2 Introduction to Reconfiguration

About This Chapter

This chapter defines reconfiguration and describes the reconfiguration tools.

2.1 DefinitionReconfiguration refers to a process of adding, deleting, or modifying the data of the RAN system(consisting of at least one BSC6900 and one base station) after it starts operating.

2.2 ToolsThe Local Maintenance Terminal (LMT) and the Configuration Management Express (CME)can be used to configure the BSC6900.

RANReconfiguration Guide 2 Introduction to Reconfiguration

2.1 DefinitionReconfiguration refers to a process of adding, deleting, or modifying the data of the RAN system(consisting of at least one BSC6900 and one base station) after it starts operating.

The RAN is reconfigured in the following scenarios:

l Network optimizationNetwork optimization is a process of adjusting and optimizing the network performancebased on the data that is obtained from performance measurements or drive tests when thenetwork is in service.

l System capacity expansionSystem capacity expansion enables the BSC system to serve more users through hardwareaddition or configuration modification in the existing network.

This document focuses on the data to be prepared and reconfiguration procedures. However, itdoes not focus on the data analysis process of network optimization and the number of boardsand links for capacity expansion that are subject to actual network conditions.

2.2 ToolsThe Local Maintenance Terminal (LMT) and the Configuration Management Express (CME)can be used to configure the BSC6900.

Table 2-1 describes the tools used in reconfiguration. This document describes only the datareconfiguration through MML commands on the LMT.

Table 2-1 Reconfiguration tools

Data Configuration Tool Function

LMT Online or offline configuration of the BSC6900 can beperformed through MML commands.

CME BSC6900 configuration can be performed through the CMEgraphic user interface.l In integrated mode, the configuration data can be sent to

the BSC6900 through the M2000 immediately or at aspecified time. This mode is used for data reconfiguration.

l In standalone mode, the configuration file needs to beexported after the configuration and then loaded to theBSC6900 through the LMT or M2000 for the data to takeeffect. This mode applies to BSC6900 initialconfiguration.

5.1 Changing Signaling PointsWhen the BSC6900 is relocated or network optimization is performed, the originating signalingpoint code (OPC) and destination signaling point code (DPC) are changed. In this case, you needto change the related settings.

Prerequisitesl The LMT runs normally.l The LMT communicates with the BSC6900 properly.

Context

CAUTIONChanging signaling points will interrupt BSC6900 services. Therefore, change signaling pointsat midnight when the traffic load is light.

l When the OPC is used by an M3UA local entity (M3LE), set all subracks to ineffectivemode and the change the OPC.

l If the OPC to be changed is not used by an M3LE, change the OPC in online mode.

Procedurel Change an OPC.

1. Run the LST M3LE command to query whether the OPC is used by M3LE.– If the OPC to be changed is used by an M3LE, change the OPC as follows:

a. Run the SET CFGDATAINEFFECTIVE command to set all subracks toineffective mode.

b. Run the MOD OPC command to change OSP name and OSP code.c. Run the SET CFGDATAEFFECTIVE command to set all subracks to

effective mode.d. Run the FMT DATA command to create a data configuration file.e. Run the RST BSC command to reset the BSC6900.

– If the OPC to be changed is not used by an M3LE, change the OPC as follows:

a. Run the MOD OPC command to change OSP name and OSP code.l Change a DPC.

1. Run the MOD N7DPC command to change OSP name and OSP code.

----End

5.2 Changing the Work Mode of a BoardThe work mode of a BSC6900 board can be changed to improve the board reliability.

Prerequisitesl The board works in independent mode.

l The board supports active/standby mode.

l No board of the same type as the board is configured in the standby slot.

Context

CAUTIONDPU boards are in resource pool backup mode. Therefore, the following operations cannot beperformed on them.

After the work mode of a board is changed, reset the BSC6900.

After the work mode of a board is changed, reset the Verifying Network Reliability.

A BSC6900 board works either in independent or active/standby mode. The board can bechanged from independent mode to active/standby mode to improve its reliability.

After a board is changed from independent mode to active/standby mode, the BSC6900automatically sends the configuration data to the active and standby boards. For IP-based activeand standby interface boards, you must configure the IP addresses of the ports on the standbyIP interface board or the active/standby port relation between the active IP interface board andthe standby IP interface board.



19

If ports on the active IP interface board and those on the standby IP interfaces are not in active/standby mode, run the ADD ETHIP command to configure the IP addresses of the ports on thestandby IP interface board.

