CS call drop may be caused by abnormal release caused by the lost synchronization of links because of poor network coverage (including adjacent cell missing, small handover area. As a result, UE closes the transmitter abnormally or uplink demodulation is asynchronous. To solve the problem, network coverage must be improved. In the early network, call drops are mainly caused by this reason.
CS call drops may be caused by link releasing due to downlink SRB reset. This reason is mainly caused by poor network coverage (including adjacent cell missing and small handover area). To solve the problem, the network coverage must be improved. In the early network, call drops are mainly caused by this reason.
If IU CS interface (AAL2 path) is abnormal, RNC initializes the release. In practice, this reason seldom occurs. If this reason occurs, the problem may be caused by any faulty or defective equipment. In some versions of RNC, normal release is recorded as abnormal release during the RB setup process. CS call drops may be caused by other reasons. There are few call drop statistics in RNC (Version 12). Such reasons as process interaction timeout and cell update failure are recorded in CS_RAB_DROP_OTHER. In practice, many call drops are caused by process interaction timeout and cell update failure. Therefore, these call drops are recorded in CS_RAB_DROP_OTHER.
