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 a Secure User Plane Location based (SUPL-based) triggered location service, comprising:

receiving, by a server from a target SUPL Enabled Terminal (SET), a pause message for a triggered session for the SUPL-based triggered location service, after starting the triggered session with the target SET to provide a location service;

pausing the triggered session based on the pause message; and

sending, by the server, a triggered session end message for the triggered session to the target SET, if a condition added to the triggered session is satisfied while the triggered session is paused,

wherein the triggered session end message for the triggered session is a SUPL END message.

2. The method of claim 1, further comprising:

before the receiving step, receiving a triggered session request message including the condition so as to start the triggered session.

3. The method of claim 1, further comprising:

obtaining location information of the target SET through the triggered session.

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 a start time of the triggered session, the number of location measurements and a location measuring period.

6. The method of claim 5, wherein the condition is determined to be satisfied, by analyzing 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.

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

8. The method of claim 1, wherein the triggered session 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, further comprising sending a message to a SUPL agent that has requested the start of the triggered session, said message indicating status information regarding the condition.

10. A method for performing a Secure User Plane Location based (SUPL-based) triggered location service, comprising:

sending, by a target SUPL Enabled Terminal (SET) to a server, a pause message for a triggered session for the SUPL-based triggered location service, after starting the triggered session with the server to provide a location service;

while the triggered session is paused based on the pause message, receiving, by the target SET, a triggered session end message for the triggered session indicating ending of the triggered session from the server; and

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

wherein the triggered session end message is a SUPL END message.

11. The method of claim 10, wherein the triggered session end message for the triggered session comprises at least one of a session-id parameter and a status code parameter.

12. The method of claim 10, wherein the information relating to the triggered session comprises at least one of ‘

session-id’

, ‘

trigger_type’

, ‘

posmethod’

, and ‘

trigger_params’

.

13. A method for performing a Secure User Plane Location based (SUPL-based) triggered location service, comprising:

establishing a triggered session for the SUPL-based triggered location service with a server to provide a location service;

sending, by a target SUPL Enabled Terminal (SET) to the server, a pause message for the established triggered session;

while the triggered session is paused based on the pause message, determining, by the target SET, whether a condition added to the triggered session is satisfied; and

sending, by the target SET to the server, a triggered session end message for the paused session when the condition added to the triggered session has been satisfied,

wherein the triggered session end message is a SUPL END message.

14. The method of claim 13, wherein the condition is included in a triggered session request message to initiate the triggered session.

15. The method of claim 14, wherein the triggered session request message is an SUPL INIT message.

16. The method of claim 13, wherein the condition is a time condition about the triggered session.

17. The method of claim 13, wherein the condition includes a start time of the triggered session, the number of location measurements, and a location measuring period.

18. The method of claim 17, wherein the determining step includes:

analyzing 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

checking whether a present time corresponds to the stop time.

19. The method of claim 13, wherein the condition includes a start time and an end time of the triggered session.

20. The method of claim 13, wherein the triggered session end message comprises at least one of a session-id parameter and a status code parameter.
