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.

   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.
