Periodic positioning method in mobile communications system
First Claim
Patent Images
1. A method of performing periodic positioning in a mobile communication system, the method performed by a target terminal and comprising:
- receiving, from an SLP (SUPL Location Platform), a first Secure User Plane Location (SUPL) message that includes trigger type information related to periodic positioning, and the first SUPL message also includes a session-id, a positioning method, and an SLP mode;
sending, to the SLP, a Secure User Plane Location (SUPL) START message to start a periodic triggered session with the SLP for the periodic positioning, the SUPL START message including at least a session-id, lid, and target terminal capabilities, wherein the target terminal capabilities are used to select an intended positioning method to be used for the periodic triggered session;
receiving, from the SLP, a second Secure User Plane Location (SUPL) message that includes information related to at least one of a start time of the periodic triggered session and an interval for the periodic positioning;
performing a SUPL positioning procedure based upon the information included in the SUPL START message;
repeating the SUPL positioning procedure based upon the information included in the SUPL START message; and
receiving, from the SLP, a SUPL END message after a last positioning result is reported to a SUPL Agent from the SLP,wherein all of the above steps are based on Secure User Plane Location (SUPL) technology that provides periodic positioning through a user plane, andwherein the SLP and the target terminal support Internet Protocol (IP).

Abstract
A positioning method in a SUPL based position information system, and more particularly, a method for performing periodic positioning capable of processing a periodic positioning request by a location server or a periodic positioning request by a mobile communications terminal when the location server and the terminal respectively manage a trigger generating the periodic positioning, are discussed.

7. A method of performing periodic positioning in a mobile communication system, the method performed by a SUPL Enabled Terminal (SET) and comprising:
-
sending, to an SLP, a SUPL START message to start a periodic positioning session, the SUPL START message including session-id, lid, SET capabilities, and information related to at least one of a start time of a periodic triggered session and an interval for periodic positioning; receiving, from the SLP, a SUPL RESPONSE message that includes a session-id; performing a SUPL positioning procedure based upon the information included in the SUPL START message; repeating the SUPL positioning procedure based upon the information included in the SUPL START message; and sending, to the SLP, a SUPL END message after performing a last SUPL positioning procedure, wherein all of the above steps are based on Secure User Plane Location (SUPL) technology that provides periodic positioning through a user plane, and wherein the SLP and the target terminal support Internet Protocol (IP). - View Dependent Claims (8, 9, 10, 11, 12)
