.

c) Supporting MSCH

Huawei MBMS solution can support MSCH. Although MSCH is optional in 3GPP, Huawei

MBMS solution can support MSCH from day one. With the help of MSCH, MBMS terminal

power consumption can be reduced.

Continuous Efforts in MBMS and Bright Future

For a long time, Huawei has been dedicated in MBMS research in specifications and patents. Up

to now, 14 Huawei patents have been stated to ETSI and covered the total patents by 22%. With

some leading operators such as Vodafone, Huawei has been making efforts to promote the

development of MBMS in the industry. In-depth MBMS research and rich CMB commercialized

experiences have helped Huawei to take a leading position in MBMS solution.

5.3.2.3 UTRAN IP Transmission Solution

Overview

As IP technology is implemented more and more widely, IP becomes the most used transport

technology with the best cost efficiency. With the development of HSDPA and HSUPA, more

transport bandwidth will be needed. UTRAN IP transmission will be a good choice for operators.

Figure 70 UTRAN IP Transport Solution

Based on the current IP network condition, Huawei provides several UTRAN IP transmission

solutions. For Iu interface, Huawei provides Ethernet interface. As for Iub interface, Huawei

provides ATM access method for traditional ATM network whereas Ethernet interface for IP





network. In order to use popular ADSL port, Huawei also provides ADSL access method. Likewise,

to guarantee the quality of voice and to lower cost, Huawei provides hybrid IP transmission.

IP over ATM Transmission Solution

Since ATM transport is the popular transport resource currently, IP over ATM is necessary. When

ATM Transport network carries Iub interface data, RNC and NodeB provide E1/T1 interface to

access ATM transport network. Huawei Iub interface IP protocol is compliant to 3GPP protocol,

UDP carries FP frame, and SCTP carries NBAP data. Huawei provides TCP to carry O&M data.

Huawei E1/T1 Iub interface supports ML-PPP/HDLC function in order to provide higher

bandwidth.

The highlight of IP over ATM:

Enhance the quality of IP service because ATM can provide the QOS guarantee.

Good ability of flow control and fault resilience, have good network reliability.

Suitable for multi-service, has a good network extension.

Figure 71 IP Transport based on ATM Transport Network

All IP Transmission Solution

In future, IP network will become more popular and will be used for Iub interface. RNC and NodeB

can then be connected to each other directly by metro Ethernet network through their FE

interfaces to access data communication network.

In general, NodeB cannot connect with RNC within the same metro Ethernet. NodeB needs to

access to metro Ethernet first, then access to IP network by edge router. However, RNC can

access directly to IP network.

For NodeB, the last mile access method is abundant, such as ADSL, SHDSL, MSTP, xPON, and

so on.

To solve the line synchronization for all IP transmission, Huawei provide clock over IP solution

instead of GPS to greatly reduce investment.





Figure 72 IP Transmission based on IP Transport Network

Hybrid ATM/IP Transmission Solution

When the traditional UMTS network introduces HSDPA/HSUPA, The Traffic of RAN will be

increased greatly. If adopt traditional TDM transmission, the cost will be too huge to be accepted

by Operator. Due to the complexity of access network, If we adopt all IP transmission between

Node B and RNC, the QoS of real time service, such as Voice and Video Phone, cannot be

assured. In order to reach the balance of QoS and cost, Huawei introduces the IP Hybrid Base

Station Transmission Solution, which can solve the QoS of Network with low cost. Huawei

proposes the use of hybrid transmission solution on Iub interface whereby voice traffic will be

carried by TDM/ATM transport network and best effort traffic carried by IP network.

Figure 73 Hybrid IP Transmission Solution

5.3.2.4 Co-site Solution

Overview

In order to speed up the construction and to cut down the CAPEX for setting up UMTS Network, it

is very important to share the existing facilities and the sites as far as practicable. Huawei is

experienced at 2G & 3G systems sharing the facilities and sharing the sites. Relying on this

experience, Huawei has summarized several general principles for 2G & 3G systems sharing the

facilities and the sites.

The UMTS network shall be of the excellent performance and 2G network performance has no

regression, even adopting 2G & 3G sharing sites solution.

Adoption of 2G & 3G sharing site solution shall insure the clear boundary between two Network

structures and systems, in order for easy maintenance and system management, and no

networks and no services cross-interfering.

