Abstract

A SUPL enabled terminal, method and system for processing SUPL are discussed. According to one embodiment, the SUPL enabled terminal includes a processor to process a SUPL location platform (SLP) mode indicator received in a SUPL initiation message, the SLP mode indicator indicating whether the terminal is to operate according to a proxy mode or a non-proxy mode.

Claims

1. A method of processing a SUPL (Secure User Plane Location) request for a terminal that has performed roaming, the method comprising:

receiving a SUPL INIT message from a home SLP (SUPL Location Platform) entity, the SUPL INIT message including an indicator that indicates a proxy mode or a non-proxy mode;

checking the indicator to determine whether to establish a SUPL positioning session with a visited SPC (SUPL Positioning Center) entity; and

transmitting a SUPL POS INIT message to the visited SPC entity when the indicator indicates the non-proxy mode.

2. The method of claim 1, wherein if the indicator indicates the non-proxy mode, the method further comprises sending a SUPL authentication request to the home SLP entity before transmitting the SUPL POS INIT message to the visited SPC entity.

3. The method of claim 1, wherein if the indicator indicates the non-proxy mode, the transmitting step transmits the SUPL POS INIT message to the visited SPC entity to establish the SUPL positioning session with the visited SPC entity.

4. A terminal for processing a SUPL request upon roaming, 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 a proxy mode or a non-proxy mode, the transceiver further configured to transmit a SUPL POS INIT message to the visited SPC (SUPL Positioning Center) entity when the indicator indicates the non-proxy mode; and

a processor, in cooperation with the transceiver, configured to check the indicator to determine whether the indicator indicates the proxy mode or the non-proxy mode to establish a SUPL positioning session with the visited SPC entity.

5. The terminal of claim 4, wherein if the indicator indicates the non-proxy mode, the processor and the transceiver cooperate to send a SUPL authentication request to the home SLP entity before transmitting the SUPL POS INIT message to the visited SPC entity.
