1 Introduction 1.1 Positioning

This document describes HUAWEI USN9810 V900R011.

The Huawei-proprietary USN9810 is a unified service node that can be deployed in 2.5G general packet radio service (GPRS) systems, 3G universal mobile telecommunications systems (UMTSs), or evolved packet core (EPC) systems. The USN9810 is deployed at the EPC and can provide the functionalities of the serving GPRS support node (SGSN), mobility management entity (MME), or any combination of them. It is maintained as a single piece of equipment.

1.1.1 3GPP System Evolution This section describes the evolution of the EPC system.

1. Introduction to existing networks With the evolution of the radio technologies, existing networks have evolved from the 2G global system for mobile communications (GSM) to the 2.5G GPRS and lastly the 3G UMTS. This evolution has allowed mobile communications to achieve wide area coverage, high-speed radio data transmission, and integration with the Internet. The result is that the consumer can enjoy diversified services like voice, data, and video applications and "any time, any place" communication delivered in a personalized fashion. Currently, with the robust development of services and diversification of requirements, the 3G UMTS architecture is hindered by inherent limitations: Insufficient support for packet switched (PS) domain network services. Generally, the

3G UMTS system is capable of supporting only non-real time services and depends on the circuit switched (CS) domain to bear voice services. This results in separate network operations for PS and CS, which hinders centralized network maintenance and management and increases OM expenditures.

Low efficiency in routing and forwarding data due to excessive network layers. Therefore, network performance needs to be improved.

Incapable of supporting multiple radio access systems. The development of service terminals in processing capabilities and radio access capabilities provides an impetus for the integration of multiple radio access technologies.




2. Introduction to EPC networks To maintain a competitive edge in future networks, the 3rd Generation Partnership Project (3GPP) began to research the implications and long-term evolution of 3G technology-E3G technology. E3G refers to the enhanced 3G system, which has the following features: The technology for the air interface in E3G is LTE. The core network evolution program of the LTE project is SAE, also known as the

EPC. The 3GPP EPC project is working on a long-term program to explore key technologies in the next 10 years. According to the 3GPP evolution design, the EPC system provides the following features: Overall packetization of the network architecture: The all-IP network contains only

the PS. Voice services are jointly provided by the PS and the IP multimedia subsystem (IMS), enhancing the network efficiency and performance.

Delayered network architecture: The network architecture becomes simpler so that networks can be deployed more easily and data transmission delay is greatly reduced. The S-GW and P-GW may be implemented in one physical node, delayering the network.

Support for multiple access technologies: The EPC system supports interworking with the existing 3GPP system. In addition, it supports access of users in non-3GPP networks and provides roaming and handover between the 3GPP and non-3GPP networks for users.

High data transmission rate: The peak rate of the downlink traffic reaches 100 Mbit/s and the peak rate of the uplink traffic reaches 50 Mbit/s.

Fast deployment: Thanks to the simplified architecture, networks can be deployed rapidly to adapt to the requirements of the changing services.

Enhanced real-time services: The EPC system supports real-time services and reduces the setup time for service connections.

Figure 1-1 shows the evolution of the network architecture in the 3GPP standard.

The EPC network is designed for high-speed mobile packet data services. The network architecture is greatly simplified. Compared with the earlier versions, the architecture is optimized in the following ways:

The LTE base stations are directly connected to the EPS core network. The previously independent base station controller (BSC) functions are integrated into the eNodeB.

The PS domain is restructured as follows:




The signaling plane and forwarding plane of the SGSN are separated from each other. The signaling function of the SGSN is implemented by the MME, and the forwarding function of the SGSN is implemented by the S-GW.

In a version earlier than USN9810 V900R011C00, an SGSN is called a Gn/Gp SGSN. In a version later than USN9810 V900R011C00, an SGSN is called an S4 SGSN. The Gn/Gp SGSN inherits the SGSN functions of the 2G/3G network. The GGSN can be connected to the GERAN or UTRAN through the Gn/Gp SGSN. The S4 SGSN is the upgraded version of Gn/Gp SGSN. The EPC can be connected to the GERAN or UTRAN through the S4 SGSN, which supports the users' switchover between the GERAN/UTRAN and E-UTRAN. The functions of the GGSN are provided by the P-GW. The S-GW and P-GW may be implemented in one physical node, delayering the

network. The network converges with the non-3GPP networks such as CDMA2000 high rate

packet data (HRPD) network, providing the interworking for various radio access technologies as shown in Figure 1-2.

