PURPOSE:To attain the mobile communication with high utilizing efficiency of radio wave by controlling a carrier frequency of a base station in response to the number of talking channels used by the base station and the operating state of the talking channel of adjacent base stations. CONSTITUTION:A controller 6 provided newly to control this system controls the carrier frequency of an own base station in response to the operating state of the talking channel of adjacent base stations 1 and the number of talking channels used by the own base station 1. Since a base station 1B has no mobile station 2 to be communicated with, no modulation is necessary and the mobile station 2 does not always make communication. Then, the traffic treated by each base station is changed timewise and it is normal that the load is not uniform. In this case, each base station 1 communicates with each other and any base station 1 used the talking channel having a high base band frequency, then adjacent base stations 1 are controlled so as to withhold the use of the talking channel having the high frequency, the mutual interference is reduced and excellent communication is attained. |
