Abstract
A method and system for monitoring the traffic carrier performance of a CDMA carrier in a mobile communication system are provided. The method and system assign a preferred traffic carrier to each mobile station. During a drive-test, the preferred traffic carrier is assigned to the respective mobile station either originating or receiving a call. In the event of a dropped call, the system attempts to re-establish the call on the preferred traffic carrier to provide continuous monitoring on the same traffic carrier when the call is retried. If the preferred traffic carrier is not available when the BSC or base station assigns a traffic carrier, an alternate traffic carrier can be assigned at the call setup. After the call setup procedure is completed, a handoff procedure is initiated to transfer the call from the alternate traffic carrier to the preferred traffic carrier after a predetermined time if the preferred traffic carrier is available.
