Location service-providing system and deferred location request service-providing method using previously computed location in location service-providing system
First Claim
1. A system for providing a location service, the system comprising:
- a Home-Secure User Plane Location (SUPL) Location Platform (H-SLP) for transmitting an SUPL Initiate (SUPL INIT) message including location information to a target SUPL Enabled Terminal (SET) according to a location service request from an SUPL AGENT, the location information including at least one of a previous position estimate and previous assistant data; and
the target SET for determining whether it is possible to provide the location service by reusing at least one of the local information in the SUPL INIT message and previously stored location information, when it is possible, determining position information by reusing at least one of the location information in the SUPL INIT message and the previously stored location information, and providing the SUPL AGENT with the position information.

Abstract
A location service-providing system and a method for providing a deferred location request service by using previously computed position estimates. In the system and the method, if an H-SLP transmits an SUPL INIT message including location information to a target SUPL Enabled Terminal (SET) according to a location service request from an SUPL AGENT, the location information including at least one of a previous position estimate and previous assistant data, the target SET receives the SUPL INIT message, determines whether it is possible to provide the location service by reusing at least one of the location information in the SUPL INIT message and previously stored location information, when it is possible, determining position information by reusing at least one of the location information in the SUPL INIT message and the previously stored location information, and providing the SUPL AGENT with the position information..

11. A method for providing a deferred location request service by using location information in a location service-providing system, the method comprising the steps of:
-
transmitting by a Home-Secure User Plane Location (SUPL) Location Platform (H-SLP) an SUPL Initiate (SUPL INIT) message including location information to a target SUPL Enabled Terminal (SET) according to a location service request from an SUPL AGENT, the location information including at least one of a previous position estimate and previous assistant data; and
determining by the target SET if it is possible to reuse at least one of the location information included in the SUPL INIT message and previously stored location information;
determining position information by reusing the at least one of the location information incuded in the SUPL INIT message and the previously stored location information, when it is possible; and
providing the SUPL AGENT with the position information. - View Dependent Claims (12, 15, 16, 17, 18, 19)

20. A system for providing a location service, the system comprising:
-
a Home-Secure User Plane Location (SUPL) Location Platform (H-SLP) for transmitting an SUPL Initiate (SUPL INIT) message according to a location service request from an SUPL AGENT, the SUPL INIT message including location information, a Quality of Position (QoP) of location information requested by the SUPL AGENT, and criteria for the location information, the location information including at least one of a previous position estimate and previous assistant data; and
the target SUPL Enabled Terminal (SET) for providing the SUPL AGENT with that satisfies the QoP and criteria included in the SUPL INIT message from among previously stored location information and the location information included in the SUPL INIT message. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)

28. A method by which a target Secure User Plane Location (SUPL) Enabled Terminal (SET) provides a deferred location request service by using previously computed position estimates in a location service-providing system, the method comprising the steps of:
-
receiving an SUPL Initiate (SUPL INIT) message including location information of the target SET, Quality of Position (QoP) of the location information, and criteria for selecting the location information, the location information including at least one of a previous position estimate and position assistant data; and
selecting usable location information which satisfies the QoP and criteria, from among the location information included in the SUPL INIT message and previously stored location information; and
providing an SUPL AGENT with the selected location information. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
