<p>PROBLEM TO BE SOLVED: To provide an air synchronous method and base station synchronization system, capable of maintaining the accuracy of a frame clock by air synchronization and preventing generation of a communication fault even when some hindrance occurs in a communication with a GPS satellite.SOLUTION: The air synchronous method is typically configured so that a synchronization base station (a base station 110a) receives a control signal transmitted by a synchronization source base station (a base station 110b) before air synchronization. The synchronization source base station transmits a control signal and the synchronization base station receives the control signal. The synchronization source base station transmits a transmission time difference between a transmitted control signal and a subsequently transmitted control signal in a wireless or wire manner. The synchronization base station corrects reception timing when the control signal is received from the synchronization source base station, using the received transmission time difference.</p> |
