Abstract

A terminal and method and system for processing SUPL are discussed. According to one embodiment, the invention provides a method of processing a SUPL request for a terminal that has performed roaming, the method comprising: receiving a SUPL INIT message from a home SLP entity, the SUPL INIT message including an indicator that indicates whether a home SLP entity uses a proxy mode or a non-proxy mode; checking the indicator to determine whether the home SLP operates in the proxy mode or the non-proxy mode; and selectively performing authentication with the home SLP entity based on the checking result indicating whether the home SLP entity operates in the proxy mode or the non-proxy mode.

Claims

1. A method of processing a SUPL request for a terminal that has performed roaming, the method comprising:

receiving a SUPL INIT message from a home SLP entity, the SUPL INIT message including an indicator that indicates whether a home SLP entity uses a proxy mode or a non-proxy mode;

checking the indicator to determine whether the home SLP operates in the proxy mode or the non-proxy mode; and

selectively performing authentication with the home SLP entity based on the checking result indicating whether the home SLP entity operates in the proxy mode or the non-proxy mode.

2. The method of claim 1, wherein the authentication is skipped while another operation is performed, if the home SLP entity operates in the proxy mode.

3. The method of claim 1, wherein the authentication is performed if the home SLP entity operates in the non-proxy mode.

4. The method of claim 3, wherein the authentication is performed by transmitting a SUPL AUTH REQ message to the home SLP entity and receiving a SUPL AUTH RESP message from the home SLP entity, so that authentication between a visited SLP entity and the terminal can be performed.

5. A terminal for processing a SUPL request, the terminal comprising:

a transceiver configured to receive a SUPL INIT message from a home SLP entity, the SUPL INIT message including an indicator that indicates whether a home SLP entity uses a proxy mode or a non-proxy mode; and

a processor configured to cooperate with the transceiver and to check the indicator to determine whether the home SLP operates in the proxy mode or the non-proxy mode, the processor configured to selectively perform authentication with the home SLP entity based on the indicator indicating whether the home SLP entity operates in the proxy mode or the non-proxy mode.

6. The terminal of claim 5, wherein the processor skips the authentication and instead performs another operation, if the home SLP entity operates in the proxy mode.

7. The terminal of claim 5, wherein the processor performs the authentication if the home SLP entity operates in the non-proxy mode.

8. The terminal of claim 7, wherein the processor performs the authentication by transmitting, via the transceiver, a SUPL AUTH REQ message to the home SLP entity, and receiving, via the transceiver, a SUPL AUTH RESP message from the home SLP entity so that authentication between a visited SLP entity and the terminal can be performed.
