Abstract

A method for performing an SUPL-based triggered location service, comprising: sending a pause message for a triggered session to a server, starting the triggered session for a triggered location service with the server; and sending a end message to the server if a condition added to the triggered session is satisfied during pause of the triggered session.

Claims

1. A method for performing an SUPL-based triggered location service, comprising:

receiving a pause message for a triggered session from a target terminal, after starting the triggered session for a triggered location service with the target terminal; and

sending a end message for the triggered session to the target terminal, if a condition added to the triggered session, is satisfied during pause of the triggered session.

2. The method of claim 1, wherein the condition is included in a triggered session request message to be received.

3. The method of claim 1, wherein the condition is included in SUPL INIT message to be received.

4. The method of claim 1, wherein the condition is a time condition about the triggered session.

5. The method of claim 1, wherein the condition includes start time of the triggered session, the number of location measurements and a location measuring period.

6. The method of claim 1, wherein the condition includes start time and stop time of the triggered session.

7. The method of claim 5, wherein the condition is determined to be satisfied, by analogizing a stop time of the triggered session based on the start time of the triggered session, the number of the location measurements, and the location measuring period, and by checking whether a present time corresponds to the stop time.

8. The method of claim 1, wherein the end message for the triggered session comprises at least one of a session-id parameter, and a status code parameter.

9. The method of claim 1, wherein the end message for the triggered session is an SUPL END message.

10. The method of claim 1, further comprising sending an MLP TLREP message to the target terminal having requested the triggered location service if the condition added to the triggered session is satisfied.

11. A method for performing an SUPL-based triggered location service, comprising:

sending a pause message for a triggered session to the server, after starting the triggered session for a triggered location service with a server;

receiving a end message for the triggered session indicating ending of the triggered session from the server, during pause of the triggered session; and

deleting information relating to the triggered session, in response to the received end message.

12. The method of claim 11, wherein the end message for the triggered session comprises at least one of a session-id parameter and a status code parameter.

13. The method of claim 11, wherein the end message is an SUPL END message.

14. The method of claim 11, wherein the information relating to the triggered session comprises at least one of ‘

session-id’

, ‘

trigger_type, ‘

posmethod’

, and ‘

trigger_params’

.

15. A method for performing an SUPL-based triggered location service, comprising:

sending a pause message for a triggered session to a server, starting the triggered session for a triggered location service with the server; and

sending a end message to the server if a condition added to the triggered session is satisfied during pause of the triggered session.

16. The method of claim 15, wherein the condition is included in a triggered session request message to initiate the triggered session.

17. The method of claim 16, wherein the triggered session request message is an SUPL INIT message.

18. The method of claim 15, wherein the condition is a time condition about the triggered session.

19. The method of claim 15, wherein the condition includes start time of the triggered session, the number of location measurements, and a location measuring period.

20. The method of claim 15, wherein the condition includes start time and end time of the triggered session.

21. The method of claim 19, wherein the condition is determined to be satisfied by analogizing a stop time of the triggered session based on the start time of the triggered session, the number of the location measurements, and the location measuring period, and by checking whether a present time corresponds to the stop time.

22. The method of claim 15, wherein the end message comprises at least one of a session-id parameter and a status code parameter.

23. The method of claim 15, wherein the end message is an SUPL END message.