The key objective for adopting 2G & 3G sharing site solution is to help the service provider

customer to cut down the CAPEX for constructing the new network. Any 2G & 3G sharing site

solution shall be obeying this economical rule.

Huawei’s Co site solution

The co site solution should fully consider the existing site conditions and the requirements of the

operator. The aspects of the co site solution shall include the space sharing, antenna system

sharing, transmission sharing, power sharing, etc. To ensure the reasonable reutilization of the

resource and the safety of the operation, the site survey and the detail site design shall be

conducted before the implementation. A general procedure for co site implementation is shown as

follows:

Antenna System Sharing

Due to the high cost of the installation and maintenance of the antenna system, the antenna

system sharing solution is always welcome to the operators. By the development of the antenna

technology, the sharing of the antenna and feeder system becomes more and more popular.

Huawei could plan and design the antenna system sharing solution based on the customer‟s

requirements and provide the necessary auxiliary equipments. Some typical antenna sharing

scenarios are shown as follows for sample:

Figure 76 Antenna Sharing Solution

Space Sharing

Depending on the space of the existing equipment room or shelter, Huawei will propose the

different product solutions accordingly:

If there is the enough space in the existing equipment room, Huawei will adopt indoor equipment.

During the on site survey and the engineering design period, Huawei will also evaluate the space

and the conditions and the life-span of existing shelters and consider the necessary alteration, in

order to install the new equipment and make the equipment operating normally.





If there is no enough space in the existing room for installing new equipment, Huawei will propose

and adopt the Distributing Base Station (DBS) equipment or outdoor equipment, in accordance

with the site conditions. Huawei will evaluate the cost of those two solutions during on site survey

and engineering design and select the best solution for customer.

Figure 77 Space Sharing Solution

Transmission Sharing

To some operators, the cost of the transmission renting or maintenance is another huge

disbursement, especially for those suburban sites. So the transmission sharing solution is also

very important to the operators. Through flexible sharing of the transmission system, the TCO

could be obviously saved. Huawei Node Bs support IP RAN and other transmission sharing

modes, which will let the operator have abundance choices on transmission sharing. The

recommended sharing solution is fractional ATM mode, which could use part of the timeslots of

the E1 to carry the ATM message.

Figure 78 Transmission Sharing Solution of Fractional ATM





5.3.2.5 RAN Sharing Solution

Overview

RAN sharing is an effective way to save CAPEX and OPEX., and approximate 30% ~ 40%

CAPEX and OPEX will be saved by RAN sharing. It can quicken the nationwide wide roll-out as

well. RAN sharing makes operators focus more on new and innovative services for end users with

less effort on roll-out and maintenances. RAN sharing brings better services, better quality of

experience and better coverage for end users.

Huawei can provide two kinds of RAN Sharing solution: Dedicted Carrier RS (MRNC) and Shared

Carrier RS (MOCN). In this proposal, Huawei introduces MOCN solution to SMART.

MOCN

In the MOCN solution, operators share resources of the entire UTRAN, including spectrum

resources. This solution is applicable to the following scenarios:

A 3G-licensed operator shares spectrum resources with other operators.

The operator who owns multiple spectrums uses these spectrums as a resource pool and

shares the pool with the operators who have no spectrums.

MOCN has the following characteristics:

The UTRAN of the shared area is constructed by one operator and shared by other

operators. These operators contribute their spectrum resources (if any) and share all

spectrum resources between each other (no matter whether an operator contributes

spectrum resources or not).

The shared RAN is connected to the CNs of multiple operators.

Each operator is allowed to deploy Iu Flex, and the CN nodes within an operator's network

form a CN pool.

The UEs in the same shared cell are routed from the RAN to the CNs of respective

operators.

The MOCN solution enables two to four operators to share RNCs and Node Bs and at the same

time to use their own CN. The operators work together to deploy CBS. With the application of this

solution, a cell can broadcast a Multiple PLMN ID LIST containing PLMN IDs of multiple operators.

The MOCN-enabled Supporting UE can choose a PLMN ID and send it to the RNC. The RNC

selects an appropriate route for this UE. If a Non-supporting UE exists in the shared cell, the UE

does not report any PLMN information to the RNC. Usually, at this time the RNC can determine a

route according to the PLMN ID derived from the IMSI or according to the NRI in the TMSI or

P-TMSI.

