Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a radio channel is assigned to a mobile station without the appropriate radio channel is assigned to a mobile station without the need for any complicated control of the mobile station and a base station. SOLUTION: This radio channel assignment method assigns a 'radio channel to an optional mobile station 5 that is resident in a simultaneous call area 4 by pluralities of base stations 2a, 2b, 2c that configure the one simultaneous call area 4. In this method, each of the base stations 2a, 2b, 2c assigns at least one of communication slots to a control channel, the mobile station 5 acquires each control channel of the base stations, and in the case that the mobile station 5 sends an assignment request message of a communication channel to one of the base stations 2a, 2b, 2c, the base station 2a being one of the base stations 2a, 2b, 2c sends a channel assignment reject message to the mobile station 5 when no available communication slot is in existence.  In the case that the mobile station 5 receives the reject message, the mobile station 5 sends the assignment request message of a communication channel to the other base station 2c based on a timing obtained by the acquisition of the control channel.
