1 is a block diagram of an electronic device of an artificial intelligence cellular phone making an international call according to the present invention;

2 is a flowchart of a dialing method for making such an international call.

The present invention relates to a dialing method for making international calls in an artificial cellular phone.

Cellular phones, due to their portability, versatility and low unit price, have recently become popular worldwide as social or business communication devices. Moreover, compared with the conventional wireless telephone, the cellular phone has the advantage of having convenience and portability in outdoor places. However, cellular phone functionality is not yet perfect. For example, if the international access code of the telephone call location area is different from the code preset in the phone book by the user, the phone number stored in the phone book of the cellular phone cannot be used. In the case of international roaming, successful cellular phone calls are only possible after the user knows the international access code, the domestic code, the area code and the telephone number of the called party. That is, the user must dial the international access code, the domestic code, the local mode and the number in order. In view of the above, international calls by cellular phones are inconvenient. In another case of talking to several people located in different countries, the corresponding international access code and the inspection process for its operation are more complicated and time consuming. This is very annoying to cell phone users and causes inconvenience. Thus, the above problem related to international calls by cellular phones has to be solved. Moreover, it is desirable to provide a dialing method for making international calls in a convenient and effective manner to overcome the disadvantages of the prior art.

It is therefore an object of the present invention to store the system codes of a number of global network companies and their international access codes in a conversion table of a database of memory of a cellular phone;

Storing a plurality of telephone numbers of other called subscribers in the telephone directory of the database;

Retrieving the telephone number stored in the telephone book according to the name of the called party to be dialed;

Determining whether the system code received from an adjacent telephone company in the location area calling this telephone number is different from the system code stored in the telephone book; Otherwise, retrieving an international access code corresponding to the system code of the telephone number retrieved from the telephone book by the international access code retrieved from the revision table according to the system code received from the local telephone company in the call location area;

A dialing method for making an international call in an artificial cellular phone, comprising automatically dialing a telephone number having a corrected international access code.

The above and other objects, features and advantages of the present invention will become apparent from the following detailed description of the invention with reference to the accompanying drawings.

The present invention relates to a dialing method for making an international call using an artificial cellular phone. An artificial intelligence cellular phone is provided with a system code provided by many international telephone companies, a conversion table formed in a database of the memory 11 for storing international access codes, and formed in this database to provide information about other called parties. Construct a phone book containing a number of phone numbers (including international access codes, country codes, area codes and numbers). When the user uses the cellular phone, the central processing unit (CPU) 13 determines whether the phone book mode is operating. If it does not work, the CPU 13 receives the input telephone number and sends it directly. When the phone book mode is in operation, the CPU 13 retrieves the phone number of the called party who is dialing from the phone book according to the name selected by the user. Next, the CPU 13 determines whether or not the system code received from the neighboring or local telephone company in the calling location area is different from the system code stored in the phone book when storing the telephone number to be called. The CPU 13 indicates and transmits the telephone number retrieved from the telephone directory on the display of the cellular phone, if the system code received from the local telephone company is different from the system code storing this telephone number in the telephone directory. Accesses the revised table of memory 11, which retrieves the international access code associated with the system code of the local telephone company, and retrieves the international access code of the telephone number retrieved from the telephone book according to the system code received from the local telephone company. Replace with an access code, then the phone number with the correct international access code In summary, the cellular phone user can select from the telephone number a preferred telephone number to dial in. Thus, the system of the present invention corresponds to a system code received from a local telephone company with a corrected international access code. It automatically inserts and dials the phone number retrieved from the phone book, which is a convenient and practical design.

1 is a block diagram of an electronic device of an artificial intelligence cellular phone making an international call according to the present invention. The cellular phone CPU 13 may establish a connection with the base station via the transceiver circuit 16 and the antenna 17. Thus, the CPU 13 can receive a telephone signal from the base station. The received signal is converted into sound waves and then amplified by the speaker 18. Also, sound waves from the microphone 19 are received by the CPU 13. The received sound wave is converted into a telephone signal by the CPU 13 and then transmitted to the base station through the transceiver circuit 16 and the antenna 17. Moreover, the CPU 13 transmits the processed data to the display 15 and stores it in the memory 11. In addition, the CPU 13 can access data stored in the memory 11. In addition, the CPU 13 may receive alphabet data input by the user to the keypad 110.

FIG. 2 is a flowchart of a dialing process for making an international call by the CPU 13 of the cellular phone when the cellular phone goes to standby during a call during international roaming.

In step (1), the process determines if the cellular phone has entered the phonebook operating mode. If not, the process directly receives the input telephone number and then proceeds to step (5). If so, the process receives data of the called party, such as a name, to retrieve the relevant telephone number from the telephone directory (step (2)). In step (3), the process retrieves the system code sent by the neighboring or local base station of the network company and then establishes a connection with it. Next, the cellular phone accesses the revision table of the memory 11 to retrieve the international access code corresponding to the system code received from the local base station, and then the international access code of the location area for dialing this telephone number stores the telephone number. Determine if it is equal to an international access code. If the process proceeds to step 4, and if it is not the same, the process proceeds to step 4 after the international access code of the telephone number to dial is replaced with the international access code retrieved from the revision table. In step 4, the process issues a phone number with the correct international access code to dial on the display 15 of the cellular phone. Next, in step 5, the process determines whether the telephone number has been dialed. If not determined, the process returns to step (1).

In summary, when the cellular phone user enters the phone book operation mode and a phone number to be dialed is selected from the phone book, the CPU 13 receives from a network company in the location area which accesses the revision table of the memory 11 and calls the phone. Retrieve the corrected international access code corresponding to the generated system code. Phone numbers with a correct international access code are dialed automatically. This is a convenient and practical design. By using this method, the inconvenience of talking with several people in different countries, waste of time regarding the corresponding international access code and the retrieval process of its operation, and the like are substantially solved.

Moreover, the database of cellular phones is updated regularly. This cellular phone can also be implemented as a personal digital assistant (PDA) with cellular phone functionality.

Although the present invention has been described in terms of specific embodiments, those skilled in the art will recognize that various modifications and changes can be made without departing from the spirit and scope of the invention.

The present invention can facilitate international calls in the artificial intelligence system.
