Description

SERVICE METHOD FOR UNSTRUCTURED SUPPLEMENTARY SERVICE DATA INFORMATION OF MOBILE COMMUNICATION DEVICE}

The present invention relates to an additional service data information service method of a mobile communication terminal, and in particular, by storing unique additional service data (USSD: Unstructured Supplementary Service Data) for each mobile carrier in a SIM card so as to provide a list thereof. In addition, the present invention relates to an additional service data information service method of a mobile communication terminal that enables a user to easily find a desired service in a supplementary service list even if the SIM card is changed (also a carrier).

In general, a subscriber identity module (SIM) is a small printed circuit board that must be inserted into every GSM-based mobile phone when applying for subscription, which includes subscriber details, security information, and memory for personal phonebooks. have. In addition, the SIM card contains a microchip that can store information and encrypt voice and data transmissions, making it impossible to eavesdrop on calls, and also storing data that can identify the caller's identity to network service providers. have.

Therefore, in the case of the GSM terminal, the operator changes when the SIM is changed, so that the user cannot know what USSD service is provided for each operator. That is, since the user must find and use the USSD service currently provided by the SIM provider through a separate promotional material, it is difficult to use the more effective USSD service.

Therefore, the present invention has been created to solve the above-mentioned conventional problems, in the GSM terminal using the SIM card stores information for the use of additional service data (USSD) for each operator in the SIM card, the USSD information An object of the present invention is to provide an additional service data information service method of a mobile communication terminal, which enables a user to directly select a desired service menu from a list.

The present invention for achieving the above object, through the SIM (Subscriber Identity Module) card control menu, the output of the list of additional service (USSD) stored in the SIM card and outputting a sub-menu for a new additional service update A first step; If a supplementary service update menu is selected in the submenu, checking whether there is a newly updated service from a base station; A third step of downloading the service list to the SIM card and outputting the service list together with the existing service list when the check result is a newly updated service; And a fourth step of selecting the additional service item desired by the user from the output service list and immediately performing the corresponding additional service.

The present invention provides detailed information on various USSD services according to a SIM operator through a SIM service, so that the user can easily know USSD commands by presenting various information and usage methods for the USSD service. Make it easy to acquire.

In addition, the present invention, if there is a USSD command that is not embedded in the SIM card, so that it can be checked and upgraded online, so that it can be easily serviced even for a new command not embedded in the SIM card.

In addition, in the conventional case, the service request is made by directly pressing the USSD service code, but the present invention has the effect of improving the convenience of the user by directly selecting a desired service from the USSD service list and requesting the service.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described.

1 is a flowchart illustrating a method of serving supplementary service data (USSD) information of a mobile communication terminal according to the present invention. First, a user may enter a USSD service information menu through a SIM service menu (SAT).

Through the SIM service menu, a user may obtain USSD information provided by a SIM operator. In this case, it is easy to include a field for storing a USSD service list in the SIM card, and to add a menu for outputting USSD service information to the SIM service menu as described above.

There are several types of USSD services, for example, when you press the # + 1 + 1 + 1 + # button to perform the 'language setting switching' function, and when you press the # + 1 + 0 + 0 + # button, the billing information ( It is to perform a function for receiving AOC: Advice Of Charge, etc., and to provide the type of service and code information corresponding thereto that can be provided through the USSD service menu.

Accordingly, the user may obtain the type and code information of the USSD service output through the menu, and directly press the code button to request the service. In addition, the present invention improves the user's convenience by directly selecting the desired service from the service list to perform the service directly.

That is, the function of storing the USSD service list in the SIM card as described above allows the user to easily know the information about the USSD service type and code information provided by each operator.

For example, when the first operator (Hong Kong CSL) SIM is inserted, the # + 1 + 1 + 1 + # code is a code for performing a language setting function, and the user can change it to Chinese or English, and the USSD comes after The sentence is sent in the changed language, and the # + 1 + 0 + 0 + # code provides the USSD service for downloading the ringtone.

However, when a second SIM (Wind) SIM is inserted, the # + 1 + 1 + 1 + # code is a function for providing billing information to the user, even if the service types for the same code are different as described above. Is easily identified through the USSD service menu.

On the other hand, when the SIM card is released for the first time, all available USSD service information up to that point is included, but the USSD service information added while the user purchases and uses the upgrade must be upgraded. To be processed.

That is, when the user outputs the USSD information menu and selects a menu for upgrading the new USSD information and presses the 'OK' button, a command for checking whether there is a USSD command not embedded in the SIM card is sent to the base station using the USSD code. send.

Accordingly, the base station responds to the USSD code. If new USSD information is received, the base station writes the new USSD information in the USSD information field of the SIM card, and outputs a USSD list including the upgraded information. If there is no USSD information, only the existing USSD information list is displayed.

Accordingly, when the user selects a desired service from the USSD information list and presses the 'confirmation' button, the corresponding USSD code is transmitted to the base station to receive the USSD service.

That is, in the conventional case, information on a mobile station (ME) for the USSD service is not provided. However, in the present invention, even if the SIM is changed, the terminal may easily know the USSD information through the SIM service.

As described above, the method of providing additional service data information of the mobile communication terminal according to the present invention stores a unique additional service data (USSD) for each mobile communication provider in a SIM card so that the list can be provided. Even if you change (even if you change the operator) it is effective to find the desired service in the list of additional services to easily receive services.
