Abstract

PROBLEM TO BE SOLVED: To provide a dialing method for portable telephone, with which dialing to another area is easily enabled. SOLUTION: A database is set by a memory and the contrast list of substitutive codes of network companies at respective places in the world, international codes, the codes of nations and telephone systems is saved on the database. The telephone numbers of callee are saved in a portable telephone at random. When it is judged by a CPU that a telephone system to be linked is different from an original telephone system, the substitutive code and international code of the corresponding network company are read from the database on the basis of the telephone system to be linked, and the substitutive code and international code of the corresponding network company are automatically added before the telephone number of a callee, and displayed on a display device. Therefore, a user can easily dial to the other area by a portable telephone.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of dialing a mobile phone by using a random access memory (RAM) to simplify dialing of a mobile phone between world regions.

[0002]

2. Description of the Related Art Cellular phones have the advantages that they are small in volume, complete with functions, and their prices are decreasing daily.
Preferred by humans. Humans use mobile phones to instantly communicate with friends or business partners. Therefore, the mobile phone can make a call more easily and faster than the conventional wired phone.

[0003]

At present, the mobile phone is improving and replacing the inconvenience of the conventional wired phone, but has the following drawbacks. When a user makes a contact by using a mobile phone while traveling abroad, the international code (Internat
You must know the ional access code) and the national code. You cannot call unless you dial the international code, national code, and mobile phone number in this order. The above work is unavoidable, which is inconvenient. Therefore, it is necessary to solve the difficulty of the operation process and the waste of time when the user uses the mobile phone while traveling abroad. Therefore, an object of the present invention is to eliminate various difficulties in using a mobile phone while traveling overseas and to provide a mobile phone dialing method capable of easily dialing another area.

[0004]

According to the method of dialing a mobile phone according to the present invention, a database is set in the memory of the mobile phone, and a substitute code, an international code or a national code of a network company around the world is set in the database. And save the contrast list of the phone system, save the recipient's phone number randomly on the mobile phone, CP of the mobile phone
When U determines that the telephone system to be linked is different from the original telephone system, U reads the substitute code and international code of the corresponding network company from the database saved in memory based on the linked system, and the telephone number of the recipient Before the above, the substitute code and international code of the corresponding network company are automatically added and displayed on the display device of the mobile phone.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. According to the mobile phone dialing method according to the embodiment of the present invention, a database is set in the memory 11 of the mobile phone as shown in FIG. The database contains substitute codes for international network companies, international codes,
Save country code and telephone system contrast list. Randomly save the recipient's phone number on the mobile phone. When the CPU 13 determines that the telephone system to be linked is different from the original telephone system, the substitute code and international code of the corresponding network company are stored from the memory 11 of the mobile phone, that is, the newly saved database, based on the linked telephone system. read. afterwards,
Based on the corresponding code, the code is automatically added before the recipient's telephone number, and the telephone number is displayed on the display device 15 of the mobile phone. Therefore, the user can easily talk with the recipient only by dialing the recipient's telephone number. Therefore, the steps of the dialing method for overseas calls are effectively simplified, and drawbacks such as complicated operation steps and time consuming when a user uses a mobile phone during an overseas trip are improved.

As shown in FIG. 1, the CPU 13 of the mobile phone
Is linked to the nearest base via the receiving / transmitting circuit 16 and the antenna 17. The CPU 13 receives the telephone signal transmitted from the base and broadcasts the telephone signal through the speaker 18. At the same time, the CPU 13 is the microphone 1 of the mobile phone.
The voice signal transmitted from the terminal 9 is received, the received voice signal is converted into a telephone signal, and the telephone signal is transmitted to the base via the receiving / transmitting circuit 16 and the antenna 17. Further, the CPU 13 displays the processed data on the display device 15 and reads the saved data from the memory 11. When the user touches the button key 110 of the mobile phone, the user can input characters or codes.

As shown in FIG. 2, this method uses a random access memory (RAM) to simplify the method of dialing a mobile phone to another area. The user starts the mobile phone and randomly saves the recipient's phone number.
CPU of mobile phone when using mobile phone in overseas travel
13 performs the following steps.

(A) First, it is identified whether the telephone system to be linked is different from the original telephone system saved in the database. The following steps are performed according to the identification result. When not identifying the linked telephone system, the cell phone dials the original telephone number saved in the database.

(A) Find the nearest base, link to the local telephone system, and confirm the current location. (C) Based on the substitute code of the telephone system, the substitute code and international code of the corresponding network company are read from the database of the memory 11 of the mobile phone. (D) With the corresponding code, the substitute code and the international code are automatically added before the telephone number of the recipient, and the telephone number is displayed on the display device 15 of the mobile phone.

[0010]

[Effects of the Invention] When using a mobile phone during an overseas trip, the recipient's phone number is randomly saved in the mobile phone and the CP
U identifies and reads from the database in memory the code corresponding to the different regional (national) telephone systems and automatically adds the corresponding code in front of the recipient's telephone number. Therefore, the method of dialing a mobile phone to other areas is simplified. Therefore, the present invention improves the disadvantages such as complicated operation steps and time consumption when a user uses a mobile phone while traveling abroad, and is convenient and practical. The present invention can be applied not only to a mobile phone but also to a personal digital assistant (PDA) having the function of a mobile phone.
