BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal information management technology in a wireless Internet system, and more particularly, to correct an error of subscriber information of a mobile communication terminal through interworking with an access information management system (hereinafter referred to as AIMS). An apparatus and method for managing terminal information in a wireless internet system.

There is a rapid development in the mobile communication field at home and abroad, and operators, equipment and terminal manufacturers are competitively developing advanced functions and additional services.

In addition to the two-way information service using SMS, the wireless Internet, which can transmit and receive a large amount of data in a more stable manner, is used.

The WAP (Wireless Application Protocol), which is a protocol used for the wireless Internet service, implements a function such as Netscape Navigator or Microsoft Internet Explorer, which is currently used as an Internet browser, in a mobile communication terminal. It is a protocol for processing a small screen mobile communication terminal by greatly reducing the amount of data to be processed.

The WAP is based on HTTP and HTML used in the Internet, and the Internet basically requests a desired information from a client's web browser to a web server and responds to the server. WAP is similar to the structure of the Internet for Internet service, and uses WAP gateway (WAP server) as a way to supplement the problem of wireless section processing, transmission / reception speed, and terminal problem.

The WAP service system searches for information of a desired origin server, that is, a Contents Provider (CP) server, through a WAP gateway in a mobile communication terminal which is a client. The WAP server converts a WAP request into an HTTP request or performs a reverse function.

Accordingly, the WAP server converts the WML document received from the mobile communication terminal into an HTML document and sends it to the desired CP server, and converts the response to WML in the CP server and sends the WML document to the mobile communication terminal.

FIG. 1 is a block diagram of a typical wireless Internet system including such a WAP gateway. The mobile communication terminal 10/1 to 10 / n, the WAP gateway 14, the web server 16, and the CP 18 are shown in FIG. It is composed.

A mobile communication terminal equipped with a WAP browser, for example, (10/1) accesses the WAP gateway 14 through the wireless Internet 12 and transmits a WAP request message, and the WAP gateway 14 transmits the HTTP request message. In this case, the request message is transmitted to the desired CP 18 through the web server 16.

That is, the WAP gateway 14 converts the WML document received from the mobile communication terminal 10/1 into an HTML document and transmits the converted HTML document to the desired CP 18. In addition, the WAP gateway 14 converts the response message of the CP 18 into WML and transmits the converted message to the mobile communication terminal 10/1.

When the mobile communication terminal 10/1 accesses the WAP gateway 14 and transmits a WAP request message, the information of the WAP request message includes various information about the mobile communication terminal 10/1 (hereinafter, UA field ( User Agent Field), and log information (MIN information, menu, UA field, etc.) remains in the WAP gateway 14.

Such information is managed in a DB (not shown) connected to the WAP gateway 14 (software upgrade, etc.), and the final managed UA field is transmitted to the CP 18 through the web server 16.

On the other hand, in recent mobile communication services, the 'number portability system' has been applied. The number portability system refers to a system that can arbitrarily change a mobile communication provider while maintaining a user's telephone number. For example, even when a user having a phone number of 01A-123-1234 changes from a first mobile communication provider to a second mobile communication service provider, the phone number can be kept as it is, and the phone number of a newly registered user In this case, it is easy to change the mobile operator by maintaining a unified operator identification number system such as 010-123-1234.

Due to such a number portability system, in the mobile service provider side, there is a need for systematic billing management for users having various identification numbers, for example, accurate call and wireless Internet usage fee calculation for UA.

However, in the conventional wireless Internet environment, since the subscriber information is extracted based on the UA field posted by the mobile communication terminal, an error in the subscriber information may occur when the wrong field information is uploaded due to an error of the WAP browser of the terminal.

In other words, if a wrong UA field is raised to the WAP gateway due to the lack of client-based authentication, for example, a terminal without a function for the 010 number, and a 010 subscriber, it should be raised to 010 as a normal or other mobile carrier. If the UA field is incorrectly raised, there is a problem that an error such as an information fee due to an incorrect UA field occurs.

The present invention is to solve the above-mentioned problems of the prior art, in extracting the subscriber information based on the UA field posted by the mobile communication terminal, the charging error due to the error of the mobile communication terminal to secure accurate subscriber information through AIMS And an apparatus and method for managing terminal information in a wireless Internet system capable of preventing a service error.
