PURPOSE: A system for intercepting a mobile communication terminal access of an IAGW(Internet Access Gateway) and a method therefor are provided to transmit an error message to a user if terminal type information is relative to predetermined type information designated for access interception, and to intercept an access for using a wireless Internet service, thereby realizing differentiated wireless Internet service charges. CONSTITUTION: A user terminal(110) accesses a proxy server(123) or an IAGW(127) of a mobile communication service system(120), and uses an Internet access service through a dedicated application. The mobile communication service system(120) enables a user to use a telephone service by using the user terminal(110). The proxy server(123) receives a web surfing request packet transmitted from the user terminal(110), sets a TCP connection with a contents server(130), downloads data, and transmits the data to the user terminal(110). The IAGW(127) permits an access of the terminal(110) if a type of the terminal is included in a notebook computer or a PDA, but intercepts the access if the type is included in a mobile communication terminal. The contents server(130) supplies data of the user terminal(110). |
