1 Introduction

1.1 Overview

To keep abreast of rapidly advancing mobile communications technologies, mobile operators

are continually seeking partners who provide cutting-edge technologies to set up high-quality,

multimode-enabled, and future-oriented mobile networks efficiently and cost-effectively.

With this aim in mind, Huawei developed 3900 series base stations, which are designed based

on a high-performance platform and use an optimized hardware and software architecture.

These base stations can work in multiple modes due to their cutting-edge modular design.

They also have broad bandwidth and are eco-friendly and easily upgradeable.

Specifically, 3900 series base stations use the newly developed power amplifiers (PAs),

provide the temperature control function, and employ the innovated power saving technique.

In addition, by adopting the cutting-edge modular design, 3900 series base stations use

multimode modules with different appearances to meet requirements in various conditions.

Thanks to all these merits of 3900 series base stations, mobile operators can set up

high-quality, multimode-enabled, and future-oriented mobile networks and capital

expenditure (CAPEX) on site acquisition, capacity expansion, and environment protection can

be greatly reduced.

Different types of 3900 series base stations can be delivered on request because the newly

designed modules and auxiliary devices can be flexibly combined and configured.

Figure 1-1 shows the different types of 3900 series base stations.

Figure 1-1 3900 series base station types

This document focuses on the BTS3900, BTS3900A, BTS3900L, BTS3900AL, BTS3900C, and DBS3900 only. For a description of the other types of 3900 series base stations, see the product description for the base station in question.

1.2 Benefits

Smooth Evolution

Upgrading from Global System for Mobile Communications (GSM) to Universal Mobile

Telecommunications System (UMTS) and then to Long Term Evolution (LTE) is easy thanks

to the following factors:

In SRAN7.0 or earlier: A BBU3900 is equipped with different boards, among which

some work in one mode and the others work in another mode. The BBU3900 can process

services for both of these modes. With two BBUs, the triple-mode application can be achieved.




3

In SRAN8.0: The GSM, UMTS, and LTE modes share one BBU3900.

Developed with the Software-defined radio (SDR) technique, RF modules can work in

GU, GL, or UL dual-mode. SDR RF modules and single-mode RF modules can be installed in the same cabinet to achieve multimode and multi-band applications.

Energy-Efficient and Eco-Friendly

Thanks to their small size and modular design, PAs do not take up much space in the

equipment room and power resources are saved with the new power-saving technique.

The following measures also help save energy:

RF channels are blocked and PA voltage is adjusted if the downlink load reaches a preset threshold.

The power supply unit (PSU) shuts down if the base station is provided with sufficient

power.

The temperature control function controls board temperature, outdoor cabinets use a direct ventilation system, and RRUs adopt the natural heat dissipation mechanism.

Low CAPEX

In terms of the CAPEX for devices

3900 series base stations use one set of multimode devices to support multimode applications.

An external reference clock and transmission resources are shared across modes on a

3900 series base station, reducing the CAPEX for transmission resources and external clock sources.

Various types of radio frequency (RF) modules are introduced, for example,

software-defined radio (SDR) RF modules supporting antenna-sharing, dual-transmitter

RF modules supporting the multiple-input multiple-output (MIMO) technology, and

single-transmitter RF modules with high power and large capacity.

The GU or GL refarming feature is introduced to facilitate the evolution from GSM to UMTS, and LTE and eventually to save the CAPEX for evolution.

In terms of operation and maintenance (O&M), different modes on a single 3900 series base

station share the same auxiliary devices and are managed by the same network management

system, which greatly reduces O&M costs. The O&M manpower required is also reduced,

because 3900 series base stations are easy to install and maintain and it is easy to expand their

capacities.

High Transmission Reliability and High Board Performance

The following features are introduced to ensure high transmission reliability and high board

performance:

Support for the Huawei SingleBTS platform

Support for Co-Radio Resource Management (Co-RRM), Co-Transmission Resource

Management (Co-TRM), Co-Operation and Management (Co-OAM), and Co-Radio Network Plan&Radio Network Optimization (Co-RNP&RNO)

Support for route backup. Transmission paths can be switched over to protect high-priority service data.

Support for the backup of important boards and power modules

2.2 Basic Modules 3900 series base stations have a modular design. The basic modules are the baseband unit

(BBU) and radio frequency module which includes radio frequency unit (RFU), remote radio

unit (RRU), and active antenna system (AAS). The BBU uses common public radio interfaces

(CPRIs) and electrical or optical cables to communicate with the RFUs or RRUs.

2.2.1 BBU3900

As a baseband control unit, a BBU3900 provides the following functions:

Centrally manages the entire base station, including operation and maintenance,

signaling processing, and the system clock.

Processes uplink and downlink baseband signals.

Provides physical ports, which are used to connect the base station to the transport

network for information exchange; a maintenance channel, which is used to connect the

BBU3900 to the operation and maintenance center (OMC); CPRI ports for

communication with RF modules; and ports for communication with environment monitoring devices.

Figure 2-1 shows the slot layout of a BBU3900.

Figure 2-1 Slot layout of a BBU3900

2.2.2 RFU

RFUs can be used in a macro base station. The RFU modulates and demodulates baseband

and RF signals, processes data, amplifies power, and conducts VSWR detection.

RFUs fall into the following three types:

Multimode modules: MRFU, MRFUd, MRFUe

GSM modules: GRFU, DRFU

UMTS modules: WRFU, WRFUa, WRFUd, WRFUe

LTE modules: CRFUd, CRFUe, LRFU, LRFUe

Figure 2-2 shows the appearance of an RFU.

