Abstract:
A method for automatically recovering a call in a mobile station for a CDMA (Code Division Multiple Access) mobile communication system, the method comprising the steps of:(a) upon detection of an unintended dropped call, performing energy measurement on pilot signals of neighbor base stations and determining a base station according to the energy measurement, said pilot signals being received from a previous service base station; (b) slewing, when the determined base station is not identical to the previous service base station, a PN offset timing position of the mobile station to a PN offset timing position corresponding to the determined base station; (c) obtaining the system information of the determined base station by demodulating a sync channel message and a paging channel message from the determined base station; and (d) performing automatic redialing on the dropped call.
