Abstract

PURPOSE:To improve the operability to the reinput of telephone numbers and to easily deal with the system change in regard of a cellular radio telephone set. CONSTITUTION:A microprocessor 2 decides the key input carried out through a key pad 1 and then performs the prescribed processing. A telephone number including an additional 'distance identification number applied in a specific distance' is inputted and a '1' key is pushed in a digit key group 5 after a function key 6. Thus the 'distance identification number applied in a specific distance' is replaced with that stored in a nonvolatile memory 3. Meanwhile the 'distance identification number applied in a specific distance' is used exclusive for decision when a '2' key is pushed after the key 6 and after the input of a telephone number serving as a 'distance identification number'. Furthermore a 'distance identification number applied out of a specific distance' is stored in the memory 3 with push of a '3' key.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improving the operability of inputting a distance identification number peculiar to a cellular radio telephone system.

[0002]

2. Description of the Related Art In the cellular radio telephone system of Nippon Telegraph and Telephone Corporation, as shown in P48 of "TELEPHONICA", published by Magazine House Co., Ltd. Since the charges are different, "030", 1 within 160km
If it exceeds 60 km, "040" will be added to the beginning. If the other party is over 160 km and he / she makes a call by mistake with the telephone number with "030" added, the line will not be connected, and the user will start again with "040". I had to make a call again by re-entering the telephone number with "."

[0003]

As described above, in the prior art, when a person outside the specified distance is erroneously added with the "distance identification number within the specified distance" at the beginning, a telephone call is made. If it happens, the user has to make a call again by re-inserting the telephone number prefixed with "distance identification number outside specific distance".

An object of the present invention is to identify the distance at the beginning of a telephone number being input by a simple key operation, instead of re-entering all digits of the telephone number to which the "distance identification number outside a specific distance" is added. It is intended to improve the operability by replacing the number with the "distance identification number within the specific distance" to the "distance identification number outside the specific distance".

Another object of the present invention is to rewrite a distance identification number for discriminating "distance identification number within a specific distance" and a distance identification number to be replaced as "distance identification number outside a specific distance". By storing the data in the non-volatile memory, it is possible to easily deal with the change of the "distance identification number" by the cellular radio telephone system and improve the expandability.

[0006]

To achieve the above object, a microprocessor is used to store an input telephone number in a memory, and the telephone number is added to the head of the telephone number by a key operation from a keypad. This allows you to replace a specific number with another number.

Further, in order to achieve another purpose,
Using a microprocessor, by operating the keys on the keypad, the entered telephone number can be stored in the non-volatile memory as the "distance identification number within the specified distance" or "distance identification number outside the specified distance". It is a thing.

[0008]

The key input is controlled by the microprocessor. When there is a key input, the microprocessor activates the function assigned to it. If the entered key combination activates the function that replaces the specific number added to the beginning of the telephone number with another number, the beginning of the telephone number is the "distance identification number within the specified distance". Or not. If it is the "distance identification number within the specified distance", the "distance identification number outside the specified distance" stored in the non-volatile memory is called and the "distance within the specified distance" is input. Distance identification number ”. After that, the user can make a call again by simply pressing the key for making a call.

Further, by making it possible to change the "distance identification number within the specific distance" and the "distance identification number outside the specific distance" stored in the non-volatile memory, the cellular radio telephone system can be changed. It is possible to easily cope with the change of the "distance identification number within the specific distance" and the "distance identification number outside the specific distance".

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram showing an embodiment of the present invention. 1 is a keypad, 2 is a microprocessor, 3
Is a rewritable non-volatile memory, 4 is a display for displaying the input telephone number and the like, 5 is a group of digit keys for inputting the telephone number and the like, 6 is a function key for executing the defined function, Reference numeral 7 denotes a call key that activates call processing.

FIG. 2 is a control flowchart of this embodiment.

3 and 4 show display examples of the embodiment.

In FIG. 1, when there is a key input from the keypad 1, the microprocessor 2 discriminates the input key or key combination and performs a predetermined process defined for each key. If necessary, the contents of the non-volatile memory 3 are read out, and alphanumeric characters are displayed on the display 4.

Next, the function key 6 is followed by the keypad 1
By pressing the "1" key in the digit key group 5 above, the "distance identification number" added to the beginning of the entered telephone number is determined and the "distance identification number within the specified distance" is determined. By replacing the "distance identification number outside the specific distance" and pressing the "2" key in the digit key group 5, the "distance identification number within the specific distance" to be discriminated is stored, and the digit is stored. The control operation of the embodiment will be described with reference to FIG. 2 in the case where the memory of the "distance identification number outside the specific distance" is set by pressing the "3" key in the key group 5. ..

While the power is on, the microprocessor 2 constantly monitors key inputs from the keypad 1.

When a user of the cellular radiotelephone makes a call to a cellular radiotelephone that is more than a specific distance away by using a telephone number with "distance identification number within specific distance" added at the beginning (display example) 3), "distance identification number within specific distance" is replaced with "distance identification number outside specific distance"
You need to call again with the phone number you replaced.

In this case, if the user presses the "1" key in the digit key group 5 after the function key 6 (step 10 in FIG. 2) (step 11 in FIG. 2), the telephone number is input. It is determined whether it has been completed (step 12 in FIG. 2). If the telephone number has been input, it is determined whether or not the "distance identification number" added to the beginning matches the "distance identification number within the specific distance" stored in the nonvolatile memory 3 ( 2 step 13). If they match, the "distance identification number within the specific distance" added to the beginning of the telephone number is replaced with the "distance identification number outside the specific distance" stored in the nonvolatile memory 3 (Fig. 2). Step 14, the display example is FIG. 4). Then, the user of the cellular radiotelephone can make a redial by using the telephone number to which the "distance identification number outside the specific distance" is added just by pressing the transmission key 7.

Next, the memory of the "distance identification number within the specific distance" and the "distance identification number outside the specific distance" to the non-volatile memory 3 is performed by the following operation.

If the "2" key in the digit key group 5 is pressed after the function key 6 (step 15 in FIG. 2),
It is determined whether or not the telephone number to be the "distance identification number" has been input (step 16 in FIG. 2). If it has been input, it is stored in the non-volatile memory 3 as the "distance identification number within the specific distance" (step 17 in FIG. 2).

If the "3" key in the digit key group 5 is pressed after the function key 6 (step 18 in FIG. 2),
It is determined whether or not the telephone number to be the "distance identification number" has been input (step 19 in FIG. 2). If it has been input, it is stored in the non-volatile memory 3 as "distance identification number outside specific distance" (step 20 in FIG. 2).

[0022]

As described above, according to the present invention, when making a call with a telephone number to which a wrong "distance identification number" is added to a partner who is separated by a certain distance or more, This makes it easy to re-enter the phone number and prevents input errors when entering the phone number.
