It consists of the following sections.

[Industrial application field]

The present invention relates to a car phone terminal device that combines a car phone and a pager terminal.

A car phone allows calls to be made via a wireless line between the phone installed in the car and a general phone, and a pager terminal is a small, portable device that is used only for making calls using a buzzer. Some configurations or configurations that can receive and display simple messages are known.

[Conventional technology]

For example, as shown in FIG.
The base stations 31, 32, 33 correspond to the wireless zones so that a plurality of wireless zones 41, 42, 43 are formed adjacent to each other.
are arranged, and each is connected to the switching control station 34. Further, the switching control station 34 is connected to a telephone 1i 135 including an exchange accommodating a general telephone subscriber 36.

Each base station 31, 32, 33 has communication channels 44°, 45.
46 and a control channel 47.48.49, and a call to a motor vehicle 37.38.39 equipped with a telephone as a mobile station is made via the control channel 47.48.49, and when the call is answered, designated call channel 44
45 and 46, a call is made with a subscriber accommodated in the telephone network 35.

The base stations 31, 32, and 33 are, for example, 870 to 885M.
Hz band transmission frequency, car phone is 925-940
The transmission frequency is in the MHz band, and the audio signal is FM modulated.
Control information such as call information is FSK modulated and transmitted. Car as a mobile station 37.38.39
It identifies its own location based on the wireless zone number notified by the control channel with the highest reception level, and registers its own location via the control channel when it identifies that it has moved between wireless zones. Therefore, the car is 37°38.39
Since the current location of the car can be identified on the exchange control station 34 side, when there is an incoming call, a calling signal is sent from the base station of the wireless zone to which the car belongs, and by answering the call, the call is terminated. A channel will be assigned and a call will be made. When making a call, the telephone number of the other party is sent via the control channel, and the call is made through the communication channel designated by the base station.

In addition, pager terminals make wide area calls without registering their current location, and the calling address is, for example, 2
It is FSK modulated in the 80 MHz band and transmitted at a speed of 200 b/s. In the case of a message display system, messages are transmitted at a speed of 400 b/s.

When a pager terminal is called, a call is made from a nearby telephone to a prearranged telephone number, or in the case of a message display service, a call is made using the displayed telephone number.

[Problem that the invention seeks to solve]

If you subscribe to a car phone service, you will be able to answer incoming calls while riding in your car, but if you get off the car and are away from your car, you will not be able to answer calls. On the other hand, if you subscribe to a pager, you can receive calls from any location within the service area. However, if a call is received while riding in a car, it is necessary to get out of the car and answer the call using a nearby telephone.

Therefore, it is conceivable to subscribe to both a car phone and a pager so that users can respond to calls even when they are in or out of the car. However, since the subscriber number of a car phone is different from the subscriber number of a pager, the caller often does not know whether the caller is in a car or not, and cannot use which subscriber number to make the call. I'm wondering if it's the right thing to do.

For example, if you make a call using your car phone's subscriber number and you are away from your car, you will not be able to answer the call because you will not be able to understand the call. Also, if you are in a parked car when you make a call using your pager's subscriber number, you will be able to answer the call immediately using your car phone, but if you are driving a car, you will not be able to make a call while the car is in motion. Because it is dangerous, the vehicle must stop and make a call to answer the call.If the vehicle cannot stop,
After driving to a place where you can stop, you will make a response call. Therefore, even if a car phone is installed, the pager terminal must be turned on, and if you are driving when you are called using the pager's subscriber number, you cannot answer the call immediately. There was a drawback that it could not be done.

The object of the present invention is to automatically make a call from a car phone by calling a pager terminal.

[Means to solve the problem]

The automobile telephone terminal device of the present invention uses a pager adapter to which a pager terminal is attached, and will be explained with reference to FIG.

The pager adapter 2 is equipped with a car phone 1 and a pager terminal 3 and is connected to the car phone 1. A first detection section 5 consisting of a switch etc. that detects that the pager terminal 3 is attached and starts power supply from the power supply section 4, a second detection section 6 that detects call information of the pager terminal 3, and a second detection section 6 that detects call information of the pager terminal 3; The call control section 7 automatically causes the mobile phone 1 to make a call based on the call information detected by the detection section 6.

[Effect]

The pager adapter 2 is connected to the car phone 1,
When the pager terminal 3 is attached to the pager adapter 2, the first detection section 5, which mechanically or electrically detects the attachment, starts supplying power from the power supply section 4 to each section.

