Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a driving system for a mobile radio telephone, and more particularly to a driving system for a mobile radio telephone in which a separable drive card is inserted into the main body of the telephone to drive the telephone.

In mobile phone systems such as car phones, connections are made via a wireless transmission path, so the telephone device requires a radio unit, which inevitably results in a large structure. is necessary.

Furthermore, since the device is often used in a small and vibrating moving body such as an automobile, it is necessary to use the simplest possible procedure for dialing and other call operations.

In addition, since telephones in the mobile radio telephone system are originally used on the move and are not meant to be installed in individual homes or offices, it is difficult to manage them in order to make them belong to individuals. It is necessary to take appropriate measures to prevent unauthorized use of

Figure 1 shows the configuration of an example of a conventional mobile phone.
Typically, the telephone unit 7 was composed of an antenna 1, a transmitting/receiving unit 2, a control unit 3, a transmitter 4, a receiver 5, and an operating unit 6 such as a dial switch.

The control unit 3 and the telephone unit 7 are connected by a multi-core curl cord, etc. The antenna 1, the transmitting/receiving unit 2, the control unit 3, the telephone unit 7
are integrated or connected by a cord.

For example, when using a car phone, bus/train phone, etc. in a small and vibrating moving object, or when carrying it with you, it is quite difficult to operate the operation part 6, which may lead to incorrect connections or during operation. There was a risk that safety would be compromised.

Furthermore, since the mobile telephone 8 can be moved anywhere, it may be difficult to manage it or to prevent fraudulent charges due to unauthorized use by others.

Furthermore, conventionally, mobile telephones have not been provided with services such as speed dialing, reversible dialing, or billing information display.

The present invention aims to simplify the operability of mobile radio telephones, enable management of the telephones, and prevent unauthorized use by others.Additional functions are also added, such as speed dialing and repertoire functions. The purpose is to enable services such as dialing and displaying billing information.

Next, the present invention will be explained with reference to the drawings.

FIG. 2 is a block diagram showing the configuration of one embodiment of the present invention, in which a handset 7' consisting of an antenna 1, a transmitting/receiving section 2, a control section 3, a transmitter 4 and a receiver 5, and a signal coupler 16 are shown. A mobile phone main body 8' consisting of a mobile telephone main body 8', a telephone driving card 15 consisting of a pushbutton 11, a memory/arithmetic circuit 12, a display 13, and a signal coupler 14 form one set.

(However, in this figure, the display of the battery in the telephone drive card 15 is omitted.

) The telephone drive card 15 is to be carried by the user at all times, and it is desirable that it has a card-like structure for convenient portability.

Furthermore, with current advances in electronics, it is easy to realize extremely thin devices.

As the display 13, it is suitable to use a liquid crystal display or the like which is inexpensive and consumes little power.

The signal couplers 14 and 16 may have a simple structure, such as a connector, in which conductive coupling is achieved by contacting metal pieces with each other, or may be optically coupled, such as by receiving the blinking of a light emitting diode or the like using a phototransistor. , a simple acoustic coupling method using a speaker and a microphone is also considered.

Furthermore, a method using magnetic coupling is also considered.

The user always carries the telephone drive card 15, and when he or she wishes to make a call, he or she presses the number of the other party using the pushbutton 11 of the first drive card 15 in advance.

This button 11 can be made up of 10 buttons corresponding to numbers O to 9, or it can be made up of 12 buttons corresponding to numbers O to 9 and two codes. If added, a button for specifying the type of calculation (+, -1x, ÷, etc.) may be provided, and other buttons may be provided as necessary.

The pressed number is temporarily stored in the memory/arithmetic circuit 12.

This number can be displayed on the display 13 and confirmed if necessary.

When the pressed card 15 is inserted into any specified position on the main body 8' of the mobile phone, the signal couplers 14 and 16 will be placed in opposing positions, and the numbers stored in the memory/arithmetic circuit 12 will be combined and the numbers stored in the memory/arithmetic circuit 12 will be connected. (the other party's number and the driving card holder identification number) are automatically connected to the signal coupler 14,1
6 to the control unit 3.

In addition, if the insertion operation of the drive card 15 and the off-hook function are linked, for example, if a switch is provided on the main body 8', this switch will operate at the insertion position of the drive card 15 and the off-hook state will be automatically established. Since the telephone number is sent out immediately, the calling operation is completed, and all that is left to do is to make a call using the handset 7'.

At this time, the driving card owner identification number is also sent to the exchange,
The driving cardholder who makes the call is charged regardless of the phone used.

