In a cellular mobile communication system, a cellular mobile communications system comprising a first plurality of base stations sharing a pair of first uplink and first downlink common frequencies (f j , F j ), and a mobile station for transmitting to the base stations an uplink signal on the first uplink common frequency (f j ). Each of the first plurality of base stations transmits to the mobile station a downlink signal on the first downlink common frequency (F j ). The mobile station includes means for switching the uplink signal from the first uplink common frequency (f j ) to a second uplink common frequency (f k ) of a second plurality of base stations depending on the field strength of the downlink signal. Each of the first plurality of base stations includes means for receiving from the mobile station an uplink signal transmitted on the first uplink common frequency (f j ), and means for receiving from the mobile station an uplink signal transmitted on a second uplink common frequency (f k ) of the second plurality of base stations.