Then, there is a call from the pager terminal 3, and the second detection unit 6 detects the call signal and the call information including the telephone number and the like in the message.

In this case, depending on the configuration of the pager terminal 3, the message received by the pager terminal 3 may be transferred to the detection section 6.

Based on this call information, the call control unit 7 performs control to automatically make a call using a preset telephone number or automatically make a call based on the phone number in the received message. Even if it occurs while driving, you can automatically respond.

Furthermore, when leaving the car, the pager terminal 3 must be removed and carried with you.

[Examples] Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram of an embodiment of the present invention, in which 11 is a car phone, 12 is a pager adapter, 13 is a pager terminal, 14 is a power supply unit, 15.16 is a first . In the second detection section, 17 is a memory, 18 is a comparison section, 19 is a tone generation section, 20 is a control section, and 21 is a transmitting/receiving section. The memory 17, the comparison section 18, and the tone generation section 19 cause the call control section 7 in FIG. has been done.

In this embodiment, the pager terminal 13 is configured to be able to receive a call and a message including a telephone number, and the memory 17 has registered therein an arbitrary number of other party's telephone numbers that are permitted to be automatically dialed. This registration can be configured to be performed using, for example, a dial key of the car telephone 11.

The pager adapter 12 is connected to the control unit 20 of the car phone 11, but it can also be connected by providing a connection terminal similar to the handset connection terminal of the car phone 11. The tone generating section 19 of the pager adapter 12 generates an off-footer signal for automatic dialing and a tone signal corresponding to the telephone number of the other party, and applies them to the control section 20 to cause automatic dialing.

When the pager terminal 13 is attached to the pager adapter 12, the first detection section 15 mechanically or electrically detects the attachment. For example, the detection unit 15 may have a structure in which contacts are mechanically closed when the pager terminal 13 is attached, or a switch such as a transistor may be closed by the power supply of the pager terminal 13. can. Note that even when the pager adapter 12 is connected to the car phone 11, the car phone 11
It is possible to make outgoing calls and answer incoming calls using the handset.

When the first detection section 15 detects that the pager terminal 13 is attached, the power supply section 14 starts supplying power to each section based on the detection signal.

This power supply unit 14 may be configured with a battery or may utilize the power supply of the car phone 11.

Pager terminal 13 attached to pager adapter 12
When called, the calling signal is transferred to the second detecting section 16, and subsequently the received message is transferred. The second detection unit 16 detects the transferred calling signal and the comparison unit 1
8 is activated, and the telephone number in the next forwarded received message is added to the comparison section 18 and compared with the telephone number registered in the memory 17.

If there is a matching telephone number, the matching signal and the telephone number are transferred to the tone generating section 9, since this is a telephone number for which automatic calling is permitted. The tone generator 19 thereby:
An off-hook signal and a tone signal indicating a telephone number are applied to the control section 20 of the automobile telephone 11, and the automobile telephone 11 is caused to make an automatic call.

Therefore, even if a call from the pager terminal 13 occurs while driving a car, the call can be made automatically and answered safely without the need for manual call operation.

Also, if the telephone number is not registered in the memory 17, or if the registered telephone number and the telephone number in the received message do not match, the call is from an unexpected subscriber and the call will not be made automatically. In this case, an alarm sound may be sounded to indicate that automatic dialing will not be made in response to the call.

When the pager terminal 13 is used only for calling, the comparator 18 uses the detection signal from the second detector 16 to add the telephone number read from the memory 17 to the tone generator I9 so as to automatically make a call. It turns out. In this case, an automatic call will be made to a specific telephone number registered in advance.

〔Effect of the invention〕

As explained above, the present invention includes a first detection section 5 that starts power supply from the power supply section 4 upon detection of attachment of the pager terminal 3, and a second detection section 6 that detects call information of the pager terminal 3. , a pager adapter 2 comprising a call control unit 7 that automatically makes a call from the car phone 1 based on call information.
By attaching the pager terminal 3 to the pager adapter 2 while riding in a car,
In the case of an incoming call to the car phone l, the car phone l can answer the call, and in the case of a call to the pager terminal 3, an automatic call is made according to the call information, making it possible to answer the call. . Therefore, there is an advantage that it is possible to safely answer a call from the pager terminal 3 while driving a car.
