Method for positioning target terminal while protecting privacy of user thereof
First Claim
1. A method performed by a SUPL Location Center (SLC) for providing location information of a target Secure User Plane Location (SUPL) Enabled Terminal (target SET), the method comprising:
- receiving a location request message from a requester;
transmitting a SUPL INITiation (SUPL INIT) message by using a first session IDentifier (ID) to the target SET, the first session ID includes a SET ID of the target SET in a SET session ID;
transmitting a Positioning DATA (PDATA) message by using a second session ID to a SUPL Positioning Center (SPC), the second session ID is different from the first session ID for secure connection between the SLC and the SPC;
receiving a positioning result of the target SET from the SPC; and
transmitting the positioning result to the requester.

Abstract
A method of providing location information of a target Secure User Plane Location (SUPL) Enabled Terminal (target SET) while protecting privacy of a user of the target SET in a Home-SUPL Location Center (H-SLC) providing the location information of the target SET, and the H-SLC, are provided. The method includes receiving a location request message from a requester, transmitting an SUPL INITiation (SUPL INIT) message by using a first session IDentifier (ID) to the target SET, the first session ID including a real ID of the target SET, transmitting a Positioning DATA (PDATA) message by using a second session ID to the Home-SUPL Positioning Center (H-SPC), the second session ID including a pseudo-ID for secure connection between the H-SLC and the H-SPC, receiving a positioning result of the target SET from the H-SPC, and transmitting the positioning result to the requester.