1.1.2 LTE/EPC Solution In response to the latest evolution of the network architecture, Huawei provides the corresponding LTE/EPC solution that supports different network elements (NEs) such as the MME, S-GW, and P-GW to keep up with the development trends of multi-service convergence and multi-access convergence.

The USN9810 is deployed at the EPC and can provide the functionalities of the SGSN, MME, or any combination of them. It is maintained as a single piece of equipment.

The LTE/EPC network consists of the following items:

UE: It is a mobile user device, initiating and receiving calls through the air interface. E-UTRAN: It implements all functions related to the radio access. EPC: It is the core network, consisting of the MME, S-GW, P-GW, and HSS and

connecting the external PDNs such as the Internet.

1.1.3 NE Introduction

As specified in 3GPP 23.401, the functions of the NEs in the LTE/EPC solution are described as follows:

E-UTRAN The E-UTRAN implements all functions related to the radio access to the LTE/EPC network, including:

Management and establishment of radio resources Header compression and user plane ciphering MME selection when no route to an MME can be determined from the information

provided by the UE




UL bearer level rate enforcement based on UE-AMBR by means of uplink scheduling and MBR

DL bearer level rate enforcement based on UE-AMBR UL and DL bearer level admission control Transport level packet marking in the uplink, for example, setting the DiffServ Code

Point, based on the QoS Class Identifier (QCI) of the associated EPS bearer

MME The MME is responsible for mobility management in the control plane, including management of the user contexts and mobile status, and assignment of temporary identifiers. The functions of the MME include:

NAS signaling NAS signaling security Inter CN node signaling for mobility between 3GPP access networks (terminating S3) UE reachability in ECM-IDLE state (including control and execution of paging

retransmission) Tracking Area list management P-GW and S-GW selection MME selection for handovers with MME change Roaming (S6a towards home HSS) Authentication Bearer management functions including dedicated bearer establishment

S-GW The S-GW is the anchor point in the user plane between different access networks. It can shield interfaces within the 3GPP network towards different access networks. The S-GW is the gateway that terminates the interface towards E-UTRAN.

The functions of the S-GW include:

The local mobility anchor point for inter-eNodeB handover Assist the eNodeB reordering function during inter-eNodeB handover by sending one or

more "end marker" packets to the source eNodeB immediately after switching the path Mobility anchoring for inter-3GPP mobility (terminating S4 and relaying the traffic

between 2G/3G system and P-GW) ECM-IDLE mode downlink packet buffering and initiation of network triggered service

request procedure Lawful interception Packet routing and forwarding Transport level packet marking in the uplink and the downlink (DSCP) Accounting on user and QCI granularity for inter-operator charging




P-GW The P-GW is the anchor point in the user plane between the 3GPP access networks and non-3GPP access networks. The P-GW is the gateway that terminates the SGi interface towards the PDN.

DHCPv4 (server and client) and DHCPv6 (server) functions UL and DL bearer binding UL bearer binding verification

SGSN The LTE/EPC architecture supports the Gn/Gp SGSN and S4 SGSN.

The Gn/Gp SGSN inherits the SGSN functions of the 2G/3G network. The GGSN can be connected to the GERAN or UTRAN through the Gn/Gp SGSN. The S4 SGSN is the upgraded version of Gn/Gp SGSN. The EPC can be connected to the GERAN or UTRAN through the S4 SGSN, which supports the users' switchover between the GERAN/UTRAN and E-UTRAN.

The SGSN is an NE used to provide the packet data services. The main function of the SGSN is to forward the IP packets from/to the UEs in its own SGSN service area. The functions of the SGSN include:

Routing and forwarding data packets from/to all mobile users in its own SGSN area Encryption and authentication Session management Mobility management Logical link management Bill generation and export for collecting usage information of radio resources




HSS The home subscriber server (HSS) stores all subscriber data related to services provided by LTE/EPC networks.

CG As a device on the LTE/EPC network, the CG collects, and pre-processes the charging history records (CDRs) generated by the GGSN, S-GW and P-GW. The CG also provides an interface to the billing center. When an LTE/EPC user accesses the Internet, several NEs generate CDRs. Each NE may generate several CDRs. The CG pre-processes the CDRs, and then sends them to the billing center. Thus, the work load of the billing center is reduced. If the CG is applied in the network, the GGSN, S-GW and P-GW do not need to provide interfaces to the billing center.

PCRF PCRF is the policy and charging control element.

In a non-roaming scenario, there is only a single PCRF in the Home Public Land Mobile Network (HPLMN) associated with one UE's IP-CAN session. The PCRF terminates the Rx interface and the Gx interface.

