FIG. 5 illustrates a process of requesting location information of a user terminal using a WAP browser, for example, a KTF Unified Navigator browser in a mobile communication terminal. Referring to FIG. If the mobile communication terminal requests its location information to the service server 322 (step 500), the service server 322 requests the location of the own phone number (MDN) to the LBSP 320 (step 502). .

The LBSP 320 requests authentication of a target terminal (i.e., its own terminal) that has requested location information from an authentication gateway (eg, Juice G / W of KTF) (step 504), and receives an authentication response from the authentication gateway. (Step 506).

If authentication fails, the LBSP 320 sends authentication failure information to the service server 322 (step 508), and the service server 322 sends a failure message to the mobile communication terminal that requested the location information. Transmit (step 510).

On the other hand, if the authentication is successful, the authentication response may include the IMSI and the terminal model information of the terminal requesting the location information, the LBSP 320 is a MPC (318) for the location information request including the MDN, IMSI and terminal model information (Step 512).

When there is a location information request from the LBSP 320, the MPC 318 requests network information of the target terminal to the DGMLC 316 and receives response information (step 514).

The MPC 318 receives information on whether the corresponding terminal is in the 2G network or the 3G network from the DGMLC 316, and requests the location information from the PS 330 when the target terminal is in the 3G network ( Step 516). The location information request includes an IMSI so that the PS 330 may perform an authentication process of the target terminal.

Thereafter, the PS 330 transmits response information indicating that the session is ready for session establishment with the target terminal to the MPC 318 (step 518).
