WIRELESS COMMUNICATION SYSTEM, AIR INTERFACE SYNCHRONIZING METHOD, BASE STATION AND ITS CONTROLLING APPARATUS

摘要

A radio communication system, an air interface synchronization method, a BS, and a BSC are disclosed herein. The radio communication system includes at least two BSs and a BSC. The two BSs are adapted to: receive the same signal sent by an MS, record time of receiving the signal, and report the time to a BSC; and the BSC is adapted to obtain the signal receiving time recorded by the two BSs, obtain an air interface offset between the two BSs according to the signal receiving time, and deliver the offset to the two BSs. The two BSs are further adapted to synchronize air interfaces of the two BSs according to the offset. The embodiments of the present invention use the existing radio network resources to synchronize the air interfaces of the BSs conveniently and cost-effectively.
