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 a first message or a second message should be transmitted to the home SLP entity; and transmitting the first message or the second message to the home SLP entity according to a result of the checking step.

Claims

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

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

checking, by the terminal, the proxy/non-proxy mode indicator to determine whether a predetermined message should be transmitted to the home SLP entity, wherein the predetermined message is a SUPL AUTH request which is used to perform authentication between a visited SLP entity and the terminal; and

transmitting, by the terminal, the SUPL AUTH request to the home SLP entity when the proxy/non-proxy mode indicator indicates that the home SLP entity is in the non-proxy mode according to a result of the checking step.

2. A terminal that processes a SUPL (Secure User Plane Location) request, the terminal comprising:

a transceiver configured to receive a SUPL INIT message from a home SLP entity, the SUPL INIT message including a proxy/non-proxy mode indicator that indicates whether the 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 proxy/non-proxy mode indicator to determine whether a predetermined message should be transmitted to the home SLP entity, wherein the predetermined message is a SUPL AUTH request which is used to perform authentication between a visited SLP entity and the terminal,

the transceiver further configured to transmit the SUPL AUTH request to the home SLP entity when the proxy/non-proxy mode indicator indicates that the home SLP entity is in the non-proxy mode.
