Abstract
A portable communication device has a software processing section and a hardware processing section which are capable of performing wireless voice communication and wireless data communication of different communication modes and communication channels, wherein the portable communication device automatically matches the communication device of the portable communication device and the communication device of the opposite party before the communication is started. The transmitting side of the communication requests switching of the present communication mode or communication channel of the opposite side through a data signal so that the two sides use the same communication mode or communication channel. The transmitting side, thereafter, switches to the wireless voice communication and calls out. The receiving side of the communication switches to the wireless voice communication in accordance with the switching request signal transmitted from the transmitting side, thereby enabling voice communication.
