ABSTRACT:
In order to perform communication frame switching without cutting off data communication, a terminal which has received a real-time data communication connection request during communication using a data communication frame notifies the other party with which communication is being made of a communication frame change and information of the change timing via a control channel, and also notifies the terminal originating the real-time data communication connection request of the state of the frame being used via the control channel, and changes the communication frame. Further, following changing of the frame, the terminal notifies the terminal originating the real-time data communication connection request of confirmation of connection, and starts real-time data communication via real-time channels. Thus, frame switching can be performed without cutting off data communication.
