PROBLEM TO BE SOLVED: To provide a synchronization influencing system in a mobile communication body base station group which enables wireless synchronous periodic monitoring to be completed in a short time, base station group, and synchronization influencing method. SOLUTION: There are provided in somewhere of a group of base stations 1-7 for relaying communication of a mobile communication body according to a time division multiple access (TDMA) method, a GPS mounted base station that may be a synchronization influencing station 1 which generates a timing signal with accuracy required for the time division multiple access (TDMA) method and also synchronizes timing signals of the other stations; a plurality of GPS non-mounted base stations 2-7 each of which may be a relay station 5 for receiving a synchronization promoting signal transmitted from the synchronization influencing station 1 and promotes timing signal matching with the other stations, and relays the signal to the other stations in a chain manner; a radio control unit 11 which makes a response using a response signal from the GPS non-mounted base stations 2-7 to the synchronization influencing station 1; and a communication control unit 12 which measures strengths of response signals from the GPS non-mounted base stations 2-7 and designates a weakest response station 5 that made a response at a minimum practical use level, as a relay station.