If ports on the active IP interface board and those on the standby IP interfaces are in active/standby mode, the IP addresses of the ports on the standby IP interface board are the same asthose of the ports on the active IP interface board. Run the ADD ETHREDPORT command toconfigure the active/standby port relation between the active IP interface board and the standbyIP interface board.

This operation is applicable to all the boards except the OMU board. For instructions on how tochange an OMU board from independent mode to active/standby mode, see Switchover BetweenActive and Standby OMUs.

5.5 Adding Boards and SubracksAs traffic volume increases, the BSC6900 cannot meet the increasing service requirements. Inthis case, you can add boards or subracks to expand system capacity.



27

5.5.1 Adding a SubrackThis section describes procedures and precautions for adding subracks.

Prerequisitesl Network design is complete.

Network design involves planning of traffic volume in each subrack, planning of thequantity of subracks, and planning of the quantity and types of boards and slots for theboards.Contact Huawei to obtain the detailed network design and planning scheme.

l Tools required for adding subracks are available. The tools are the ESD wrist strap, socketwrench, Phillips screwdriver, flat-head screwdriver, ESD box or bag, dustfree cotton cloth,and fiber cleaner.

l The parts needed for adding subracks are all available. The parts include subracks andscrews.

l If there is space in the cabinet, add the subrack there. If there is no space for a new subrack,add a cabinet.

Context

CAUTIONl To avoid damage to the boards, ASIC chips, or other electronic components, wear an ESD

wrist strap properly. Ensure that the ESD wrist strap is properly connected to the ESDconnector on the cabinet. If no ESD wrist strap or no proper grounding point is available,wear ESD gloves.

l It is recommended that you need to use the same board type to replace the old board. To usea board of the different version to replace the board (for example, use a board of version bto replace a board of version a), contact Huawei for technical support.

Procedure

Step 1 Turn off the power switch for the new subrack according to instructions in Distribution of PowerSwitches.

Step 2 Optional: (This step is only implemented when floating nuts are not installed in the mountingbar at the front side of the cabinet.) Take floating nuts out of the ESD bag at the bottom of thecabinet and install them in the place highlighted in yellow, as shown in Figure 5-3.



28

Figure 5-3 Installing Floating Nuts

NOTE

Three holes in the mounting bar are known as 1 U space. One subrack occupies 36 holes.

One subrack is fixed by 4 pairs of floating nuts installed symmetrically. The floating nuts are installed in the3rd, 12th, 25th, and 34th holes above the guide rail where the subrack will be installed.

Step 3 Two people hold the mounting ears and support the base of the subrack. Slide the subrack alongthe guiding rail into the cabinet, and then fasten the screws to fix the subrack.

Step 4 Set the DIP switch based on the new subrack location according to instructions in DIP Switchon the Subrack.

CAUTIONl You must set the DIP switch before powering on the subrack. The setting after the power-

on is invalid.l Different subracks must have different DIP-switch settings. If two subracks in the

BSC6900 share the same DIP-switch settings, services on the two subracks will beinterrupted.

l If the DIP-switch setting of the new subrack is the same as that of another subrack and servicesin the two subracks are consequently interrupted, set the DIP switches of the two subracksproperly and reset the two subracks to restore services.

Step 5 Install the power cables for the new subrack.

Before the BSC6900 delivery, its subrack power cables have been bound in the cabinet. Youonly need to connect the power cables to the power ports.

1. Peel off the insulation layer of the power cable connector, as shown in Figure 5-4.



29

Step 7 Install the inter-SCUa or inter-SCUb cables:



31

l If the new subrack is to be configured with SCUa boards, install the inter-SCUa cablesbetween different subracks according to instructions in Install the Inter-SCUa CablesBetween Different Subracks.

l If the new subrack is to be configured with SCUb boards, install inter-SCUb SFP+ high-speed cables between different subracks according to instructions in Installing the Inter-SCUb SFP+ High-Speed Cables Between Different Subracks.

Step 8 Install the Ethernet cables or optical fiber for connecting the interface boards.

Step 9 Attach the engineering labels to the signal cables according to instructions in Attaching theEngineering Labels to the Signal Cables.

Step 10 Check whether cables in the new subrack are connected correctly.

Step 11 Log in to the LMT and add the new subrack and boards as follows:

1. Run the ADD SUBRACK command to add a subrack.For example: ADD SUBRACK: SRN=1, SRName="1";

2. Run the SET SCUPORT command to enable the ports on SCUa boards in the new subrack.If the new subrack is configured with SCUa boards
