Hereinafter, an example of editing a phone number when an area code is included in a radio call number will be described with reference to the drawings.

In this case, the detection of the area code may be performed by checking whether the first digit of the telephone number displayed on the display of the pager is inputted with “0”. In addition, a method of confirming whether the area code data of the phone number displayed on the display unit and the stored area code match by storing the nation area code in advance in the corresponding memory unit may be used. In the description of the present invention, it should be noted that a method of checking whether the first number of the telephone number displayed on the display unit is "0" is described as an example.

First, as an example, in step 10, the wireless call number “27450084” is displayed on the display. If a call is made using this number in Seoul, the area code must be deleted. In this case, the arrow indicates the direction to be edited. In the case of the radio call number, editing is performed from the front. And underscores the working cursor. Therefore, in order to delete the area code, the user operates the delete key (CLR key) in the key input unit 13. Then, the first controller 10 detects the delete key and deletes the first " 0 " from the display 12. Then, as shown in the eleventh step, "27450084" is displayed on the display unit 12. The user then sees it and manipulates the delete key again. Then, the first control unit 10 detects the delete key and deletes the first "2" from the display unit 12.

In this case, a wireless call number without an area code is displayed, and when a call is made to another area by using the phone number, a telephone number "7450084" is displayed as an example in the fifteenth step. To insert an area code (eg 032), the user manipulates the numeric key "0". Then, the first control unit 10 detects this and inserts "0" into the display unit 12 to display "7450084" in step 16. The user then operates the numeric key "3". Then, the first control unit 10 detects this and inserts "3" into the display unit 12 to display "37450084" in step 17. Then, the user operates the numeric key "2". Then, the first control unit 10 detects this and inserts "2" into the display unit 12 to display "0327450084" as in the eighteenth step. If you try to dial using this number, you will operate the SEND key.

3C is a diagram illustrating a phone number editing process in a wireless call number according to an embodiment of the present invention.

In this case, the area code and the phone number are the same, but the area code is different. In the 20th step, the phone number "27450084" is displayed as an example. The user only needs to change this area code. If the area code is "32", only "3" needs to be added between "0" and "2". Therefore, by moving the cursor one space by using the shift key (#> key), "0 2 7450084" is displayed as in step 21. Thereafter, when the 3 key is manipulated, the controller detects it and the first control unit 10 inserts 3 to display "3 2 7450084" as in step 22. And if you try to dial using this number, you will operate the SEND key.

In this case, when the telephone number of CT-2 is displayed on the display unit 12, there are cases where the telephone number is directly input and the stored telephone number is read out from the first memory unit 11 and displayed. For example, as in step 25, the telephone number "7450084" is displayed, and if the user wants to change the telephone number to "7450085", the user must first delete the last "4". To do this, the user manipulates the delete key. Then, the first control unit 10 detects this and deletes the last " 4 " to display " 745008 " Then, the user manipulates the "5" key, and the first control unit 10 detects this and inserts "5" at the end of the display unit 12 to display "7450085" as in step 28.

And although not shown, if you want to delete all the phone numbers, the first control unit 10 by pressing the delete key continuously for a certain time to detect this and delete all the phone numbers at the same time.

Here, the detection of the predetermined time of the deletion key may be implemented through a timer (not shown) built in the first control unit, and the operation of the timer counts the time based on the time when the deletion key is pressed. The first controller 10 compares a time when the delete key is pressed with a preset time stored in the first memory unit 11 of the first controller 10 to determine whether the time when the delete key is pressed exceeds the preset time. Will be judged.

On the other hand, in the detailed description of the present invention has been described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.
