PURPOSE:To complete simplex communication normally even when a carrier for a wave other than the one being outputted exists in a mobile station individual communication by using a control channel. CONSTITUTION:When communication is completed by an outgoing mobile station 1 which performs the individual communication by simplex operation, the outgoing mobile station 1 sends out a cutoff request signal 28 via an up control channel. A base station controller 5 receiving the cutoff request signal 28 sends out cutoff information 29 to an exchange 6. The exchange 6 receiving the cutoff information 29 sends out speech channel release information 30 to the base station controller 5, and the base station controller 5 receiving the speech channel release information 30 sends out a clearing signal 31 to the outgoing mobile station 1 and an incoming mobile station 2 via a down speech channel, then, the communication is completed. |
