Location service providing system and method
First Claim
1. A location service providing system comprising:
- a target SUPL (Secure User Plane for Location) Enabled Terminal (SET) for;
storing a positioning method determined in an initialization stage of a location service according to a location service request, wherein the positioning method is one of a Mobile Station (MS)-assisted Assisted Global Positioning System (A-GPS) method and an MS-based A-GPS method;
determining in a location calculation process whether the stored positioning method is available, when the target SET receives a new location service request, after storing the positioning method in the initialization stage;
providing the stored positioning method to a Home-SUPL Location Platform (H-SLP), if it is determined that the stored positioning method is available; and
requesting for re-determination of a positioning method to the H-SLP, if it is determined that the stored positioning method is unavailable.

Abstract
A location service providing system and method the system includes target SUPL (Secure User Plane for Location) Enabled Terminal (SET) determines and stores a positioning method in an initialization stage of a location service according to a triggered location service request, determines in a location calculation process whether the stored positioning method is available, provides the stored positioning method if it is determined that the stored positioning method is available, and requests for re-determination of a positioning method if it is determined that the stored positioning method is unavailable: and a home-SUPL location platform (H-SLP) which provides the location service using the stored positioning method if the stored positioning method is provided from the target SET or provides the location service by re-determining a positioning method with the target SET if the re-determination of a positioning method is requested.

15. A location service providing system comprising:
-
a Home-Secure User Plane for Location (SUPL) Location Platform (H-SLP) for providing the location service using a stored positioning method, if the stored positioning method is provided from a target SUPL Enabled Terminal (SET), when the target SET receives a new location service request, receiving a re-determination request of the positioning method from the target SET, re-determining a new positioning method of the target SET, and providing the location service by using the new positioning method, wherein the stored positioning method is determined in an initialization stage of the location service according to a previous location service request, and the positioning method is one of a Mobile Station (MS)-assisted Assisted Global Positioning System (A-GPS) method and an MS-based A-GPS method. - View Dependent Claims (16, 17, 18, 19, 20)
