Figure 1-1 BSC6000 cabinet

The BSC6000 supports the star, chain, tree, and ring topologies. Figure 1-2 shows the role of

the BSC6000 in the GSM-R network.


5/26




Page 5 of 26

Figure 1-2 Role of the BSC6000 in the network

The interfaces between the BSC6000 and each network element (NE) in the GSM-R networkare as follows:

Um: interface between the BTS and the MS

Abis: interface between the BSC6000 and the BTS

A: interface between the BSC6000 and the Mobile Switching Center (MSC) or MediaGateway (MGW)

Gb: interface between the BSC6000 and the Serving GPRS Support Node (SGSN)

The A, Um, and Gb interfaces are standardized interfaces, through which equipment from

different vendors can be interconnected.

In a GSM-R network, the BSC6000 is responsible for the following functions:

Radio resource management

Base station management

Power control

Handover management

1.2 Benefits

High Network Reliability

The BSC6000 supports the following network reliability features:

Duo-location BSC

Single frequency double coverage

BBU redundancy


6/26




Page 6 of 26

Single frequency TRX redundancy

With these reliability features, single pints of failure are avoided in the BSS, thus improving

network reliability and ensuring continuity of network operations in the case of NE outage.

Duo-location BSCThe duo-location BSC feature enables two BSCs working in active/standby mode to connect

to the MSC/SGSN and the BTS at the same time. In normal cases, the active BSCcommunicates with the MSC/SGSN and the BTS to provide services, and the standby BSC

communicates with the MSC/SGSN and the BTS only to establish physical connections.When the active BSC is faulty, the standby BSC automatically takes over.

Single frequency double coverage

The single frequency double coverage feature enables two BTSs working in active/standbymode to cover the same area. In addition, only one of the BTSs is working at any specific

time. The two BTSs use identical frequencies. In normal cases, the active BTS works properly,whereas the standby BTS works but does not transmit power. When the active BTS is faulty,

the BSC triggers the switchover between the active BTS and the standby BTS. Specifically,the active BTS is downgraded to standby, whereas the standby BTS is upgraded to active.

This reliability feature ensures a fully backed-up radio coverage while using only the

frequencies necessary for a single layer coverage.

BBU redundancy

The BBU redundancy feature enables an RRU to establish physical connections with two

BBUs working in active/standby mode at the same time. In normal cases, an RRUcommunicates with only the active BBU, and also supports the switchover between CPRI

ports. When the active BBU is faulty, the BSC triggers the switchover between the activeBBU and the standby BBU during which the CPRI ports are also switched over. In this

manner, the RRU communicates with the standby BBU.

Single frequency TRX redundancy

The single frequency TRX redundancy feature enables a BTS to be configured with a standby

TRX that shares the same frequencies with an active TRX. When the active TRX is faulty, thestandby TRX is automatically activated to take over as the active TRX, thus improving

network availability and ensuring continued network even in the case of a TRX failure

High Integration and Low Cost

The BSC6000 features large capacity and high integration. A single BSC6000 cabinetsupports a maximum of 2048 TRXs, which meets the requirements for the GSM-R network

along tracks. In addition, the BSC6000 takes a small space and reduces power consumption.

Easy Configuration and Convenient Maintenance

The BSC6000 has a small number of board types. In addition to transmission boards, theBSC6000 cabinet houses network switching boards, signaling processing boards, and service

processing boards. Simplifying board types reduces the maintenance cost. The interface boards and service boards, not bound together, are flexible in configuration and easy to

maintain and expand.

2 Architecture2.1 Overview

The BSC6000 has a modular design. It enhances resource utilization and system reliability byfully interconnecting subracks and applying distributed resource pools to manage the service

processing units. The backplane is universal and every slot is common to different types of boards to perform various functions. In this way, the universality and evolution of the

hardware platform are improved.

2.2 Hardware Architecture

2.2.1 Cabinets

The BSC6000 uses a Huawei's standard N68E-22 cabinet. The design complies with theIEC60297 and IEEE standards.

A BSC6000 cabinet is made up of subracks. There are three types o f subracks:

Main Processing Subrack (MPS)

Extended Processing Subrack (EPS)

Transcoder Subrack (TCS)

A BSC cabinet (also known as rack) can be of three different types, depending on the

subracks with which it is populated:

Cabinet type 1: Main Processing Rack (MPR)

Cabinet type 2: Extended Processing Rack (EPR)

Cabinet type 3: Transcoder Rack (TCR)

Each cabinet (rack) type has to follow configuration rules in terms of the number and type ofsubracks it contains. If the number of subracks in a cabinet is less than three, the subracks

should be configured from the bottom of the cabinet upwards, as shown in Figure 2-1.