In the case of an incoming call, simply inserting the drive card 15 puts the mobile telephone main body 8' into a receiving state.

1 The drive card owner's unique identification number stored in the storage/arithmetic circuit 12 of the drive card 15 is automatically transmitted to the control unit 3 through the signal couplers 14 and 16, so that the drive card owner can identify his or her own identification number. Receive calls to any mobile phone with a driving card inserted.

In this way, the driving card holder can make and receive calls at any one of an unlimited number of mobile radio telephones by inserting his card.

FIG. 3 is a block diagram showing the structure of a drive card according to another embodiment of the present invention, which makes the drive card easier to operate and allows provision of speed dial service.

That is, it is assumed that a semi-permanent memory circuit 22 and a permanent fixed memory circuit 23 are added to a memory/arithmetic circuit 21 including a temporary memory device as a memory/arithmetic circuit 12.
A plurality of destination telephone numbers are stored in advance in the semi-permanent storage circuit 22 by the operation.

When actually making a call, by pressing a specific short number using the button 11, the semi-permanent memory circuit 22
The specific partner number is read out to the storage/arithmetic circuit 21.

All that is left to do is to insert the drive card 15 into the mobile phone main body 8', as in the previous embodiment, and the call procedure is automatically completed.

As described above, according to the present invention, it is easy to provide a speed dial service.

FIG. 4 is a block diagram showing the configuration of a drive card according to still another embodiment of the present invention, in which the drive card is further multi-functional, and includes an arithmetic circuit 31 as a memory/arithmetic circuit 12, and a memory circuit 32 as a memory/arithmetic circuit 12. (including temporary memory, semi-permanent memory, and permanent fixed memory), and further includes a timer 33.

When the drive card holder uses the mobile radio telephone according to the above procedure, the timer 33 is activated at the start of use, and the already memorized destination number and the service zone number from the control unit obtained through the signal coupler 14.16 are activated. With the help of a timer 33, the arithmetic circuit calculates and displays the charges sequentially.

In order to minimize the discrepancy with the charges registered at the exchange, the timer 33 may be triggered by a billing start signal from the exchange.

In this case, since the fee is calculated using the most economical method possible, it does not necessarily match the amount registered at the official exchange, but it provides a fairly close approximation.

In the configuration shown in Figure 4, in addition to the above, there is a service that calls a party whose number is stored at a preset time (for example, after 10 minutes or 30 minutes) or repeatedly calls the same party at a certain time interval. It can provide services such as making calls.

Further, when the telephone is not in use, it can be used as a digital clock, and the pushbutton and arithmetic circuit 31 can be configured to be used as a calculator when the telephone is not in use.

FIG. 5 is a block diagram showing the configuration of a drive card according to another embodiment. In this embodiment, the drive card 15 is provided with a signal display coupler 41 that serves both as a signal coupler and a display.

In this case, for example, the decimal point of the numeric display of the display is used as a light emitting part, a corresponding light receiving part is provided on the phone body side, an optical coupler is constructed, and the decimal point is emitted at such a high speed that it cannot be detected with the naked eye. Blinks and transmits signals without affecting the display.

A plus or minus sign may be used instead of a decimal point.

It is also conceivable to provide a simple speaker as a signal coupler and use multi-frequency acoustic signals (audible frequency band or ultrasonic band).

In the mobile radio telephone drive system of the present invention, by separating the dial part from the main body as a drive card, the main body of the mobile device can be made simple with fewer operation sections, and the degree of freedom in installation location can be increased.

Since a call can be made simply by inserting the drive card, the call operation is simple and is ideal for mobile communications in small spaces such as in a vibrating automobile.

Only the driving card holder can make and receive calls, and unauthorized use by others can be prevented.

Since the fee is always charged to the driving card owner, it is possible to prevent damage caused by someone else's use of the card, and to avoid troubles related to billing.

Furthermore, the present invention makes it possible to provide services such as speed dialing and reversible dialing without any additional equipment, and it is also possible to display call charges and easily know the total call charges. .

Note that when not in use, the drive card can also be used as a digital clock or calculator.

Furthermore, according to the present invention, not only the telephone number is transmitted, but also the
By appropriately setting the types and combinations of pushbuttons, it is possible to transmit simple data messages, and also to display reception, making it possible to provide simple data services.

As described above, the present invention makes mobile radio telephones easier to use, contributes to expanding and improving serviceability, and encourages further development of mobile telephone systems.