In a roaming scenario with local breakout of traffic there may be two PCRFs associated with one UE's IP-CAN session:

H-PCRF that resides within the H-PLMN V-PCRF that resides within the V-PLMN

The functions of the H-PCRF include:

Terminating the Rx interface for home network services Terminating the S9 interface for roaming with local breakout Associating the sessions established over the multiple interfaces (S9, Rx), for the same

UE's IP-CAN session Terminating the Gx interface for home network services in the roaming scenario

The functions of the V-PCRF include:

Terminating the Gx and S9 interfaces for roaming with local breakout Terminating Rx for roaming with local breakout and visited operator's application

function

AAA Server The AAA server is used for authentication, authorization, and accounting. It complies with the Remote Authentication Dial in User Service (RADIUS) protocol. The AAA server can also be deployed on other networks in addition to LTE/EPC networks.

3GPP AAA Server The 3GPP AAA server is used for mobility related authentication for the switchover to non-3GPP networks and is used to provide static QoS information for users that access the UGW9811 through non-3GPP access networks.




DNS There are two types of DNS on the LTE/EPC network:

DNS located between the P-GW and the PDN It is used to resolve the domain name of the PDN, equivalent to a common DNS on the Internet.

DNS located on the LTE/EPC core network When the UE requests to access an external network for packet services, the MME requests the DNS to resolve the domain name according to the access point name (APN). After the IP address of the corresponding P-GW is obtained, a transmission channel can be set up between the UE and P-GW. In mobility management procedures, such as attach and tracking area update (TAU), a DNS is used for selecting the peer MME/SGSN.

The DNS can also be deployed on other networks in addition to GPRS/UMTS networks.

1.2 Introduction to the USN9810

The USN9810 is an MME device developed by Huawei. The USN9810 features multiple access standards and multiple logical product types. It supports access to the GPRS, UMTS or LTE and exists in the form of the SGSN, MME or their combined logical type.

Large Capacity and High Integration

The USN9810 supports a maximum of 12 million 4G subscribers attached at the same time. In the case of full configuration, only two cabinets and six subracks are required.

The USN9810 supports a maximum of 12 million 2.5G or 3G subscribers attached and 2.2 million Packet Data Protocol (PDP) context activated at the same time. In the case of full configuration, only three cabinets and eight subracks are required.

The USN9810 uses a high-speed forwarding processor to forward the data on the user plane, which improves the processing efficiency and integration of the system. The USN9810 configured for 2.5G subscribers supports data forwarding at a maximum of 3.6 Gbit/s. The USN9810 configured for 3G subscribers supports data forwarding at a maximum of 20 Gbit/s.

Advanced ATCA Platform

Advanced Telecommunications Computing Architecture (ATCA) is a hardware standard. It is the name of the architecture standard for the hardware platform rather than the name of a specific product.

Developed on the basis of the CPCI standard, ATCA meets new requirements of the telecom industry. Compared with CPCI, ATCA possesses the following features:

Providing powerful processing capability, that is, providing sufficient bandwidth, faster calling rate and loading rate of the processor, and improved running efficiency to meet the current and future requirements.

Enhancing the reliability of the system by separating the management platform, the control plane, and the service plane, all with a point-to-point structure.




Providing large space in boards. The hot-swappable advanced mezzanine card (AMC) will be supported in the future. Thus, the embedded application, server application, and digital signal processing (DSP) array can be flexibly combined to meet the application requirements for different capacities.

1. Hardware Platform

The USN9810 V900R001 uses the internal open standards telecom architecture (OSTA 2.0) platform of Huawei. Based on the ATCA technology, OSTA 2.0 provides high rate, high reliability, and high scalability.

The OSTA 2.0 hardware platform stipulates a series of specifications related to boards and software for the next generation telecom devices. Based on the ATCA standard architecture and conforming to the network equipment building system (NEBS) and European telecommunications standards institute (ETSI) standards, the platform has the following features:

High rate The high-speed serial data link and switched structure are used. Thus, the data exchange bandwidth intra-subrack can reach 2.5 Tbit/s.

High reliability All boards and subboards are hot swappable. In addition, redundancy is implemented on all key components, such as power supply, fan, management module, and board of each type. Thus, the reliability of the system reaches 99.999%.

High scalability The USN9810 supports the addition of the interfaces on the ATCA board and cascading between subracks through the interface board within a subrack.

Efficient management The standard management bus is used, which can manage any part in the system.