If the PLMN ID or NRI corresponds to one of the CNs that the RNC is connected to, the

RNC is directly routed to the corresponding CN node.

If the PLMN ID or NRI does not correspond to any of the CNs that the RNC is connected to,

the RNC tries to connect to each CN according to a certain principle. If the routing fails, the

RNC tries the next CN Node By following the Redirect process until the routing succeeds.

If the IMSI, TMSI, or P-TMSI is unavailable, the RNC keeps trying the CNs one by one according

to a certain principle.

The MOCN solution uses only one set of OSS equipment.

5.3.2.6 Smooth Evolution to HSPA+/LTE

The evolution paths for both distributed Node B and macro Node B is shown as follows:

Figure 80 Smooth Evolution to HSPA+/LTE

The Baseband Unit BBU3900 has 6 slots for base board, which supports the plug-and-play

function. The BBU is hardware ready for HSPA+ phase 1 (downlink 64QAM and MIMO 2 x 2)

and only need to add new baseband card to support HSPA+ phase 2 (uplink 16QAM) and

LTE respectively.

The RF Unit (RRU3804, RRU3908 and RF) is hardware ready for HSPA+, LTE, and only

need software upgrade to support HSPA+ and LTE at the same frequency band.





A continuous investment reduces the TCO, improving the coverage and capacity and enhancing

the maintainability makes Huawei proposed network solution a cost-efficient solution. Huawei

multi-mode solution has prominent features such as distributed structure, large capacity, high

performance, low power consumption, and so on, which help operators save TCO at great height.

The multi-mode Solution consisted of the solutions are as follows:

TCO Saving

With the development of GSM/UMTS, operators are more and more focusing on the construction

and operation cost of a network. Huawei focused on reducing CAPEX and saving OPEX for

operators from different aspects as follows. In each aspect, Huawei has adopted many advanced

technologies to save cost.

Unit-equipment: one deployment for 10 years‟ viability

Unit-site: Co-Auxiliary facilities

Transmission Saving: Local Call Local Switching, Hub BTS, etc.

Power Consumption Saving: Direct Cooling in power, High efficiency PA, Power sharing, etc.

Civil Work Saving: Distributed BTS, etc.

Co-OAM: one maintenance team, optimize human resources

Smooth Evolution: SDR technology, UMTS900&LTE hardware reuse

Enhanced Coverage

Quickly set up a network by reducing the number of sites will not only win the competition but also

save the TCO. The leading operators have adopted the latest enhanced coverage technology that

can be used in both GSM & UMTS. This Enhanced Coverage Solution reduces 30% cell sites as

follows:

Leading RF Performance: Higher receive sensitivity.

Remote Radio Unit: 3db feeder loss avoided with fiber connection.

Transmit Diversity/Dynamic Transmit Diversity

4-Way Receive Diversity

Satellite Transmission

Extended Cell

Performance Enhancement

Along with the development of GSM/UMTS network, VMS attracts subscribers by excellent

service, flexible charging, and abundant handsets. The total revenue increases with the addition of

new subscribers. However, the ARPU decreases. In this situation, VMS is facing pressures of

expanding network capacity and improving service types and quality. Huawei introduces a series

of technologies to enhance network performance for VMS:

AMR

Wireless broadband service based on Edge+/HSPA/HSPA+

Frequency Hopping





ICC/IBCA/Soft Synchronization

Dynamic MAIO

eMLPP +HR

Service Quality Enhancement Technologies

Smooth Evolution

Most of the operators have firmly believed that GSM/UMTS will evolve into LTE. That is a new

opportunity and challenge. With All-IP strategy, Huawei will build a future-oriented network for

operator and upgrade operator‟s network to LTE in the smoothest way. Huawei Smooth Evolution

Solution will save OPEX and reduce CAPEX by the ways such as reusing hardware and dynamic

capacity adjustment and so on.

5.3.3 High Transmission Efficiency /Improved Performance with 2G/3G Integrated

In multi-mode era, transmission cost counted as an important part of operator‟s TCO. Constructing

a cost-effective transmission network and being available for the need of the future evolution is a

challenge for all the operators. Huawei‟s co-transmission solution can solve this problem. It

includes two solutions based on different bearing network to fully reuse the exiting transmission

resource and protect customer investment.

