When the user operates (push) the dial keys 204a and 204b on the operation side mobile phone 2, a key operation signal corresponding to the operated key (hereinafter referred to as an operation key) is input from the key input unit 204 to the control unit 203. Is done. As shown in FIG. 5 (a), after the key operation signal corresponding to the telephone number of the mobile device side mobile phone 3 is input to the control unit 203, the key operation signal corresponding to the line connection key 204b is input. (Step S 1) (Here, the telephone number signal and the line connection signal output from the key input unit 204 constitute a line connection request signal), and the communication unit 206 transmits the base station LS I of the area, the public Mobile device side via network N A signal requesting a call is transmitted to the base station LS2 on the mobile phone 3 side (step S2). The base station LS2 that has received the call request establishes a radio channel link with the communication unit 306 (see FIG. 4 (a)) of the mobile phone 3 on the mobile device side, and transmits a signal to notify the incoming call to the communication unit 300. .

As shown in FIG. 5 (b), when an incoming call notification is input to the communication unit 306 of the mobile phone 3 on the mobile device side (step S5), the automatic incoming call means (not shown) of the control unit 303 permits the connection. A signal to be transmitted is transmitted from the communication unit 306 to the communication unit 206 of the operating-side mobile phone 2 via the base station LS2, the public network N, and the base station LSI (step S6). As a result, the control unit 303 determines that the line is connected (step S7), and enters a state in which an audio signal can be received from the operation-side mobile phone 2.

Also, as shown in FIG. 5 (a), when the operation-side mobile phone 2 receives a signal permitting connection (step S3), the control unit 203 determines that the line is connected (step S4), Mobile phone 2 Voice signal can be transmitted.
