1.2 2725告警描述
ADJ_CELL_ID_ERROR_A（Description）
The 2725 (ADJ_CELL_ID_ERROR_A) alarm indicates that the source cell's adjacent cell information in the BSS Radio Network Configuration Database is incorrect. The source BSC is able to notice this before it sends a HANDOVER_COMMAND to the MS. The MSC sends layer 2 information in the HANDOVER_COMMAND message to the BSC. Layer 3 information contains the BCCH frequency and the BSIC of the target cell.
The source BSC compares the BCCH frequency and BSIC with the original information it has on the handover candidates. If these do not match, there has been a failure in candidate cell identification.
The alarm gives information on the source cell whose adjacent cell definitions are incorrect.
