Abstract

An extended triggered location method and device is provided. The device includes the following: a location calculating unit to calculate location of the target terminal and determine the location information, and a third party location reporting unit to send the location information of the target terminal to the third party terminal periodically or only when the area triggered condition is sufficed. With the present invention, the third party terminal can obtain the location information of the target terminal periodically or receive the notice of the target terminal'"'"'s entry into/exit from a target area, in accordance with the principles of periodical location or area trigger location. Thereby, the invention supplies new location service application and satisfies the subscriber'"'"'s demand for different location service applications.

7. The triggered location device according to claim 6, wherein, the location policy negotiating unit is configured to make a setting to instruct the location notifying unit to notify the third party SET of the location information of the target SET, if the third party is specified in a triggered location start message sent from the target SET to a location server or in a mobile location protocol triggering location report request message.

8. The triggered location device according to claim 6, wherein, the location notifying unit is configured to send the location information of the target SET that carries target SET ID, location information of the target SET, and/or location information of the target SET where the target SET meets the area event triggering condition to the third party SET periodically or only when the area event triggering condition is met.

9. The triggered location device according to claim 6, wherein, the location notifying unit is further configured to send the location information of the target SET to the third party SET via the home location server for the third party SET periodically or only when the area event triggering condition is met.

10. A triggered location method, comprising:

sending, by a location server the location information periodically or when the area event triggering condition is met, according to the pre-specifying information of the third party SET, after the location information of the target SET is obtained in a location stage.

11. The triggered location method according to claim 10, further comprising:

pre-specifying information of a third party SET that requires location notification.

12. The triggered location method according to claim 11, wherein, the pre-specifying information of a third party SET that requires location notification comprises:

for SET-initiated triggered location, specifying the third party SET in a trigged location start message sent from the target SET to the location server or specifying the third party SET in private setting of the target SET; and

for network-initiated triggered location, specifying the third party SET in a Mobile Location Protocol Triggering Location Report Request, MLP TLRR, message sent from a Security User Plane Location, SUPL, agent to the location server, and making, by the location server, the setting to instruct notifying the third party SET of the location information via a triggered location start message that carries the information in the MLP TLRR message.

13. The triggered location method according to claim 12, wherein, the private setting of the target SET comprises:

whether notification and verification are both required for a location requester and/or the third party SET to be notified of the location; and

/or

whether to notify and verify once in initial stage of a triggered location procedure or whenever a location session starts; and

/or

whether to notify the target SET of the location result that is sent to the third party.

14. The triggered location method according to claim 13, further comprising:

for network-initiated periodical location or area event triggered location, sending a message carrying parameters of notification and/or verification to the target SET, in the initial stage of location or whenever the location starts, if the private setting of the target SET specifies verification from the target SET is required for the requester and/or the third party SET;

receiving a SUPL triggered start message, in which the parameters indicating whether to permit the notification and/or verification is carried, from the target SET;

sending a SUPL triggered response message to the target SET, if the target SET permits the notification and/or verification;

not sending the location information or the triggered event to the third party when the location procedure is terminated or the area event is triggered, if the target SET verifies to reject the request for sending the location information to the third party.

15. The triggered location method according to claim 10, wherein, the process of sending the location information to the third party SET further comprises:
