<P>PROBLEM TO BE SOLVED: To perform prompt acquisition/tracking control of a reception synchronization timing at the time of shifting a processing of a fault base band processing part to an unused base band processing part. <P>SOLUTION: In a synchronization acquisition/synchronization tracking data preservation part 59, synchronization acquisition/synchronization tracking data for reception data of an allocated mobile terminal for each base band processing part 54 are successively preserved. The respective base band processing parts are monitored by an alarm monitoring part 57, and at the time of detecting fault generation in one of the base band processing parts, a base band processing part switching part 53 is controlled and replacement with the base band processing part 55 to be used at the time of the fault generation is performed. The synchronization acquisition/synchronization tracking data before the fault generation preserved in the synchronization acquisition/ synchronization tracking data preservation part are transferred to the base band processing part to be used at the time of the fault generation and a data processing of the mobile terminal allocated to the fault generation base band processing part is continued while keeping an optimum reception synchronization timing in the base band processing part to be used at the time of the fault generation. <P>COPYRIGHT: (C)2003,JPO |
