Abstract

PURPOSE:To increase the efficiency of communication, by the centralized control of a central station for the selection of control channel and switching at failure used among a plurality of base stations and a number of mobile stations within a radio communication area. CONSTITUTION:The base station which makes communication and control with a number of mobile stations 6 with in a communication area is provided with a communication transceiver 2, control channel transceiver 3, and interference detecting receiver 4, and connection with the mobile station 6 is made with radio and the connection to the central station 5 is made via lines 10-14. When an interference detecting receiver 4 at normal operation detects the interference more than the threshold value at the existing control channel, it is informed to the central station and the central station designates other channels to change the channel for a control channel transceiver 3 and the interference detecting receiver 4. Each mobile station starts the scanning for predetermined channel through the increase in the S/N of the control channel in use and fixes it to the channels more than the threshold value. Thus, the communication efficiency for a number of mobile stations can be kept and increased.