2.2.2 Subracks

In compliance with the IEC60297 standard, the BSC6000 subrack has a standard width of 19

inches. The height of each subrack is 12 U. The boards are installed on the front and rear sides

of the backplane, which is positioned in the center of the subrack.


9/26




Page 9 of 26

Each subrack provides 28 slots. The slots on the front of the subrack are numbered from 0 to

13, and those on the rear are numbered from 14 to 27.

Figure 2-2 shows the front and rear view of the subrack.

Figure 2-2

Front view (left) and rear view (right) of the subrack

As mentioned in the preceding sections, the BSC6000 subrack is classified into the MPS, EPS,

and TCS. The MPS and the EPS subracks collectively form the basic module (BM); the TCSsubracks collectively form the transcoder (TC).

Table 2-2 Functions of BSC6000 subracks

Subrack Quantity Function

MPS 1 Performs centralized switching and provides service paths for

other subracks, also provides service processing interface, OMinterface, and system clock interface.

EPS 0-3 Performs the function of user plane processing and signaling

control.

TCS 0-4 Processes CS services and performs the functions of voice

adaptation and code conversion.

The TCS is configured in the TCR only in BM/TC separated mode.

2.2.3 Boards

The BSC6000 boards can be classified according to type: the OM board, the switching processing board, the clock processing board, the signaling processing board, the service

processing board, and the interface processing board, as described in Table 2-3.

2.3 Software ArchitectureThe BSC6000 software is designed with a layered architecture. Each layer is dedicated to its

own functions and provides services for other layers; however, each layer shields the technicalimplementation details and physical topology from the other layers. Figure 2-3 shows the

software architecture of the BSC6000.

resources and network resources, maintains mapping between service

control and resource instance, and controls the association between

various resources. Manages the resources and OM status, responds to the resource

request from the upper layer, and hides the resource implementation

from the upper layer.

Provides various service resources. (These resources are closely

related to the hardware. They encapsulate the TC/PCU and isolate theservice control of the upper layer from the hardware platform to

facilitate hardware development.)

2.4 ReliabilityThe resource pool design and redundancy mechanism are widely used in the system reliabilitydesign of the BSC6000. Techniques for detecting and isolating faults in the boards and in the

system are optimized and the software fault tolerance capability is improved to enhance

system reliability.

2.4.1 System Reliability

The BSC6000 system reliability is designed with the following features:

High reliability architecture designDual switching planes, with up to 120 Gbit/s GE star non-blocking switching capability per subrack, solves the bottleneck and single point failure in the deployment of the

high-capacity BSC6000.

Moreover, port trunking technology has been adopted on the switching boards. The porttrunking function allows data backup in case of link failure, thus preventing inter-plane

switchover and cascading switchover and improving the reliability of intra-systemcommunication.

Dual clock planes are used in clock transmission between the GCUa and the SCUa. Thus,a single point of failure does not affect the normal operation of the system clock.

Resource pool design


13/26




Page 13 of 26

In case of overload, the system implements load sharing between the control plane and

the user plane by employing the full resource pool design. This effectively avoidssuspension because of overload, thus improving resource usage and system reliability.

Redundancy mechanism

All the hardware in the BSC6000 has adopted the redundancy mechanism. The rapidswitchover between active and standby parts improves system reliability. Moreover, with

the quick fault detection and recovery feature, the impact of faults on the service isminimized.

Flow control

The system performs flow control based on the CPU and memory usage. Thus, theBSC6000 can continue working by regulating the items pertaining to performance

monitoring, resource auditing, and resource scheduling even in the case of CPU overloadand resource congestion. Therefore, system reliability has been enhanced.

2.4.2 Hardware Reliability

The BSC6000 hardware reliability is designed with the following features:

The system uses a multi-level cascaded and distributed cluster control mode. SeveralCPUs form a cluster processing system. Each module has distinct functions. The

communication channels between modules are based on the backup design oranti-suspension/breakdown design.

The system uses the redundancy design, as described in Table 2-5, to support hot

swapping of boards and backup of important modules. Therefore, the system has a strongerror tolerance capability.

