initiating, by the location server, a session with the target terminal when a client requests a positioning for a target terminal;

sending trigger information from the location server to the target terminal;

receiving a positioning-start message which the target terminal sends for every positioning period according to the trigger information sent; and

exchanging consecutive messages between the location server and the target terminal to calculate a position of the target terminal, and sending the calculated position value of the target terminal to the client.

2. The method of claim 1, wherein the trigger information is sent by a session trigger request message.

3. The method of claim 1, wherein the trigger information is a part of trigger parameter(s) pertaining to periodic triggers.

4. The method of claim 3, wherein the part of trigger parameter(s) includes at least a period for the periodic positioning, and starting time and ending time of the periodic positioning.

5. The method of claim 1, further comprising when the terminal performs the positioning, sending the calculated position value from the target terminal to location server using a session report message.

6. The method of claim 1, further comprising:

storing the trigger information by the terminal, and sending a session-start message to the location server; and

when receiving the session-start message, informing the client, by the location server, that the terminal has accepted the positioning request.

7. The method of claim 1, wherein the location server sends a session initiating message including at least trigger type information to the target terminal in order to start a session with the target terminal.

8. The method of claim 7, wherein the trigger type information denotes a periodic service type.

9. The method of claim 1, further comprising sending a positioning request message including trigger parameters related to the positioning for the target terminal from an agent to the location server.

10. A periodic positioning method in a mobile communications system in a positioning method of a terminal between at least one or more terminals and a location server, the periodic positioning method comprising:

receiving, in a terminal, a session initiating message including trigger type information from the location server;

starting a session with the location server according to the session initiating message;

receiving a trigger message including a trigger parameter from the location server;

sending a positioning initiating message to the location server according to the trigger parameter;

performing the positioning between the location server and the terminal; and

receiving a session-end message from the location server to end the session.

11. The method of claim 10, wherein the trigger type information denotes a periodic service type.

12. The method of claim 10, wherein the trigger parameter is a part of trigger parameters) pertaining to periodic triggers.

13. The method of claim 10, wherein the trigger parameter includes at least a period for the periodic positioning, and starting time and ending time of the periodic positioning.

14. The method of claim 10, further comprising sending a positioning request message from an agent to the location server, the positioning request message including a trigger parameter related to the positioning for the target terminal.

15. The method of claim 10, further comprising sending the positioning result from the location server to the agent when the positioning is ended.

16. The method of claim 10, wherein the session-end message is transferred from the location server to the terminal after the last position result has been reported to the agent.

17. A periodic positioning method in a mobile communications system in positioning method of a terminal between at least one or more terminals and a location server, the periodic positioning method comprising:

receiving a session-start message from a terminal;

sending a session response message from the location server to the terminal;

receiving a positioning initiating message sent by the terminal based upon a periodic trigger condition;

performing positioning between the terminal and the location server; and

sending the positioning result from the location server to the terminal.

18. The method of claim 17, wherein the session response message includes at least a session ID or a positioning method.

19. The method of claim 17, wherein the positioning initiating message is sent when the periodic trigger condition is satisfied.

20. The method of claim 17, wherein the session-start message includes at least a trigger event parameter.

21. The method of claim 17, wherein the trigger event parameter includes at least trigger type information or a trigger parameter.

22. The method of claim 21, wherein the trigger type information denotes a periodic service type, and the trigger parameter includes at least a period for the periodic positioning, and starting time and ending time for the periodic positioning.

23. The method of claim 17, further comprising, for a long period for the positioning, sending a session-end message from the location server to the terminal at the end of every period, and ending the positioning for one period.

24. A periodic positioning method of a mobile communications system in a positioning method of a terminal between at least one or more terminals and a location server, the periodic positioning method comprising:

sending a session-start message including trigger information to the location server;

receiving a response message from the location server;

sending a positioning initiating message from the terminal to the location server according to a trigger parameter;

performing positioning between the terminal and the location server; and

receiving a report message including the positioning result from the location server.
