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 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:

receiving, from a target terminal, a triggered session pause message during the triggered session for a SUPL triggered location service;

receiving, from the target terminal, a triggered session resume message while the triggered session has been paused; and

performing the triggered session between the server and the target terminal.

2. The method of claim 1, further comprising:

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

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

3. The method of claim 1, wherein the pause message and the resume message include a session-id.

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 a pause of the triggered session or a value indicating a resumption of the triggered session.

6. The method of claim 1, wherein the pause message and the resume message are implemented as a dedicated SUPL TRIGGERED message or a common SUPL TRIGGERED message.

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

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

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

10. The method of claim 1, wherein the pause message and the resume message are implemented as a SUPL TRIGGERED STOP message 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 2, wherein the pause response message and the resume response message are implemented as an SUPL TRIGGERED PAUSE RESPONSE message as the same dedicated message.

13. The method of claim 1, further comprising:

notifying, to the 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.

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

transmitting, by the target terminal, a message notifying a pause of the triggered session to the server; and

transmitting, by the target terminal, a message notifying a resumption of the paused triggered session to the server.

15. The method of claim 14, further comprising:

notifying, by the server, that the triggered session has been paused to a source terminal/apparatus when the triggered session has been paused; and

notifying, by the server, that the triggered session has been resumed to the source terminal/apparatus when the triggered session has been resumed.
