2 Introduction to Reconfiguration

2.1 Definition Reconfiguration 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 optimization Network optimization is a process of adjusting and optimizing the network performance based on the data that is obtained from performance measurements or drive tests when the network is in service.

l

System capacity expansion System capacity expansion enables the BSC system to serve more users through hardware addition or configuration modification in the existing network.

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

2.2 Tools The 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 data reconfiguration through MML commands on the LMT. Table 2-1 Reconfiguration tools Data Configuration Tool

Function

LMT

Online or offline configuration of the BSC6900 can be performed through MML commands.

CME

BSC6900 configuration can be performed through the CME graphic user interface. l In integrated mode, the configuration data can be sent to the BSC6900 through the M2000 immediately or at a specified time. This mode is used for data reconfiguration. l In standalone mode, the configuration file needs to be exported after the configuration and then loaded to the BSC6900 through the LMT or M2000 for the data to take effect. This mode applies to BSC6900 initial configuration.

5.5 Adding Boards and Subracks As traffic volume increases, the BSC6900 cannot meet the increasing service requirements. In this case, you can add boards or subracks to expand system capacity. Issue 04 (2012-09-17)


27



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

Prerequisites l

Network design is complete. Network design involves planning of traffic volume in each subrack, planning of the quantity of subracks, and planning of the quantity and types of boards and slots for the boards. 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, socket wrench, 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 and screws.

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

CAUTION l 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 ESD connector 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 use a board of the different version to replace the board (for example, use a board of version b to 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 Power Switches. Step 2 Optional: (This step is only implemented when floating nuts are not installed in the mounting bar at the front side of the cabinet.) Take floating nuts out of the ESD bag at the bottom of the cabinet and install them in the place highlighted in yellow, as shown in Figure 5-3.

Issue 04 (2012-09-17)


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 the 3rd, 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 along the 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 Switch on the Subrack.

CAUTION l You must set the DIP switch before powering on the subrack. The setting after the poweron 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 be interrupted. l If the DIP-switch setting of the new subrack is the same as that of another subrack and services in the two subracks are consequently interrupted, set the DIP switches of the two subracks properly 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. You only need to connect the power cables to the power ports. 1.

l

If the WBBPd board is installed in slot 2 or 3, the board can provide six CPRI ports, which facilitates onsite configurations.

l

If a WBBPa or WBBPb board has been installed in slot 2 or 3 and the interference cancellation function is to be enabled for it, it must be removed first. Moreover, at least a WBBPd board must be configured in slot 2 or 3. For details on how to replace a board, see the BBU3900 Hardware Maintenance Guide.

l

If more CPRI ports are required by a NodeB, the WBBP board can be installed in slot 3 preferentially. If slot 3 is occupied, install the board in slot 2.

l

If the NodeB does not need more CPRI ports, the WBBP board can be installed in one of the following slots: slot 3, slot 0, slot 1, slot 2, slot 4, and slot 5, which are arranged in descending order of priority. This ensures that a UMTS baseband board, and at least a WBBPd board, is installed in slot 2 or 3 when the fifth baseband board is to be installed for capacity expansion purposes.

Context

Procedure Step 1 Run the NodeB MML command ADD BRD to add a baseband board for a NodeB. Step 2 After a baseband board is added, add this board to the corresponding uplink and downlink baseband recourse groups.

7.1 Reconfiguring a Cell This section describes how to reconfigure a cell, including cell parameters.

7.1.1 Modifying the Power of a Cell This section describes how to modify the maximum transmit power of a cell or the power of different channels in the cell when the network is optimized.

Prerequisites l

The BSC6900 and the NodeB work properly.

l

The current user has the BSC6900 control rights concerning data configuration management. The control rights of data configuration management can be queried through LST CMCTRL.

l

The BSC6900 is online. The current data configuration mode of the BSC6900 can be queried through the LST CFGMODE.

