Abstract

Disclosed is an SUPL-based triggered location service which provides 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 providing a Secure User Plane Location-based (SUPL-based) triggered location service, comprising:

establishing a triggered session for the SUPL-based triggered location service between a server and a target terminal;

receiving, by the server from the target terminal, a triggered session pause message during the triggered session, the triggered session pause message related to a pause of the triggered session; and

receiving, by the server from the target terminal, a triggered session resume message while the triggered session has been paused, the triggered session resume message related to a resumption of the paused triggered session,

wherein each of the triggered session pause message and the triggered session resume message includes a session-id for the triggered session, and

wherein the triggered session pause message and the triggered session resume message are implemented as a dedicated SUPL TRIGGERED message or a common SUPL TRIGGERED message.

2. The method of claim 1, further comprising:

sending, by the server to the target terminal, a triggered session pause response message in response to the triggered session pause message; and

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

3. The method of claim 2, wherein the triggered session pause response message and the triggered session resume response message are implemented as a SUPL TRIGGERED PAUSE RESPONSE message as a same dedicated message.

4. The method of claim 1, further comprising:

receiving, from a source terminal/apparatus, a SUPL triggered location service request message including a pause mode parameter; and

transferring, to the target terminal, the pause mode parameter so as to set the triggered session.

5. The method of claim 4, wherein the pause mode parameter is set to a value indicating the pause of the triggered session or a value indicating the resumption of the paused triggered session.

6. The method of claim 1, wherein the triggered session pause message and the triggered session resume message are implemented as a SUPL TRIGGERED PAUSE message as a same dedicated message, and the SUPL TRIGGERED PAUSE message includes a request mode parameter.

7. The method of claim 6, wherein the triggered session pause message and the triggered session 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 the pause of the triggered session or a value indicating the resumption of the paused triggered session.

9. The method of claim 1, wherein the triggered session pause message and the triggered session resume message are implemented as a SUPL TRIGGERED STOP message as a same common message, and the SUPL TRIGGERED STOP message includes a request mode parameter.

10. The method of claim 9, wherein the request mode parameter includes one of a value indicating the pause of the triggered session, a value indicating the resumption of the paused triggered session, and a value indicating a stop of the triggered session.

11. The method of claim 1, further comprising:

notifying, to a source terminal/apparatus, that the triggered session has been paused after receiving the triggered session pause message; and

notifying, to the source terminal/apparatus, that the triggered session has been resumed after receiving the triggered session resume message.

12. The method of claim 1, wherein the triggered session pause message indicates that the triggered session has been paused or requests the pause of the triggered session, and

the triggered session resume message indicates that the paused triggered session has been resumed or requests the resumption of the paused triggered session.

13. The method of claim 1, wherein the triggered session pause message and the triggered session resume message are implemented using at least one designated message having a request mode parameter related to the pause or resumption of the triggered session.

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

establishing a triggered session for the SUPL-based triggered location service between a server and a target terminal;

transmitting, by the target terminal to the server, a first message notifying a pause of the triggered session to the server, when the triggered session has been paused; and

transmitting, by the target terminal to the server, a second message notifying a resumption of the paused triggered session to the server, when the paused triggered session has been resumed,

wherein each of the first and second messages includes a session-id for the triggered session, and

wherein the first and second messages are implemented as a dedicated SUPL TRIGGERED message or a common SUPL TRIGGERED message.

15. The method of claim 14, wherein the first and second messages are implemented using one designated message having a request mode parameter related to the pause or resumption of the triggered session.

16. The method of claim 15, wherein the one designated message is a SUPL message having the request mode parameter.

17. The method of claim 14, wherein the first and second messages are implemented using two different designated messages.

18. The method of claim 17, wherein the two different designated messages are different SUPL messages.

19. The method of claim 14, further comprising:

prior to a start of the triggered session, receiving, by the target terminal from the server, a SUPL message including a pause mode parameter related to the pause or resumption of the triggered session.
