Abstract: In a mobile communication system comprising a control station, a plurality of base stations each for defining a service area, and a plurality of mobile stations, in a standby mode, each of the mobile stations monitors reception levels and interference levels of traffic channels from the base stations and transmits first priority lists of traffic channels via the base stations to the control station. Also, the control station renews and stores second priority lists of traffic channels for the base stations in accordance with first priority lists of traffic channels from the base stations and further transmits these second priority lists to the base stations upon receipt of a request for call connection. In a call connection mode, each of the base stations allocate optimum traffic channels to the mobile stations under the control of each of the base stations in accordance with one of the second priority lists of traffic channels.
