M3701:CELL_CALL_DROPS_CONN_FAIL_BSC_LOOP
After seizing a channel, an MS is in the BSC local switch state. The BTS sends the BSC a CONN FAIL IND message due to the faulty radio links or the faulty hardware, indicating that call drops occur on the Um interface because of the failure in connecting the radio links. This measurement provides the number of call drops when the cause value carried in the CONN FAIL IND message is radio link failure (0x01), handover access failure (0x02), om intervention (0x07), or radio resource not available (0x21).
Integer number or integer.
If the BSC receives a CONN FAIL IND message, the BSC regards it as a call drop. The release procedure is started. If the MS is detected in the BSC local switch state, this counter is measured.
This is an original counter without involving any formula.