Co-transmission Based on TDM network

Figure 81 Co-transmission Solution Based on TDM network

For some operators, they have an existing SDH network, and want to take back the investment as

soon as possible. Moreover, they have a difficulty in newly build an IP bearing network.

Therefore, Huawei provides this solution to fully use the existing TDM network. The GSM & UMTS

system can transmit the traffic in different TDM time slot independently on the SDH/PDH network

through the same E1/T1 line. UMTS BTS can adopt either ATM/IMA/Fractional ATM or IP/ML

PPP/PPP solutions. GSM can adopt TDM/ Abis over IP solutions. This makes the application

much more flexible.

Co-transmission Based on IP network





Figure 82 Co-transmission Solution Based on IP network

For some operators who have an existing IP network or wish to construct an IP transmission

network, Huawei‟s co-transmission solution based on the IP network can fulfill their needs.

The GSM & UMTS system can transport the traffic on the same IP network through the same

E1/FE/GE line. GSM & UMTS can share the transmission resources dynamically, so there will be

a transmission convergent effect, and the transmission efficiency will be enhanced.

As a single network, the resources of 2G&3G should be shared in the total system. How to

manage the resources to get the efficient and improved network performance? Huawei has done

a lot of effort on researching this field, we think it will be a trend of multi-mode network, and our

unique Co-RRM and Co-TRM solutions will be benefit and help to achieve customer‟s business

plan.

Co-RRM

Co-RRM is especially useful for the applications where different RAT cover the same area.

Co-RRM maximizes the efficiency of different radio access network by selecting a suitable

network for camping or accessing a subscriber. Co-RRM can further lead to reduce power

consumption by dynamically allocating traffic between different radio access technologies and

shutting down some carriers in a particular RAT.

With separate network implementation cell load information is exchanged by core network

intervention and it will have the associated signaling delay and also delay in handover procedures,

one of the unique advantages with MBSC and Co-RRM feature is that core network intervention is

avoided and thus it helps in reducing handover and associated signaling delays as shown in 0,

and reduce service interruption time to less than 680 ms.

- Improved Performance with Co-RRM





Figure 83 Co-RRM Solution

Co-TRM

Co-Transmission Resource Management (TRM) facilitates efficient access to 2G or 3G with

unique features such as Uni- Connection Admission Control (CAC), Uni-Flow control more

numbers of users can be effectively allocated to 2G/3G service. Co-TRM feature not only helps to

reduce maintenance trouble for the operators‟ but also helps to increase the efficiency of the

transmission resources.Morover, Co-TRM provide convergent solution and can be monitored and

maintained with Unified O&M.

Figure 84 Huawei OMC Solution

Huawei OMC solution supports the centralized O&M of CS, PS core, BSS and UTRAN

system, through OM network. The OMC solution includes three parts:

iManager M2000, which is the centralized element management system (EMS) with

full centralized management functionalities on Huawei NEs, including alarm





management, performance management, configuration management, software

management, security management etc.

GENEX serial OM tools, which is the Huawei‟s Radio Network Planning &

Optimization software applications, including GENEX UNet for network pre-planning

and planning, GENEX probe for drive test, GENEX Assistant for radio network test

data, GENEX Nastar for performance analysis.

Huawei LMT for each type of Network Element, which is the local maintenance

terminal installed software for specific NE‟s, capable of supporting full signal tracing

and trouble shooting functions besides the common O&M capability in NE level.

The M2000 and the LMT form two levels of an O&M system. Operators can manage and

maintain the authorized NEs via the M2000 Client, through the TCP/IP Ethernet network. The

major interface between M2000 and NEs is the highly efficient Man Machine Language (MML).

In case the connection fails or M2000 is unavailable, each NE will be managed and

maintained via the LMT respectively.

5.4.2 Huawei‟s Powerful iMananger M2000

iManager M2000 Mobile Element Management System can manage all the GSM&UMTS

network elements and the relative IP network equipments. In the future, the managed objects

(MO) of M2000 solution will include all IMS network elements. iManager M2000 has the

following characteristics:

Component based architecture

The CORBA component based architecture enables M2000 to expand its capacity smoothly

to meet network requirements. Besides that, the design flexibility enables it to be easily

extended with other components.

