Abstract

PURPOSE:To receive incoming calls from both cordless and celullar phones in case the slave unit is in a cordless speech area. CONSTITUTION:A celullar reception section 105 capable of receiving signals from a cellular base station is added to a master unit. When the slave unit is in a cordless communications mode, the master unit monitors the incoming signals and position register signals from the cellular base station and informs them to the slave unit in the cordless communications using a cordless transmission section 103 when detecting the signals to the slave unit. Thus, the slave unit can respond to the incoming calls from both cordless and cellular phones and to the position registration.

Next, ID code exchange with the cellular base station in the cellular communication mode will be described. In the cellular communication mode, the control unit 314 of the slave unit controls the switching unit 307 to connect the cellular transmission unit 303 and the transmission sharing unit 305 and the cellular reception unit 304 and the reception sharing unit 306, and to set the standby state from the cellular base station. Become. The cellular base station periodically or randomly transmits location registration information to detect whether or not the slave unit is within the communicable range of the cellular base station. The slave unit includes an antenna 308 and a cellular reception unit. 30
4. When a radio wave including the cellular ID code information is received via the reception sharing unit 306 and the data processing unit 310, a response signal to the cellular ID code information is sent back to the cellular base station, and the cellular base station receives the response signal. This confirms that the slave unit is within the communicable range. Also, when the slave unit is in the cordless call area, a telephone number and an ID number for identifying each slave unit relating to the cellular system in the cordless communication mode before entering the cellular communication mode. Notify,
The parent device stores the information in storage unit 112.

Next, a description will be given of a cellular incoming call operation in the cellular communication mode. The slave unit includes an antenna 308, a cellular reception unit 304, a reception sharing unit 306, and a data processing unit 3.
When the control unit 314 receives an incoming call signal from the cellular base station through the control unit 10, the control unit 314 notifies the control unit 314 of the incoming call signal.
Via the antenna 308, the antenna 308, the cellular reception unit 304, the reception sharing unit 306, the audio circuit 309,
A two-way conversation is performed with the caller of the cellular telephone via the speaker 313.

Next, a call receiving operation from the cellular base station in the cordless communication mode will be described. The incoming call signal from the cellular base station reaches the cellular receiving section 304 via the antenna 308, but the switch 307 connects the cordless receiving section 302 and the receiving sharing section 306, and the cellular receiving section 304 and the receiving sharing section Since it is not connected to 306, control unit 314 cannot directly detect that there is an incoming call from the cellular base station. However, when there is an incoming call from the cellular base station in the cordless communication mode, the control unit 111 of the base unit transmits the incoming call signal from the cellular base station to the antenna 106, the cellular receiving unit 105, and the data processing unit 10.
8 and detects the incoming call to the slave unit, and when the incoming call signal is received, the telephone number or ID number of the incoming call signal and the telephone number of the slave unit stored in the storage unit 112 And an ID number, and if they are the same, a cellular incoming call is sent through the data processing unit 108, the cordless transmitting unit 103, and the antenna 106 to notify the slave unit that there is an incoming call signal from the cellular base station. Send a notification signal. Control unit 314 of slave unit
Receives a cellular incoming call notification signal via the antenna 308, the cordless receiving unit 302, and the receiving common unit 306, and notifies the user of the slave unit that there is an incoming call from the cellular base station by sound or display. Or the control unit 314
Switches the switching unit 307 to a connection in a cellular standby state,
An incoming call operation in a normal cellular communication mode is started. The control unit 111 of the base unit stops transmitting the incoming call notification signal when the cellular incoming signal from the cellular base station disappears or when a confirmation signal for the cellular incoming notification signal is received from the slave unit. .

Next, the operation of the location registration signal from the cellular base station in the cordless communication mode will be described. The control unit 314 cannot directly detect that there is an incoming call from the cellular base station, similarly to the case where the location registration signal from the cellular base station is an incoming call signal from the cellular base station. However, the control unit 111 of the master unit receives the position registration signal from the cellular base station via the antenna 106, the cellular receiving unit 105, and the data processing unit 108, and detects the position registration signal from the cellular base station to the slave unit. When the location registration signal is received, the telephone number or ID number in the location registration signal and the telephone number or ID number of the slave unit stored in the storage unit 112 are transmitted in the same manner as in the case of the incoming call signal. If they are the same, the data processing unit 108, the cordless transmitting unit 103, the antenna 1
A cellular location registration notification signal is transmitted to notify the slave unit via the mobile station 06 that there is a location registration signal from the cellular base station. The control unit 314 of the slave unit receives the cellular position registration notification signal via the antenna 308, the cordless reception unit 302, the reception sharing unit 306, and the data processing unit 310, controls the switching unit 307, and controls the cellular transmission unit 303 The connection is switched to the connection of the transmission sharing unit 305, the cellular reception unit 304, and the reception sharing unit 306, and the location registration operation with the cellular base station in the cellular communication mode is started. That is, the antenna 308, the cellular reception unit 304, the reception sharing unit 306, the data processing unit 3
10, a cellular position registration signal from the cellular base station is received, and a response signal to the signal is received by the data processing unit 3.
10. The transmission is returned to the cellular base station via the transmission sharing unit 305, the cellular transmission unit 303, and the antenna 308. Control unit 31
4 controls the switching unit 307 again when the position registration operation with the cellular base station is completed,
01 and the transmission sharing unit 305, and the connection of the cordless reception unit 302 and the reception sharing unit 306, and the operation in the normal cordless communication mode is started.

As described above, according to the radio telephone apparatus of the embodiment of the present invention, the cellular phone is provided with the cellular receiving section capable of receiving the incoming call signal and the location registration signal from the cellular base station. Can respond to both incoming cellular calls.

[0024]

As is apparent from the above embodiment, according to the present invention, when the cordless handset is in the cordless call area, by setting the cordless stand-by state, both cordless and cellular arrivals are made. It is possible to provide a wireless telephone device capable of responding to a call, and to respond to a location registration signal from a cellular base station. Further, the slave unit can be realized with the same volume and weight as the conventional one.
