Abstract

Disclosed is a triggered session performance in a SUPL-based triggered location service, in particular, a triggered location service capable of pausing an ongoing session and then resuming the paused session by using a dedicated or common message and other certain parameters indicating a session pause/resume.

Claims

1. A method for performing a triggered session in a triggered location service in a method for performing a triggered session between a server and a terminal for a SUPL-based triggered location service, comprising:

(A) pausing, by the terminal, an ongoing triggered session; and

(B) resuming, by the terminal, the paused triggered session.

2. The method of claim 1, wherein the step (A) comprises pausing, by the terminal, the triggered session;

and sending, by the terminal, a triggered session pause message to the server, and wherein the step (B) comprises resuming, by the terminal, the paused triggered session; and

sending, by the terminal, a triggered session resume message to the server.

3. The method of claim 2, Wherein the pause message and the resume message are implemented as a dedicated SUPL TRIGGERED message or a common SUPL TRIGGERED message.

4. The method of claim 2, wherein the pause message and the resume message include a session-id parameter.

5. The method of claim 2, wherein the pause message and the resume message are the same SUPL dedicated message.

6. The method of claim 5, wherein the pause message and the resume message are implemented as a SUPL TRIGGERED PAUSE message serving as the same dedicated message, and the SUPL TRIGGERED PAUSE message includes a request-mode parameter.

7. The method of claim 6, wherein the pause message and the resume message are distinguished by a value of the request-mode parameter.

8. The method of claim 7, wherein the request-mode parameter is set to a value indicating a pause of the trigger session or a value indicating a resumption of the triggered session.

9. The method of claim 2, wherein the pause message and the resume message are the same SUPL common message.

10. The method of claim 9, wherein the pause message and the resume message are implemented as a SUPL TRIGGERED STOP message serving as the same common message, and the SUPL TRIGGERED STOP message includes a request-mode parameter.

11. The method of claim 10, wherein the request-mode parameter includes one of a value indicating a pause of the triggered session, a value indicating a resumption of the triggered session, and a value indicating a stop of the triggered session.

12. The method of claim 1, wherein the step (A) comprises sending, by the terminal, a triggered session pause request message to the server;

pausing, by the server, the triggered session in response to the pause request message; and

receiving, by the terminal, a response message notifying the pause of the triggered session from the server.

13. The method of claim 1, wherein the step (B) comprises sending, by the terminal, a resume request message of the paused triggered session to the server;

performing, by the server, the triggered session in response to the resume request message; and

receiving, by the terminal, a response message notifying the performance of the triggered session from the server.

14. The method of claim 12 or 13, wherein the response message indicating the pause of the triggered session and the response message indicating the performance of the triggered session are implemented as a SUPL TRIGGERED PAUSE RESPONSE message as the same dedicated message.

20. The method of claim 13, wherein the response message indicating the pause of the triggered session and the response message

indicating the performance of the triggered session are implemented as a SUPL TRIGGERED PAUSE RESPONSE message as the same dedicated message.

15. A terminal, comprising:

a transmitter configured to transmit a triggered session pause message or a triggered session resume message; and

a SUPL agent configured to generate the message and have a parameter included in the generated message to notify a pause of the triggered session or a resumption of the paused session.

16. The terminal of claim 15, further comprising:

a receiver configured to receive a message notifying a pause or resumption of an ongoing triggered session.

17. The terminal of claim 15, wherein the SUPL agent is configured to pause an ongoing triggered session, generate a message notifying that the session has been paused, and transmit the generated message through the transmitter.

18. The terminal of claim 15, wherein the SUPL agent is configured to resume the currently paused triggered session, generate a message notifying the resumption of the session, and transmit the generated message through the transmitter.

19. The terminal of claim 15, wherein the SUPL agent is configured to receive a message indicating a pause or resumption of the triggered session, analyze the message, and determine whether or not the ongoing triggered session has been paused or resumed.