2. Software Platform

The USN9810 V900R001 uses the embedded software platform, namely, carrier grade platform (CGP), which is universally used by the core network products of Huawei. The CGP has the features such as cross-hardware platform, cross-operating system, and easy maintenance.

Cross-hardware platform A uniform interface of the hardware platform is provided, which implements the operation of upper-layer applications on different hardware platforms. Thus, the hardware management is independent of the hardware platform.

Cross-operating system Different interfaces of the operating system at the lower layer are shielded. Instead, a uniform virtual operating system application programming interface (VOS API) is provided for upper-layer applications.

Easy maintenance The implementation mechanisms of the functions such as operation and maintenance, alarm management, performance measurement, call and signaling tracing, data backup, board switchover, and online loading are provided for upper-layer applications.




Easy Operation and Maintenance

The operation and maintenance (OM) system of the USN9810 has the following features: Flexible OM methods

The OM system can be flexibly built according to the network structure and customer requirements. Multiple maintenance interfaces are supported, including the interfaces to the local maintenance terminal (LMT) and the Huawei centralized network management system iManager M2000. Through the Common Object Request Broker Architecture (CORBA) interface provided by the iManager M2000, flexible network management can be implemented.

Maintenance interface combining MML and GUI The interface is characteristic of easy and quick operations provided by man-machine language (MML) in addition to vivid display and easy memory provided by graphic user interface (GUI).

Powerful signaling trace The USN9810 provides the S1-AP, S11 and Gn/Gp interfaces for signaling trace. In addition, it supports hierarchical signaling trace according to the protocol. The USN9810 can also interpret and filter tracing messages.

Online software patching Software problems can be solved online without impacting services. In addition, you can perform remote and rollback operations.

High Reliability

The USN9810 is highly reliable because of the following features:

Backup of important data The USN9810 automatically backs up important data, such as the configuration data, performance data, and operation logs.

Operation security management Different management privileges are assigned to different users. During the user login, the USN9810 checks the user identity. After the user login, the USN9810 maintains the complete operation to ensure system security.

Hardware redundancy design All critical boards are configured in the 1+1 backup to ensure the high reliability of the system.

Fault prevention The USN9810 provides protection mechanisms to avoid the following system faults: System power off Maloperation on the system power switch Lightning surge on the system power High voltage and low voltage Short circuit of power supply Current surge and high voltage on the power supply and interfaces

System overload control




In the case of center processing unit (CPU) overload or resource congestion, the USN9810 adjusts the traffic smoothly to avoid system down.

Board lock and unlock, process lock and unlock The board and process lock function stops access to new services as required and gradually removes the existing services within a certain period. The board and process unlock function, however, provides access to new services.




2 Architecture 2.1 Overview

The system structure of the USN9810 includes hardware structure and software structure.

2.2 Hardware Architecture

The USN9810 uses the Huawei OSTA 2.0 hardware platform, which is based on ATCA. The physical structure of the platform consists of cabinets, subracks, and boards.

Introduction to the Cabinet

As a cabinet-type device, the USN9810 uses the Huawei N68E-22 cabinet. The available space of the cabinet is 46 U (1 U = 44.45 mm = 1.75 inch). The cabinet, composed of the power distribution frame (PDF), OSTA 2.0 subrack, cabling frame, filler panel, rack, and slide rail, enables the internal modules to be flexibly configured.

The OMU board is configured in the basic subrack. In the basic subrack, the back board of the SWU board is the TMI board. In the service subrack, the back board of the SWU board is the TSI board.

The board area of a subrack has 14 slots at the front and rear sides respectively. Boards can be inserted from both the front side and the rear side of the subrack. The front boards, switching




unit (SWU) boards and the corresponding back boards, time master interface (TMI)/time slave interface (TSI) boards occupy slots 6 and 7. Other slots, namely, slots 0 to 5 and slots 8 to 13 are the slots for universal services.

Two subrack management unit (SMU) boards and two subrack data manage (SDM) boards exist at the bottom of the subrack. The SMU board and the SDM board are mutually inserted from the front side and the rear side. The SMU board is located at the front side of the subrack and the SDM board is located at the rear side of the subrack.

Host Software

The host software runs on different boards. It implements functions such as signaling access and processing, service control, resource management, and charging information generation. In response to specific commands, the host software also performs the following operations such as data management, device management, alarm management, performance statistics, and signaling trace on the host in cooperation with the BAM software.

The host software adopts a hierarchical and modular design. From bottom to top, its components are the operating system, middleware, and various applications.

1. Operating System

The operating system of the host software is Linux, which is a real-time operating system.