Table 2-5 Board redundancy

A fault isolation mechanism is used. When entity A fails to accomplish a task, entity Bthat has the same functions as entity A takes over the task. Meanwhile, entity A is

isolated until it is restored.

When a board with a single function is faulty, restarting the board will generally solve

the problem.

Page 14 of 26

All boards support dual-BIOS. Faults at one BIOS do not affect the startup or operation

of the boards.

The system uses the non-volatile memory to store important data.

With advanced integrated circuits, the system features high integration, sophisticated

technology, and high reliability. All the parts of the system are of high quality and have to pass the aging test. The

process of hardware assembly is strictly quality-controlled which ensures the highstability and reliability for long-term operation.

2.4.3 Software Reliability

The BSC6000 software reliability is designed with the following features:

Scheduled check on crucial resources

The software check mechanism checks various software resources in the system. If aresource deadlock occurs because of software faults, the check mechanism can release

the locked resources and generate related logs and alarms. Task monitoring

When the software is running, internal software faults and some hardware faults can be

monitored through the monitoring process which keeps track of the task running statusand reports errors to the OM system.

Data check

The software performs regular or event-driven data consistency check, restores the data

selectively or by preference, and generates logs and alarms.

Data backup

Both the Back Administration Module and the host board support data backup to ensure

data reliability and consistency. Operation logs

The system automatically records the history operations in logs. The operation logs help

in locating and rectifying faults caused by improper operations.

3 Configurations3.1 Overview

Depending on whether or not the BSC6000 has a dedicated TCS for performing thetranscoding function, the BSC6000 supports two types of configuration modes: BM/TC

combined mode and BM/TC separated mode.

3.2 Hardware Configuration in BM/TC Combined ModeIn BM/TC combined mode, the BSC is not configured with the TCS. The boards thatimplement the TC functions are inserted into the slots of the MPS or EPS. With the same

capacity, fewer cabinets and fewer subracks are required in the BSC, thus increasing hardwareintegration.

3.3 Hardware Configuration in BM/TC Separated ModeWhen the BSC is located in a remote equipment room, it is configured in BM/TC separated

mode. The BSC is configured with a separate TCS, which is located in the TCR on the MSCside. Thus, transmission resources between the BSC and the MSC are saved because the voice

codec used on this interface is the efficient 16 kbit/s GSM codec.

Powerful Hardware Management Functions for Rapid Location and Rectification of

Hardware Faults

The BSC6000 provides a precaution mechanism for hardware fault, thus ensuring sufficient

time to rectify the fault before services are disrupted.

The BSC6000 also provides other functions, such as status query, data configuration, andstatus management of the internal physical devices.

When a hardware fault occurs, the BSC6000 alerts the user by generating alarms and flashing

indicators, and provides suggestions to guide the user in troubleshooting. The alarm is clearedupon rectification of the fault.

The BSC6000 provides functions for isolating the faulty part, such as activating ordeactivating the faulty part. When a faulty part needs to be replaced, the hot swapping

function enables the substitute to be rapidly powered on, thus reducing the time required forfault rectification.

In case of emergency, you can reset the board to quickly rectify the fault.

Advanced Software Management Functions for Secure and Smooth Upgrade

The BSC6000 provides the remote upgrade tool, which enables the operator to upgrade the

software at the operation and maintenance center without affecting ongoing services. Theremote upgrade tool backs up crucial data in the system. If the upgrade fails, a version

rollback is performed immediately and the system returns to normal in a short period.

After the upgrade is complete, a version consistency check is performed to ensure that theversion is correct.

Rich Tracing and Detection Mechanisms for Reliably Monitoring Network Status

The BSC6000 provides tracing and detection functions of multiple layers and multiple levels

to accurately locate faults. These functions include user tracing, interface tracing, messagetracing, fault detection on the physical layer, fault detection on the data link layer, and

detection of other faults.

Tracing messages are saved as files, which can be viewed through the review tracing function

of the LMT.

Easy Equipment Installation, Commissioning, and Efficient Network Upgrade Scheme

for Rapid Network Establishment

Before delivery, Huawei BSC6000 is installed with boards, operating system, and common

data. In addition, it is correctly assembled and passes the rigorous test. Only the cabinet and

cables need to be installed at the site. After hardware installation is complete, the software anddata files can be loaded to commission the software and hardware.
