According to a control signal, a transceiver 20 for transmitting and receiving a voice signal to and from the cordless handset 16, and a control signal for the mobile phone 10, the PHS 12, and the general public network are input and output. For the incoming call from the communication means, a control signal for switching is output to the switching unit 18, and when notifying the cordless handset 16 of an incoming call, a control signal for the incoming call notification and the incoming call is output to the transmitting / receiving unit 20. And a control unit 22.

The control unit 22 includes a transmission / reception unit 20, a switching unit 18,
Control the mobile phone 1 via the control line.
0 and PHS12 are controlled. The transmission / reception unit 20 performs wireless communication with the cordless telephone handset 16. The switching unit 18 controls the mobile phone 10 and the PHS under the control of the control unit 22.
The switching between the voice signal from the telephone number 12 and the general public telephone line is performed. When calling from the cordless handset 16, the control unit 22 includes the switching unit 18, the transmission / reception unit 20,
Alternatively, by outputting a control signal to the PHS 12,
By inputting a predetermined code, the mobile phone 10, P
A call from the HS 12 can be made.

The portable telephone 1 is attached to the cordless telephone base unit 16.
0 or PHS12, and the mobile phone 10 or PHS12
By relaying the incoming call to the cordless handset 16, the incoming call to the mobile phone 10 or the PHS 12 can be received by the cordless handset 16.

In this embodiment, one mobile phone and one PHS are implemented, but there is a configuration in which the number is further increased. In addition, in this configuration, the charging function of the mobile phone or the PHS is built in the cordless telephone base unit, so that the charging can be performed simultaneously with the mobile phone or the PHS connected.

Next, the operation of the embodiment of the present invention will be described with reference to FIG. FIG. 3 is a sequence diagram when an incoming call arrives at the mobile phone of the present invention. This sequence example is an example in a case where there is an incoming call to the mobile phone 10. Control unit 22
Detects that there is an incoming call to the mobile phone 10 by the control signal. The control unit 22 outputs a control signal to the transmission / reception unit 20 and notifies the cordless handset 16 of an incoming call. Cordless cordless handset 16 performs ringing with a radio wave from transmitting / receiving section 20. The control unit 22 outputs a control signal to the switching unit 18, and an audio signal from the mobile phone 10 is connected to the transmitting / receiving unit 20. The cordless handset 16 notifies the control unit 20 of the off-hook via the transmission / reception unit 20. When detecting the off-hook from cordless handset 16, control unit 20 relays the incoming call to mobile phone 10. Cordless cordless handset 16 notifies control unit 20 of the on-hook.
When detecting the on-hook, the control unit 20 notifies the on-hook and ends the call.
