Location reporting with secure user plane location (SUPL)
First Claim
1. A method of supporting location services, comprising:
- receiving, at a terminal, at least one Secure User Plane Location (SUPL) trigger parameter associated with a trigger event, the trigger event being related to a velocity or acceleration of the terminal changing by a predetermined threshold;
obtaining at least one location related measurement for the terminal;
determining, at the terminal, whether the trigger event has occurred when a change in the velocity or the acceleration of the terminal exceeds the predetermined threshold; and
transmitting, by the terminal, the at least one location related measurement when the trigger event has occurred.

Abstract
Techniques for supporting periodic and other location services with Secure User Plane Location (SUPL) and other location architectures are described. The techniques can provide position estimates for a SUPL enabled terminal (SET) to a SUPL agent periodically and/or based on trigger events. A Home SUPL Location Platform (H-SLP) receives from the SUPL agent a request for position estimates for the SET. The H-SLP starts a SUPL location session with the SET. For each of at least one reporting event during the location session, the H-SLP obtains a position estimate for the SET and sends the position estimate to the SUPL agent. The position estimate may be derived by the SET and sent to the H-SLP. Alternatively, the position estimate may be derived by the H-SLP based on measurements from the SET.