Implementing standard and open Northbound interfaces

The system supports standard 3GPP IRP CORBA solution sets, together with file interface,

database interface, alarm streaming interface, SNMP interface. These customizable open

northbound interfaces (Itf-N) well support customer to build a well-integrated OM system, with

an upper level NMS managing EMSs from multiple vendors.

Remote maintenance with security

By accessing M2000 system through PSTN remote dialup, a remote user can maintain its

UMTS network flexibly. All operations implemented by the remote user are monitored. When

the remote user quits, a maintenance report is generated automatically.

Software management

The system provides the function of transferring files between NE and M2000. M2000 can

download file to multiple NEs simultaneously, which hence improves file transfer performance

and reduces management work.





The system can also manage all software‟s versions of managed NEs. NE version

management functions include version information management, version file management,

version activation, etc.

Dynamic upgrade

M2000 system upgrade has no impact on NEs. The function modules of M2000 can be

upgraded independently.

Customizing performance report

The template and content of performance report can be customized flexibly. Users can do

further processing on generated reports, including printing, querying, statistics, etc.

Alarm correlation processing

Alarm correlation analysis and processing are performed based on the expandable alarm

rules.

Status monitor

The status of device boards, CPU, database, memory, and M2000 itself can be monitored

dynamically.

Resource statistics

System resources such as IP addresses, ports, signaling points, device boards, M2000 server,

and so on can be gathered and refreshed automatically.

Interface message tracing and user message tracing

Specified signaling messages of various interfaces can be traced, which enables users to get

the current network status and locate faults.

5.4.3 Abundant Northbound Interfaces for OSS Integrated Solution

As an element management system (EMS), the iManager M2000 provides abundant and

flexible northbound interfaces to the upper-layer network management system (NMS).

These interfaces include CORBA interface, the FTP file interface, SNMP interface, etc. The

flexible northbound interfaces offered by Huawei can help the carriers to:

Conveniently and quickly construct the operation and maintenance system

Integrate the NMS and Huawei‟s EMS

Seamlessly embed Huawei‟s mobile communication equipment in their original O&M

system

5.4.4 CME for Graphical Network Configurations and Tuning

Aiming at the complexity of wireless network configurations, Huawei offers the

Configuration Management Express (CME) with graphic interface. The CME provides users

with fast and convenient wireless network configuration solutions in the different O&M

scenarios, saves the cost of construction. The typical scenarios are as following:

Initial construction configuration





Transmission configuration

Adjustment of the wireless parameters

Cell relationship

The CME has the following attributes:

Offering friendly human-machine exchanging policy

Offering the navigation interface based on the network topology and protocol stack

Simplifying and visualizing the configurations by combining the configuration and

maintenance scenarios of RAN

Meanwhile, the CME has powerful configuration functions, including:

Configuration based on current data area and planned data area

Re-parent Configuration

Configuration wizard

Configuration data check, etc.

5.4.5 iSStar Offering Customized O&M Development Platform

The integrate script star (iSSTAR) of the M2000 system is a script development platform

independently developed by Huawei. It is capable of powerful script development. Based on

the python language, the is STAR has the following advantages:

Supporting the programmable logic control of the MML scripts

Offering compilation and batch execution functions

Providing abundant Huawei Foundation Class (HFC) library

Conveniently expanding the compilation function of scripts

By using the iSSTAR, the carriers can independently develop the scripts of different O&M

functions according to their requirements, scenarios, and working habits. For instance, the

scripts can include the routine check of equipment, real-time supervision of the network,

batch data modifications, etc.

The script compilation is convenient, time-saving, and matches different O&M scenarios. It

greatly improves efficiency and reduces costs.

5.4.6 Software Management and Remote Upgrade Solution to Save OPEX

The software management offered by Huawei can manage the NEs‟ software versions,

patches, licenses, and configuration data. It can also download and activate the software by

batches. The software management offers the GUI to manage the software versions and

patches. Through the tool of graphic Node-B software upgrade wizard, Huawei‟s software

management can download and activate 500 Node-B‟s software at most each time. In

addition, the download and activation of software can be scheduled as scheduling tasks.

The remote upgrade is an important issue of the software management. By using automatic

download and activation software by batches, the complicated grades can be implemented





in easy way. Huawei‟s graphic BSC one-touch upgrade wizard greatly reduces the

complexity of upgrading operation, shortens the time of upgrading and service disruption,

and reduces the risks of upgrading.

