Abstract

An example method includes: obtaining a location of a reference mobile terminal; and either: (1) sending, to a target mobile terminal, the location of the reference mobile terminal and a trigger parameter associated with a trigger event, the trigger parameter defining a moving geographical target area; and receiving an indication that the trigger event has occurred; or (2) determining a location of the moving geographical target area; determining a location of the target mobile terminal relative to the moving geographical target area; and determining whether the trigger event has occurred; where the trigger event comprises the target mobile terminal being inside the moving geographical target area, being outside the moving geographical target area, entering the moving geographical target area, and/or leaving the moving geographical target area.

either;

(1) sending, from the server to the target mobile terminal, the location of the reference mobile terminal and a trigger parameter associated with a trigger event, the trigger parameter defining a moving geographical target area that is associated with a location of the reference mobile terminal and that is configured to move in synch with the reference mobile terminal; and

receiving, at the server from the target mobile terminal, an indication that the trigger event has occurred;

or

(2) determining, at the server, a location of the moving geographical target area based on the location of the reference mobile terminal;

determining, at the server, a location of the target mobile terminal relative to the moving geographical target area based at least in part on at least one location related measurement for the target mobile terminal; and

determining, at the server, whether the trigger event has occurred based at least in part on the location of the target mobile terminal relative to the moving geographical target area;

wherein the trigger event comprises the target mobile terminal being inside the moving geographical target area, the target mobile terminal being outside the moving geographical target area, the target mobile terminal entering the moving geographical target area, the target mobile terminal leaving the moving geographical target area, or a combination thereof.

2. The method of claim 1, wherein a shape of the moving geographical target area is a circular area centered at the location of the reference mobile terminal and having a predefined radius.

3. The method of claim 1, wherein the at least one location related measurement for the target mobile terminal is obtained based on at least one signal exchanged between the target mobile terminal and the reference mobile terminal.

4. The method of claim 1, wherein the method comprises the sending the location of the reference mobile terminal and the trigger parameter to the target mobile terminal and wherein the trigger parameter includes a Secure User Plane Location (SUPL) trigger parameter.

5. The method of claim 1, wherein the method comprises the determining, at the server, the location of the target mobile terminal relative to the moving geographical target area, the method further comprising:

exchanging Secure User Plane Location (SUPL) messages to obtain the at least one location related measurement.

6. The method of claim 1, wherein the moving geographical target area comprises a complex polygon.

7. A server for supporting location services, the server comprising:

means for establishing a first communication session with a reference mobile terminal and a second communication session between the server and a target mobile terminal;

means for obtaining a location of the reference mobile terminal using the first communication session; and

either;

(1) means for sending, to the target mobile terminal, the location of the reference mobile terminal and a trigger parameter associated with a trigger event, the trigger parameter defining a moving geographical target area that is associated with a location of the reference mobile terminal and that is configured to move in synch with the reference mobile terminal; and

means for receiving, from the target mobile terminal, an indication that the trigger event has occurred;

or

(2) means for determining a location of the moving geographical target area based on the location of the reference mobile terminal;

means for determining a location of the target mobile terminal relative to the moving geographical target area based at least in part on at least one location related measurement for the target mobile terminal; and

means for determining whether the trigger event has occurred based at least in part on the location of the target mobile terminal relative to the moving geographical target area;

wherein the trigger event comprises the target mobile terminal being inside the moving geographical target area, the target mobile terminal being outside the moving geographical target area, the target mobile terminal entering the moving geographical target area, the target mobile terminal leaving the moving geographical target area, or a combination thereof.

8. The server of claim 7, wherein a shape of the moving geographical target area is a circular area centered at the location of the reference mobile terminal and having a predefined radius.

9. The server of claim 7, wherein the server comprises the means for sending the location of the reference mobile terminal and the trigger parameter to the target mobile terminal and wherein the trigger parameter includes a Secure User Plane Location (SUPL) trigger parameter.

10. The server of claim 7, wherein the server comprises the means for determining the location of the target mobile terminal relative to the moving geographical target area, the server further comprising:

means for exchanging Secure User Plane Location (SUPL) messages to obtain the at least one location related measurement.

11. The server of claim 7, wherein the moving geographical target area comprises a complex polygon.

12. A server for supporting location services, the server comprising:

a processor configured to;

establish a first communication session with a reference mobile terminal and a second communication session between the server and a target mobile terminal;

obtain a location of the reference mobile terminal using the first communication session; and

either;

(1) send, to the target mobile terminal, the location of the reference mobile terminal and a trigger parameter associated with a trigger event, the trigger parameter defining a moving geographical target area that is associated with a location of the reference mobile terminal and that is configured to move in synch with the reference mobile terminal; and

receive, from the target mobile terminal, an indication that the trigger event has occurred;

or

(2) determine a location of the moving geographical target area based on the location of the reference mobile terminal;

determine a location of the target mobile terminal relative to the moving geographical target area based at least in part on at least one location related measurement for the target mobile terminal; and

determine whether the trigger event has occurred based at least in part on the location of the target mobile terminal relative to the moving geographical target area;

wherein the trigger event comprises the target mobile terminal being inside the moving geographical target area, the target mobile terminal being outside the moving geographical target area, the target mobile terminal entering the moving geographical target area, the target mobile terminal leaving the moving geographical target area, or a combination thereof.

13. The server of claim 12, wherein a shape of the moving geographical target area is a circular area centered at the location of the reference mobile terminal and having a predefined radius.
