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.
Claims7
A method of performing periodic positioning in a mobile communication network, the method performed by a SLP (SUPL Location Platform) and comprising:
- receiving, from a Secure User Plane Location (SUPL) agent, a request message for periodic positioning of a target terminal (SET);
- sending, to the target terminal, a first Secure User Plane Location (SUPL) message that includes trigger type information related to the periodic positioning;
- receiving, from the target terminal, 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 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;
- sending, to the target terminal, a second Secure User Plane Location (SUPL) message that includes information related to a start time of the periodic triggered session and an interval for the periodic positioning;
- receiving, from the target terminal, a Secure User Plane Location (SUPL) POS INIT message to start the periodic positioning;
- exchanging, with the target terminal, positioning procedure messages for the periodic positioning;
- calculating a position of the target terminal based upon the exchanged positioning procedure messages;
- and
- reporting, to the SUPL agent, the calculated position of the target terminal,
- 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).
A method of performing periodic positioning in a mobile communication system, the method performed by an SLP (SUPL Location Platform) and comprising:
- receiving, from a target terminal, a Secure User Plane Location (SUPL) START message to start a periodic positioning session, the SUPL START message including information related to a period and a start time of the periodic positioning session;
- sending, to the target terminal, a Secure User Plane Location (SUPL) RESPONSE message that includes a session-id;
- receiving, from the target terminal, a Secure User Plane Location (SUPL) POS INIT message to start the periodic positioning according to the information included in the received SUPL START message;
- exchanging, with the target terminal, positioning procedure messages for the periodic positioning;
- calculating a position of the target terminal based upon the exchanged positioning procedure messages;
- and
- reporting, to the target terminal, the calculated position of the target terminal,
- 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).