The software management and remote upgrade solution has the following advantages:

Implementing the remote upgrade of the mobile network equipment

Saving the time for the operators

Improving working efficiency

Reducing the cost of operation and maintenance

5.5 Inter-working Solution with Existing GSM/GPRS/EDGE System

5.5.1 Inter-working Solution Overview

Spectral efficiency of UMTS is higher than GSM. Hence, operators with high GSM user

penetration rate will consider deploying UMTS network to optimize the total capacity of wireless

network (GSM plus UMTS) within a certain spectrum.

It needs seamless inter-working between existing GSM network and overlay UMTS network to

offer continuous services. In different phases of UMTS deployment, the user distribution of GSM

and UMTS/GSM dual mode is different and the coverage area of UMTS network increases

gradually from the initial phase. It is important to consider different inter-working strategies in

order to achieve operating efficiencies and savings.

Different concerns for operators in UMTS deployment will result in different inter-working

strategies between UMTS and existing GSM network. By considering operating efficiencies, it is

a need to maximize network capacity and to initiate as little as possible of inter-RAT handover. If

the inter-working solution has very little impact on existing GSM system, the investment on

existing GSM network can be reduced, resulting in total cost saving of network deployment.

Based on the above considerations, the proposal of an inter-working solution is recommended

as compared to different solutions.

5.5.2 Inter-working Solutions and Strategy

Camp solution and inter-RAT handover/cell reselection/cell change order solution are two

parts of inter-working solution. There is a need to consider these two solutions respectively.

Once UMTS is introduced to overlay GSM network, there are three possible solutions for

UMTS/GSM dual mode terminal camping. The table below is used to compare these three

solutions in terms of impact on network load, service experience for users and handover.

To fully utilize the capacity of UMTS network, improve the service quality and attract user

with UMTS based services, Huawei recommends „prefer UMTS‟ solution for network camp.





Table 88 Comparison of Three Solutions

Solution Network Load Service Experience Handover

Prefer UMTS

Dual mode UEs camp on UMTS network. It decreases GSM network load and makes full use of UMTS network.

User can request UMTS based services immediately.

Softer/soft handover can be performed within UMTS network. Inter-RAT handover or cell reselection from UMTS to GSM is performed when there is no UMTS coverage.

Prefer GSM

Dual mode UEs camp on GSM network. It increases GSM network load and lessen the use of UMTS network.

Users can request GSM/GPRS/EDGE based services but can‟t request UMTS specific services like VP unless users do network reselection by hand.

Hard handover is performed within GSM network. If inter-RAT from GSM to UMTS is performed, it requires big upgrades in GSM network.

Random

Dual mode UEs in idle mode randomizes between GSM or UMTS. It is difficult to predict the load of each network hence causes a big problem in network optimization and adjustment.

Service experience is based on the camping network.

Handover type is based on the camping network.

For UMTS CS services, there are four possible solutions for inter-RAT handover between

UMTS and GSM. Based on the following analysis, Huawei recommends unidirectional

inter-RAT handover for CS service.

Unidirectional inter-RAT handover from UMTS: Only inter-RAT handover from GSM to

UMTS is performed to offer seamless service. It only needs software patch for GSM system

to support inter-handover from UMTS.

Bidirectional inter-RAT handover: Inter-RAT handover from/to UMTS to/from GSM is

performed to offer seamless service. It requires big changes on GSM BSS and MSC. It

means that operators need to increase investments in GSM network to support

bidirectional inter-RAT handover. It can‟t make total saving in network deployment and

operation.

Non inter-RAT handover: In initial phase, scale of UMTS network is small. Calls will be

dropped once UEs move out of UMTS area if inter-RAT handover is not performed. In

developing/mature phase of UMTS deployment, more and more users will camp on UMTS

network. So, the load of GSM will become less. It can‟t maximize the usage of total network

capacity if no inter-RAT handover to GSM is performed.

Unidirectional inter-RAT handover from GSM: Only inter-RAT handover from UMTS to

GSM is performed. It requires big change in existing GSM elements. And it will have call

drop once out of UMTS coverage (which will often happens in initial phase of UMTS

deployment.).

