ZTM330:BSCRPT_TOTAL_CELL_CALL_DROPS_REL_IND_TCH
Description
When the BTS receives a DISC frame sent from the MS in the multiframe link setup state, the BTS sends a REL IND message to the BSC. Through the REL IND message, the BSC is notified that call drop occurs on the air interface. This measurement provides the number of call drops on the TCHs per BSC (release indication) when the call drops are caused by release indication.