Context You can modify the following power parameters: l

Maximum transmit power of the cell

l

PCPICH power

l

Max./Min. TX power of the PCPICH

l

PSCH power

l

SSCH power

l

AICH power

l

PICH power

l

BCH power

l

PCH power

l

Max. TX power of the FACH

CAUTION l If the Max. TX power of the cell at the BSC6900 is greater than that at the NodeB, the logical cell cannot be set up or the cell reconfiguration process fails. l If the Max. TX power of the cell at the BSC6900 is too small, the cell reconfiguration process fails. l The Max. TX power of the BSC6900 and NodeB must be the same.

Issue 04 (2012-09-17)


64


7 Reconfiguring the UMTS Network NOTE

l

Among these parameters, the Physical Common Pilot Channel (PCPICH) power, Max./Min. TX power of the PCPICH, and Max. TX power of the cell are absolute values. The rest of the parameters are power offsets from the PCPICH power.

l

If the Secondary-Common Control Physical Channel (SCCPCH) or Physical Random Access Channel (PRACH) is in service, modifying the Max. TX power of the FACH or the PCH/PICH/ AICH power can trigger the COMMON TRANSPORT CHANNEL RECONFIGURATION process on the Iub interface.

l

If the cell is in service, modifying the Max. TX power of the cell or the PCPICH/PSCH /SSCH/BCH power can trigger the CELL RECONFIGURATION process on the Iub interface.

l

When the cell is in service, change the maximum TX power of the cell or the PCPICH/PSCH/SSCH/ BCH power. l If the maximum TX power of the cell is changed to a value within the range specified by the maximum and minimum TX power for NodeB cells, the change will take effect and trigger the CELL RECONFIGURATION process on the Iub interface. l If the maximum TX power of the cell is changed to a value greater than the maximum TX power or less than the minimum TX power for NodeB cells, the change will neither take effect nor trigger the CELL RECONFIGURATION process on the Iub interface. When this occurs, the BSC6900 will automatically report ALM-22215 UMTS Cell Max DL Power Mismatch.

Context NOTE

Assume that the RNC has cell A and cell B, and the two cells are neighboring cells. Removing a unidirectional neighbor relation means, for example, cell B is removed as a neighboring cell from cell A, but cell A is not removed from cell B. Removing a bidirectional neighbor relation means that cell B is removed from cell A, and likewise, cell A is removed from cell B.

Procedure l

l

l

Remove a unidirectional intra-frequency neighbor relation of a cell. 1.

Run the LST UINTRAFREQNCELL command to view intra-frequency neighboring cells.

2.

Run the RMV UINTRAFREQNCELL command to remove an intra-frequency neighboring cell.

3.

Run the LST UINTRAFREQNCELL command to check whether the neighboring cell is correctly removed.

Remove a unidirectional inter-frequency neighbor relation of a cell. 1.

Run the LST UINTERFREQNCELL command to view inter-frequency neighboring cells of the specified cell.

2.

Run the RMV UINTERFREQNCELL command to remove an inter-frequency neighboring cell.

3.

Run the LST UINTERFREQNCELL command to check whether the neighboring cell is removed.

Remove a unidirectional inter-RAT neighbor relation of a cell. 1.

Run the LST U2GNCELL command to view the neighboring GSM cells of the specified cell.

2.

Run the RMV U2GNCELL command to remove a neighboring GSM cell.

3.

Run the LST U2GNCELL command to check whether the neighboring cell is removed.

Remove a bidirectional neighbor relation between the current cell and another cell. 1.

If the current cell is in service, run the HO UCELL command to force the handover of UEs from the current cell to another cell.

2.

If the current cell is in an active state, run the DEA UCELL command to deactivate the cell.

3.

Run the RMV UNRELATION command and specify one or several types of neighboring cells in Neighboring Cell Type, and then remove the bidirectional neighbor relations between the current cell and the specified neighboring cells within the RNC. NOTE

l The RMV UNRELATION command can remove only the bidirectional neighboring cells that are controlled by the local BSC6900. l To remove the bidirectional neighboring cells that are controlled by another BSC6900, you need to perform the operation on the other BSC6900.

4.

Run the ACT UCELL command to make the cell enter the service state again.

5.

Run the DSP UCELL command to check whether the status of the cell is correct.
