The invention relates to a radio communication system, a base station control equipment and a mobile station equipment which constitute the radio communication system. An object of the present invention to maintain high channel capacity while adapting to geographical distribution of a mobile station which can perform soft hand-off. The base station control equipment comprises a transmission-quality measuring section for measuring the transmission qualities of reception waves arriving from mobile stations. In the process of channel control, the base station control equipment is given the allowable maximum number N of radio channels through which a BTS transmits in parallel, as a tolerable limit of interference with wireless zones formed by a local station and/or other stations. It allots, in descending order of the transmission qualities, N or less radio channels to the mobile stations which are transmitting ends of reception waves having measured transmission qualities.