For UMTS PS service, cell reselection/cell change order procedure is used to keep call

connection once UEs are moving. It only requires GPRS/EDGE support three additional





system information: SI 2ter; SI 3; SI 2quater. Therefore, Huawei recommends bidirectional

cell reselection/cell change order for PS service.

According to the above analysis, Huawei recommends „prefer to use UMTS, unidirectional

handover from UMTS for CS service and bidirectional cell reselection for PS service‟

solution for VMS‟s inter-working between UMTS and existing GSM network. In every

different phase of UMTS deployment, the coverage area of UMTS is different. There will be

impact from the adopting of handover methods to implement the inter-RAT handover.

Considering the small scale UMTS network in initial phase, Huawei recommends coverage

based on inter-RAT handover from UMTS to GSM to keep service continuity. As the UMTS

network develops, load balancing of UMTS and GSM becomes much more critical. Then,

Huawei recommends service and load based inter-RAT handover to maximize the total

network capacity.

The following sub-sections are used to describe the detailed solution of camp and

inter-RAT handover/cell reselection.

1) Camp solution

When an UE is switched on or in roaming, its primary work is to find and connect to a

network to obtain services. This means that this UE needs to camp on one network. If an

UE is switched on in an area covered by UMTS and GSM, Huawei recommends:

Network selection to UMTS network: This can be done by parameter setting (HPLMN with

access technology) in the USIM card. If different PLMNs are used in GSM and UMTS,

UMTS PLMN is set as HPLMN. Else if same PLMN is used for GSM and UMTS, UMTS is

set as higher priority access network. Huawei recommends same PLMN for GSM and

UMTS for it will not require VMS to sign additional roaming agreement for newly adopted

PLMN.

Cell reselection to GSM when there is only GSM coverage (out of UMTS coverage)

Cell reselection to UMTS when there is UMTS coverage

Huawei recommends cell reselection instead of PLMN reselection for UE in idle mode.

PLMN reselection will be performed at least 6 minutes after UE comes back to UMTS

coverage. During this period, UE cannot request for UMTS based services. Cell reselection

can be performed immediately just based on radio measurement.

2) Inter-RAT handover/cell reselection/cell change order solution

Coverage based inter-RAT handover in initial phase

Figure 86 Coverage Based Inter-RAT Handover

In the initial phase of UMTS deployment, GSM network has better coverage than UMTS

network. Not only that, dual mode users are less than GSM only users. Huawei

recommends only coverage based inter-RAT handover is performed. UMTS can support

CS service, PS service, combination services (CS + PS). For different services, Huawei

recommends different handover strategies:

CS services only: Inter-RAT handover to GSM is performed when out of UMTS coverage.

Then, the call is kept in GSM until call is ended even UE moves into UMTS coverage again.

PS services only: Inter-RAT Cell reselection (when UE is not in CELL_DCH state) or

inter-RAT cell change order (when UE is in CELL_DCH state) to GPRS/EDGE is performed

when UE is out of UMTS coverage. When there is UMTS coverage, inter-RAT cell

reselection to UMTS is performed to offer higher data services.

CS service + PS service: For combined services, Huawei recommends to ensure CS

service continuity. The strategy is the same for CS service only. PS service connection will

be kept in the same network as CS service connection.

UE needs to perform cell reselection procedure to return to UMTS when UE is in idle mode

and moved into UMTS coverage.

Figure 87 Service and Load Based Inter-RAT Handover

In developing/mature phase of UMTS deployment, UMTS network has better coverage.

Dual mode users are eventually more than GSM only users. Huawei recommends service

and load based inter-RAT handover. Considering the capability of GSM network, different

handover strategies for different services are required. For details refer to the above figure.

K1/ K2% is the load threshold that is used to initialize service and load based handover.

They can be set to the same or different value which is less than the threshold used to

initialize congestion control. Once cell load exceeds K1/K2%, RNC will initialize

corresponding action. R1/R2 data rate is set to a maximum data rate that

GSM/GPRS/EDGE can support. As per the specification, this functionality shall be

performed under the CN control (CN will set one proper IE in RAB assignment.). Huawei

RNC also supports this functionality by RNC configuration.

If there are combination services, RNC will first consider handover UE with single

connection to GSM and keep UE with combination services in UMTS network because

currently only UMTS network can support combination services.

When there is no UMTS coverage, coverage based on inter-RAT handover will be

performed. The strategy is similar to the one used in initial phase.
