Using the CME to Perform Batch Configuration for Newly Deployed eNodeBs

6.4.4 Hardware Adjustment

BBP installation varies with the BBU type as follows:

l Inter-BBP CA requires an LBBPd or UBBP to be installed in slot 2 or 3 of a BBU3900, if configured, for capacity expansion or upgrades.

l This requirement does not apply to a BBU3910.

When an eNodeB is restarted, all served cells are reactivated and may be randomly distributed on BBPs. It is possible that inter-frequency cells for CA are all re-established on LBBPc boards. In this case, CA does not work between these cells. To prevent this, you are advised to set a fixed mapping between cells and slots. The procedure is as follows:

1. Run the LST EUCELLSECTOREQM command on a macro eNodeB or the LST EUSECTOREQMGROUP command on a LampSite eNodeB to check the existing mapping configuration. If the baseband equipment ID is in the range of 0 to 23 in the command output, the specified cell has been mapped to the specified baseband equipment. If the ID is 255, the cell has not been mapped to any baseband equipment, and then go to the next step.

2. Run the ADD BASEBANDEQM command to add baseband equipment. Ensure that the baseband equipment ID does not collide with any existing baseband equipment ID. 3. Run the MOD EUCELLSECTOREQM command on the macro eNodeB or the MOD

EUSECTOREQMGROUP command on the LampSite eNodeB to map the cell to the new baseband equipment. After that, the cell will be re-established. Then, the mapping takes effect.

6.4.5.1 Using the CME to Perform Batch Configuration for Newly Deployed

eNodeBs

Enter the values of the parameters listed in Table 6-3 or Table 6-4 in a summary data file, which also contains other data for the new eNodeBs to be deployed. Then, import the summary data file into the Configuration Management Express (CME) for batch configuration.

For detailed instructions, see section "Creating eNodeBs in Batches" in the initial

configuration guide for the eNodeB, which is available in the eNodeB product documentation. The summary data file may be a scenario-specific file provided by the CME or a customized file, depending on the following conditions:

l The managed objects (MOs) in Table 6-3 or Table 6-4 are contained in a scenario- specific summary data file. In this situation, set the parameters in the MOs, and then verify and save the file.

l Some MOs in Table 6-3 or Table 6-4 are not contained in a scenario-specific summary data file. In this situation, customize a summary data file to include the MOs before you can set the parameters.
