摘要

To provide a radio communication system that can achieve both acceleration of data communication and voice communication.SOLUTION: When communicating in a fast data mode to transmit a voice frame in inserting data for data communication instead of a digital voice signal into the voice frame, a transmission unit follows an instruction from a controller, inserts the data for data communication into the voice frame and a data frame, generates a packet into which information indicating that the data for data communication is inserted into the voice frame is inserted, and converts the packet into a radio signal to transmit it. On the other hand, when a PTT switch is depressed during communication in the fast data mode, a controller instructs the transmission unit to switch the communication mode to a slow data mode to transmit the voice frame in inserting the digital voice signal into it.SELECTED DRAWING: Figure 1
