Power measuring reference signals from a plurality of base stations are transmitted with a predetermined electric power. These reference signals transmitted from the base stations are received by a mobile station. The propagation loss of each base station is detected in response to a reception power of the received reference signal. When the mobile station issues a communication request, the mobile station connects to a communication network between it and a base station with the detected smallest propagation loss. Then, a ratio between the reception power of the reference signal transmitted from the base station connected with the communication network and reception powers of the reference signals transmitted from all other base stations using the same frequency band as that of the base station connected with the communication network is detected and the value of the detected ratio is transmitted to the base station. Then, the base station controls the transmission power of the communication network based on the value of this ratio.
