A mobile station (6) equipped with a second transmitting / receiving means (20) for transmitting and receiving radio waves to and from a specific wireless station (7) and a third transmitting and receiving means (40) for transmitting and receiving radio waves to and from a specific wireless station (7). ) And a specific radio station (7) provided with a fourth transmission / reception means (50) for transmitting and receiving radio waves to and from the mobile station (6), and the first radio base station (5) of the base station (5). A mobile radio communication network (2) is constructed by the transmitting / receiving means (10) and the second transmitting / receiving device (20) of the mobile station (6), and the third transmitting / receiving means (40) of the mobile station (6). A mobile communication system comprising a short-distance communication network (2) for performing short-distance wireless communication by using a low-power radio wave with the fourth transmitting / receiving means (50) of the specific radio station (7). A second transmission / reception means (20) constituting the mobile radio communication network (2) and the short-range communication network The third transmission / reception means (40) is connected to the third transmission / reception means (40), and when the voice signal transmitted by the second transmission / reception means (20) is input, the third transmission / reception means (40) is switched to the transmission state. The audio signal transmitted from the second transmitting / receiving means (20) can be transmitted to the specific wireless station (7) via the third transmitting / receiving means (40), and the third transmitting / receiving means (40). When the voice signal transmitted by the above is input, the second transmission / reception facility (20) is switched to the transmission state, and the voice signal transmitted from the third transmission / reception means (40) is transmitted via the second transmission / reception means (20). A communication content transfer device in a mobile radio communication system that enables transmission to the base station (5). 3. The communication content transfer device (30) receives a voice signal input section () to which a voice signal transmitted from the base station (5) and converted and sent out from the second transmitting / receiving means (20) is input. 31), a voice detection unit (32) for the second transmission / reception unit that outputs a detection signal when the voice signal transmitted from the second transmission / reception unit (20) is input, and the voice detection unit (32) When outputting a detection signal, an audio signal output unit (33) for outputting the audio signal input to the audio signal input unit (31) to the third transmitting / receiving unit (40); and the audio detection unit (32). When the detection signal transmitted by the above is input, the third transmission / reception means (40) is operated to output a switching signal for switching the third transmission / reception means (40) to the transmission state. 34) and the specific radio A voice signal input section (35) to which a voice signal sent from the third transmitting / receiving means (40) transmitted and converted by (7) is inputted, and sent from the third transmitting / receiving means (40). Sound detecting section (36) for the third transmitting / receiving means for detecting a sound signal which is detected and outputting the detection signal, and the third transmitting / receiving means (40) when the detection signal sent by the sound detecting section (36) is input. Audio signal output section (3) for outputting the audio signal from the second transmitting / receiving means (20).
7) and a detection signal sent from the voice detection unit (36), a switching unit (38) for switching the second transmission / reception unit that outputs a switching signal for switching the second transmission / reception unit (20) to the transmission state. ), And when the voice detection section (32) outputs a detection signal, a switching command signal is output to the switching section (34) and the voice signal output section (31) outputs the voice signal to the voice signal output section (31). 33), and when the voice detection unit (36) outputs a detection signal, a switching command signal is output to the switching unit (38) to output the voice signal sent from the voice signal input unit (35) to the voice signal. The signal control unit (39) for performing signal control so as to output to the output unit (37).
