DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 2 is a diagram for explaining the concept of the mobile phone and the external device of the present invention. In the figure, 1 is a mobile phone, 2 is a vehicle-mounted external device, 3 is a fixed external device, 4
Is a base station. The mobile phone 1 can be freely carried by a person and makes a call by receiving a radio wave from the base station 4 or transmitting the radio wave to the base station 4 at an arbitrary moving position. In addition, the vehicle-mounted external device 2 is mounted on the vehicle, and the fixed external device 3 is installed in a house or the like.
By connecting the mobile phones 1 to 3 respectively, it is possible to talk with the base station 4. In this case, each external device 2,
No. 3 automatically receives a call from the other party without holding a handset like a normal telephone, makes a call, and automatically enters a standby state at the end of the call. In addition, the external device supplies power to the main body of the mobile phone to secure a long call and standby time.

FIG. 1 is a block diagram of an embodiment of the present invention. The mobile phone 1 is provided with an antenna 11, a transmission / reception unit 12, a voice processing unit 13, a control unit 14, a battery 15, a changeover switch 16 for switching between electricity and an external power source, a speaker 17, and a microphone 18, and these are used as usual mobile phones. Although it constitutes a telephone, it further has a connection connector 19 in a part of its housing, and the voice processing unit 13, the control unit 14, and the changeover switch 16 are connected to the connection terminals, respectively.

The external devices 2 and 3 include a voice processing unit 21, a control unit 22, a power supply unit 23, a speaker 24, and a microphone 25.
And a connection connector 26 to be connected to the connection connector 19 of the mobile phone 1, and a voice processing unit 21, a control unit 22, and a power supply unit 23 are connected to the connection terminals thereof, respectively. The control unit 22 is configured to be capable of automatically receiving an incoming call and automatically ending a call.

FIG. 3 is an external view showing an example of the portable telephone 1 and an external device, here an external device 3 for installing a house. The external device 3 is provided with a flexible microphone 32, an external speaker 33, a microphone volume 34, a speaker volume 35, a power source display 36, an automatic incoming call display 37, etc. in a housing 31. Further, a connector portion 38 for connecting the mobile phone 1 is provided in a part of the housing 31, and the mobile phone 1 can be attached and detached. In this configuration example, in a state where the mobile phone 1 is connected to the external device 3, it is possible to automatically receive an incoming call and automatically end a call, and to talk with hands free.

In the mobile phone having the above-described structure, when the mobile phone is used alone for communication, the antenna 11 receives the radio wave from the base station 4, passes through the transmission / reception unit 12, and goes on-hook by the control unit 13 to make a call line. Are connected. When the call line is connected, the voice of the other party is output from the speaker 17 through the transmitting / receiving unit 12 and the voice processing unit 13.
The input from the microphone 18 is transmitted to the base station 4 from the antenna 11 via the voice processing unit 13, the transmission / reception unit 12, and the like.

On the other hand, when a telephone call is made by connecting the external device 2 or 3, the call line is connected in the same manner as in the case of the mobile phone alone, and when the call line is connected, the transmitting / receiving unit 12,
The signals that have passed through the voice processing unit 13 are connected to the connectors 19, 2
6, the speaker 24 outputs the other party's voice through the voice processing unit 21 of the external device. In addition, the input of the microphone 25 is passed through the voice processing unit 21 and the connection connectors 25 and 19, and then the voice processing unit 13 and the transmission / reception unit 12 of the mobile phone 1.
Via the antenna 11 to the base station 4. still,
At this time, the battery 15 of the mobile phone 1 is not used, and power is supplied from the power supply unit 23 of the external device.

When a call is made using the external devices 2 and 3, the control unit 22 of the external device can perform automatic incoming call control and automatic call end control. That is, in the case of automatic incoming call,
The call signal from the base station is transmitted and received by the transmission / reception unit 12 of the mobile phone.
Detection is performed via the control unit 14, and conversely, an on-hook instruction is sent to the control unit 14 of the mobile phone 1. On the other hand, in the case of automatic call termination, the RBT (ring back tone) transmitted when the other party ends the call via the mobile phone,
Conversely, send an on-hook instruction to the control unit 14 of the mobile phone,
Perform end call processing.

FIG. 4 is a call connection flow when automatic call termination and automatic call termination are performed using an external device. That is, the mobile phone 1 receives the incoming call signal from the base station 4, and transmits the incoming call response signal to the base station 4. Base station 4 selects an empty channel,
A call channel is designated and a line test is performed. After confirming that the call channel is usable, a call signal transmission instruction is transmitted to the mobile phone 1. The mobile phone 1 sends a calling signal to the base station 4, detects the RBT from the base station 4, and detects the external device 2.
3. Send RBT detection signal to 3. The external devices 2 and 3 send an on-hook instruction to the mobile phone 1, and the mobile phone 1 sends an on-hook signal to the base station 4 to establish a call state.

When the other party ends the call, the base station 4 sends an RBT, and when the external devices 2 and 3 detect the RBT, they send an on-hook instruction to the mobile phone 1. The mobile phone 1 sends an on-hook signal to the base station 4, and the base station 4
After confirming the disconnection of the call channel, the call ends.

[0015]

As described above, according to the present invention, since the portable telephone is provided with the input / output terminal which can be connected to the external device, the portable telephone can be used as the external device when riding in the vehicle or in the house. By connecting to, it is possible to automatically receive and end calls. Further, there is an effect that power can be supplied from the external device to the mobile phone to enable a long-term call, and the call and the standby state can be maintained unless the power of the external device is turned off. Further, the external device of the present invention can expand the usage of the above-mentioned mobile phone.