2.8 DBS3900 The DBS3900 facilitates site acquisition as well as network planning and optimization, and

reduces network deployment time. It enables operators to efficiently deploy a

high-performance GSM/UMTS/LTE network with a low total cost of ownership (TCO) by

minimizing investment in electricity, space, and manpower.

The DBS3900 consists of BBU3900s and RRUs. The BBU3900 is characterized by its small

footprint, easy installation, and low power consumption. Therefore, the BBU3900 can be

easily installed in a spare space at an existing site. The RRU is also compact and light. It can

be installed close to an antenna to reduce feeder loss and to improve system coverage.

Typical installation scenario 1 for the DBS3900

DBS3900 outdoor site: if the AC power supply is provided, an APM30H

(Ver.B)/APM30H (Ver.C)/APM30H (Ver.D) is used; if +24 V DC power supply is

provided, an APM30H (Ver.B) is used; if –48 V DC power supply is provided, a TMC11H (Ver.B)/TMC11H (Ver.C)/TMC11H (Ver.D) is used. See Figure 2-22.

Figure 2-22 Typical installation scenario 1 for the DBS3900

DBS3900 outdoor site that has insufficient space: if the AC power supply is provided, an

OMB (Ver.C) AC cabinet is used; if –48 V DC power supply is provided, an OMB (Ver.C) DC cabinet is used. See Figure 2-23.



DBS3900 indoor site: if RRUs are installed remotely and the BBU and power distribution unit are installed indoors on a wall, an IMB03 is used. See Figure 2-24.

DBS3900 indoor site: if RRUs must be installed in centralized mode, the L-shaped stand can be used. See Figure 2-24.




31



DBS3900 indoor site: if RRUs are installed remotely, and the BBU and power

distribution unit are installed on a support on the floor of a room, a 19-inch open rack is used. See Figure 2-25.




32


If RRUs need to be installed on the outdoor ground in centralized mode, an OPS-06 is used.

If the distance between the RRUs and BBU is too long, and no back power is required, AC

RRUs are used.AC RRUs are powered by the AC power equipment supplied by the customer.

When the AC RRUs are installed outdoors, each AC RRU needs to be configured with an

SPD, an AC surge protector.

NOTE *: In this scenario, the APM cabinet connected to RRUs must be separately configured.

2.10 LampSite solution The RHUB3908, which is 1 U in height, can be installed in a cabinet, rack, shelf, or on a wall.

The pRRU3901 can be installed on a wall or ceiling. In the LampSite solution, the base

station comprises the baseband unit (BBU), pico remote radio unit (pRRU), and RRU HUB

(RHUB). These modules can be flexibly combined to meet different scenario requirements.

Like the DBS3900, the LampSite uses the same type of BBU.

The RHUB3908 and pRRU3901 are compact and light, and therefore they can be installed

anywhere indoors. The RHUB3908, which is 1 U in height, can be installed in a cabinet, rack,

shelf, or on a wall. The pRRU3901 can be installed on a wall or ceiling.

In office buildings, BBUs are installed in an equipment room, and RHUBs and pRRUs are

installed in the office areas, as shown in Figure 2-48.

3900 Series Base Station Product Description 3 Logical Structure



52

3 Logical Structure

From the perspective of logical structure, 3900 series base stations consist of control

subsystem, transport subsystem, baseband subsystem, RF subsystem, clock subsystem, and

power and environment monitoring subsystem. Figure 3-1 shows the logical structure of 3900

series base stations.

Figure 3-1 Logical structure of 3900 series base stations

Control subsystem (BTS CTL subsystem): controls and manages resources in a base

station. It provides the management plane interface between the base station and the

OMC, the control plane interface between the base station and other NEs, and the interface for controlling and negotiating common devices in a multimode base station.

Transport subsystem (BTS TRP subsystem): forwards data between the transport

network and the base station. It provides physical ports between the base station and the transport network and the user plane interface between the base station and other NEs.

3900 Series Base Station Product Description 3 Logical Structure



53

Baseband subsystem (BTS BB subsystem): processes uplink and downlink baseband

data.

RF subsystem (BTS RF subsystem): transmits and receives radio signals. It provides ports for data transmission between the antenna system and the base station.

Clock subsystem (BTS TAS subsystem): synchronizes the base station clock with

external clock sources. It provides ports between the base station and external clock

sources.

Power and environment monitoring subsystem (BTS MPE subsystem): provides power

supply, dissipates heat, and monitors the environment for a base station. It provides ports between the base station and site devices.

4 Operation and Maintenance

4.1 Overview

3900 series base stations are managed by an O&M system using either MML commands or a

graphical user interface (GUI). This system is hardware-independent and provides

comprehensive functions to meet users' various O&M requirements.

4.2 O&M System Structure Figure 4-1 shows the O&M system structure for 3900 series base stations with software of

SRAN7.0 or earlier.

For such base stations, the O&M system consists of the following:

GBTS SMT: locally manages one GBTS. O&M personnel use network cables to connect

the PC running the GBTS SMT to the O&M port of the GBTS that the GBTS SMT will

manage.

BSC LMT: remotely manages multiple GBTSs. O&M personnel use the BSC LMT to remotely manage multiple GBTSs in a centralized manner.

NodeB LMT: manages one NodeB. O&M personnel can use network cables to connect

the PC running the NodeB LMT to the O&M port of the NodeB that the NodeB LMT

will manage. Alternatively, O&M personnel can remotely manage a NodeB through O&M channels by connecting the PC running the NodeB LMT to the NodeB.

eNodeB LMT: manages one eNodeB. O&M personnel can use network cables to connect

the PC running the eNodeB LMT to the O&M port of the eNodeB that the eNodeB LMT

will manage. Alternatively, O&M personnel can remotely manage an eNodeB through

O&M channels by connecting the PC running the eNodeB LMT to the eNodeB.
