<p>Techniques for supporting triggered location services are described. In one design, at least one location related measurement for a terminal may be obtained and used to detect for a trigger event. For an equidistance triggered service, a trigger event may be declared if the distance traveled by the terminal exceeds a predefined distance. For a relative terminal to terminal triggered service, a trigger event may be declared if the terminal is inside or outside, or enters, or leaves a moving geographical target area defined by a reference terminal. For a velocity triggered service, a trigger event may be declared if the maximum velocity of the terminal exceeds a predefined velocity. For a time-distance-velocity combination triggered service, a trigger event may be declared based on distance traveled by the terminal, velocity of the terminal, and time since the last report. For all services, a report may be sent if a trigger event has occurred. 140 130 2 0110 SUPL H-SLP 200 Target Agent SET A Location Request, (equidistance trigger) B Session Establishment Monitor location C of target SET D Update distance traveled by SET E Check for trigger event IF Trigger Response Report Trigger Event { GT TrgeTRsos H Monitor location, update distance traveled, and report any trigger event Session Termination</p> |
