Location reporting with secure user plane location (SUPL)
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.
