PROBLEM TO BE SOLVED: To attain improvement in the communication quality of a mobile station in a simple configuration by performing time management by providing a base station with a recording means, and surely avoiding overreach to cause the reduction of communication quality by limiting relay centers to be operated one by one through one time of operation even in radio communication system having plural relay centers. SOLUTION: When a transmission SW is inputted, at the base station, a control part 1 activates the first relay center through a transmission part 3 and starts measuring the time of a timer and while recording an audio signal from a microphone through a recording part 2, it is transmitted by the transmission part 3. The mobile station receives the transmission of the base station from the first relay center and when the base station inputs an end SW, the control part 1 stops measuring the time of the timer and the transmission of the transmission part 3. Next, the base station activates the second relay center through the transmission part 3 and broadcasting contents recorded by the recording part 2 are automatically transmitted to the transmission part 3 by the timer. Thus, the generation of beat sounds or noises caused by simultaneously transmitting the first and second relay centers at the same frequency is avoided and satisfactory sounds and data can be transmitted. |