2. Middleware

The middleware technology (DOPRA) is applied to the operating system and applications of the USN9810. Thus, the upper-layer service software is irrelevant to the lower-layer operating system.

The middleware facilitates the migration of software functions between different platforms. Thus, new and stable product versions are released quickly as the service software is rarely changed.

3. Applications

The application is the functional part of the USN9810 software. Loaded with different applications, boards can provide different functions. The USN9810 applications can be classified into the following types:

Signaling bearer software: Implements the access of broadband and narrowband signaling and processing of the lower-layer protocols

Service processing software: Performs signaling processing, session management, mobility management, and resource management

Database software: Manages device data and dynamic subscriber data System support software: Implements system management and device interconnection




OM software: Receives the operation commands from the OMU and reports the command results to the OMU

BAM Software

The BAM software runs on the OMU, LMT, and Web UI. Along with the host software, it provides the man-machine interface, which enables the maintenance personnel to implement the following functions: data management, device management, alarm management, performance statistics, signaling trace, and CDR management.

The BAM software adopts the client/server model. It consists of the OMU server software, LMT software, and Web UI software. The OMU server software is installed on the OMU. The LMT software and Web UI software is installed on the client, namely, a PC.

1. OMU server software

The OMU server software runs on the OMU board. As a combination of the communication server and the database server, the OMU server software forwards OM commands from different workstations to the host and sends responses or command results to the corresponding workstations. The OMU server software serves as the essential unit of the OAM software.

The OMU server software runs on the Linux operating system and uses the Oracle as the database platform. It provides functions of the terminal OAM software through multiple parallel service processes, such as maintenance process, data management process, alarm process, and performance statistical process. Figure 2-7 shows the relation between the OMU server software, operating system, and database platform.

4 Operation and Maintenance The USN9810 offers abundant services and functions, and meets the requirements of multiple networks and operations.

4.1 Overview

This part briefs the operation and maintenance system in the network, interfaces, and functions.

4.2 Benefits

The operation and maintenance (O&M) system of the USN9810 has the following features: Flexible O&M methods

The O&M system can be flexibly built according to the network structure and customer requirements. Multiple maintenance interfaces are supported, including the interfaces to the local maintenance terminal (LMT), the Huawei centralized network management system iManager M2000. Through the Common Object Request Broker Architecture (CORBA) interface provided by the iManager M2000, more network management requirements can be fulfilled.

Friendly user interfaces The USN9810 provides O&M interfaces that combines the merits of both man-machine language (MML) and graphic user interface (GUI).

Web UI-based maintenance operation and performance browse The Web UI-based maintenance operation and performance browse are added. That is, certain maintenance operations and performance browse are implemented on the Web.

Powerful signaling tracing The USN9810 provides interface tracing, subscriber tracing, and entire-process tracing. It is a powerful tool for equipment maintenance. Interface tracing tasks can be performed on interfaces such as the Gb, Iu, Gn, Gp, Gs, Gd, Gr, Ga, S1-MME, S6a, S10, and S11 interface or performed for the protocols such as SCCP, MTP3B, SAAL, DIAMETER, and S1AP.




The subscriber tracing traces the messages of the specified IMSI or mobile station international ISDN number (MSISDN). The entire-process tracing traces how the packets with specified characteristics are transmitted between modules and calculate the number of packets of the same characteristics processed in each module. This is used to locate the problems during packet transmission such as protocol handling errors, packet loss, delay, packet fault, or sequence disorder. Operators can save the trace results to handle any queries in the future.

Configuration rollback The configuration rollback in batches is supported. Only one rollback point can be set.

One-key upgrade and installation Software patching in function level

Through online software patching, software errors can be solved without interrupting services. The USN9810 also supports remote patching and version fallback.

4 Input jitter tolerance

For details, see Figure 5-1.




Minimum accuracy: maximum deviation value of nominal frequency in a long period (20 years) without external frequency benchmark, that is, the clock is in free running state. Maximum frequency deviation: a maximum value of the clock's relative frequency change in a UI during a consecutive operation process. Pull-in range: maximum frequency bandwidth of the input signal locked by a clock MRTIE: The MRTIE extracts the offset that appears in measurements performed with local reference clocks.

Figure 5-1 Maximum permissible lower limit of input jitter and wander

When the jitter frequency of an input frequency is 1 kHz and the amplitude is more than 1.5 UI, you can infer that the input signal meets the requirements if the system operates normally.

UI refers to the unit of time interval. One UI equals the reciprocal of the frequency of the digital signal. For example, the UI of the 2.048 Mbit/s signal is 488 ns.
