Abstract
A positioning method in a SUPL based position information (positioning) system, and particularly a positioning method capable of variously efficiently performing an area-based positioning (location tracking) performed by a location server or a mobile communications terminal when the location server and the mobile communications terminal respectively manage triggers generating the area-based positioning.
Claims22
An area-based positioning method for a mobile communications system wherein said system is conformed to the existing Open Mobile Alliance SUPL standard, the method performed by a server and comprising:
- sending a SUPL INIT message to a SET in order to initiate a SUPL procedure for an area event triggered session, based upon a positioning request for the SET, the SUPL INIT message comprising a session-id, an intended positioning method, a proxy/non-proxy mode indicator, and a trigger type indicator;
- sending a SUPL TRIGGERED RESPONSE message to the SET in response to receiving a SUPL TRIGGERED START message from the SET in order to start an area event triggered session with the SET,
- wherein the SUPL TRIGGERED START message comprising comprises a session-id, a location-id, and SET capabilities, and the SUPL TRIGGERED RESPONSE message comprises at least one of a session-id, a positioning method, trigger parameters, and location identifiers of an area specified for the area event triggered session;
- receiving a SUPL POS INIT message from the SET to start the area event triggered session, when a comparison performed by the SET of a current area-id and the location identifiers of the area specified for the area event triggered session indicates that positioning of the SET is to be executed;
- exchanging position procedure messages with the SET during the positioning session to calculate actual positioning information indicating longitudinal and latitudinal values of the SET;
- sending a SUPL REPORT message to the SET, the SUPL REPORT message including the session-id and the calculated actual positioning information of the SET, in order to allow the SET, which operates in SET-based mode, to compare the calculated actual positioning information with the trigger parameters;
- and
- receiving a SUPL REPORT message from the SET, the SUPL REPORT message including the session-id and the calculated actual positioning information of the SET, if the calculated actual positioning information indicates that the trigger parameters are satisfied by the SET.

- receiving a SUPL INIT message from a server in order to initiate a SUPL procedure for an area event triggered session, based upon a positioning request for the SET, the SUPL INIT message comprising a session-id, an intended positioning method, a proxy/non-proxy mode indicator, and a trigger type indicator;
- receiving a SUPL TRIGGERED RESPONSE message from the server in response to sending a SUPL TRIGGERED START message to the server in order to start an area event triggered session with the SET,
- wherein the SUPL TRIGGERED START message comprising comprises a session-id, a location-id, and SET capabilities, and the SUPL TRIGGERED RESPONSE message comprises at least one of a session-id, a positioning method, trigger parameters, and location identifiers of an area specified for the area event triggered session;
- sending a SUPL POS INIT message to the server to start the area event triggered session, when a comparison performed by the SET of a current area-id and the location identifiers of the area specified for the area event triggered session indicates that positioning of the SET is to be executed;
- exchanging, with the server, positioning procedure messages to calculate actual positioning information indicating longitudinal and latitudinal values of the SET;
- calculating the actual positioning information when the SET operates in SET-based mode;
- comparing the calculated actual positioning information with the trigger parameters after receiving a SUPL REPORT message from the server, the SUPL REPORT message including the session-id and the calculated actual positioning information of the SET;
- and
- sending a SUPL REPORT message to the server, the SUPL REPORT message including the session-id and the calculated actual positioning information of the SET, if the calculated actual positioning information indicates that the trigger parameters are satisfied by the SET.
