[Prior Art] Conventionally, when a mobile radio telephone such as a car telephone or a mobile telephone is purchased or leased, it is difficult to remember the telephone number of the telephone station when the telephone is first used.

For this reason, mobile radio telephones that have the function of displaying their own telephone number are often used.

Normally, the telephone number used in a car phone, etc. includes a phone number for call processing necessary for making/receiving calls, and a phone number used when a general user calls the car phone, etc. from a general line. There are different types. Of these, the latter is the phone number that general users use; if the phone number for call processing and the phone number dialed from the general line are different systems, the phone number dialed from the general line is the phone number of your own station. Is it necessary to display it as

Conventionally, the display telephone number was determined by the system depending on the relationship between the call processing telephone number and the display telephone number, so the display telephone number was determined from the call processing telephone number based on the relational formula. I was looking for it.

Therefore, only the phone number for call processing is recorded in a car phone, etc., and the phone number for display is not recorded. It was calculated based on the phone number.

On the other hand, the number of subscribers to car telephones, etc. has increased rapidly in recent years, and it has become necessary to change the numbering system of car phone numbers used by general users accordingly. It's coming. Along with this, it is also necessary to change the relational expression between the telephone number for call processing and the telephone number for display.

However, conventional car telephones and the like have the disadvantage that the relational expression between the telephone number for call processing and the telephone number for display is configured by firmware fixed to the device, and cannot be easily changed.

The present invention has been made in view of the above-mentioned drawbacks, and by storing the call processing telephone number and the display telephone number independently, rewriting due to a change in the number system can be easily performed using an operating means. The purpose of the present invention is to provide a mobile radio telephone such as a car telephone that can perform the following functions.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a mobile radio telephone having a function of displaying the telephone number of its own station, which includes an operation means for inputting data, and a display means for inputting data. a non-volatile memory for storing a telephone number for display and a telephone number for call processing; an instruction means for giving an instruction signal to change to a telephone number writing mode when writing the telephone number of the local station; and a telephone number for display and call processing; A telephone number for the station is set according to the contents of the non-volatile memory, a call is made and received using the telephone number for call processing, a telephone number of the own station is displayed using the telephone number for display, and the instruction signal is and a processing means configured to change to a telephone number writing mode by input data from the operating means only when the input data from the operating means is given, so that the telephone number can thereafter be written into the nonvolatile memory by the input data from the operating means. Preferably, the nonvolatile memory is an electrically rewritable nonvolatile memory, or the operating means is a dial key and a function key provided on the handset.

[Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a car telephone according to an embodiment of the present invention.

In the drawing, l is a handset, and dial keys and function keys 10 are used as operation means.
and a display section 11 using liquid crystal.

Reference numeral 2 denotes a main body of the mobile device, in which a memory 3 and a processing section 4 are provided, and both are connected by a bus. Here, as the memory 3, an electrically rewritable non-volatile memory E" PROM 3 is used. In this memory 3, a telephone number for display and a telephone number for call processing are stored independently. Stored.

Further, as the processing unit 4, a microprocessor (CPU
) is used to set each telephone number, perform call/arrival operations using the telephone number, display processing of the own telephone number, and read and write the contents of the memory 3. The handset 1 and the processing section 4 are connected via a serial interface, and exchange key data and display data.

Furthermore, the mobile device main body 2 is provided with a test terminal 5 for connecting a test link 6, and is connected to the processing section 4. This test link 6 is used when changing the processing section 4 to the telephone number writing mode.

Next, the operation of the car phone having the above configuration will be explained.

■Incoming call operation When received data is sent via the wireless unit (not shown), the processing unit 4 reads the telephone number for call processing from the memory 3 and compares it with the telephone number in the received data. . If the telephone numbers match as a result of the comparison, a predetermined call receiving operation is performed, such as sending an incoming call response signal to the outside via the wireless section together with the transmission data.

■Call operation Enter the phone number of the other party using the dial key lO on handset 1.
Input by. The input telephone number is input to the processing unit 4 via the serial interface. Processing section 4
In addition to creating transmission data based on the input data, the phone number for call processing is read from the memory 3 and sent to an external device via the wireless section along with the outgoing data in order to notify which car phone is making the call request. Send to.
