Abstract: A method according to one embodiment includes: transmitting, by a mobile terminal, a secure user plane location (SUPL) position initiation message to a home-SUPL location platform (H-SLP); receiving, by the mobile terminal, a SUPL end message from the H-SLP, the SUPL end message including a parameter indicating that the mobile terminal is outside of a coverage of a visited-SUPL location platform (V-SLP); transmitting, by the mobile terminal, a SUPL triggered start message to the H-SLP, the SUPL triggered start message including a cause for re-sending the SUPL triggered start message; and receiving, by the mobile terminal, a SUPL triggered response message from the H-SLP, the SUPL triggered response message including at least one trigger parameter.

Abstract: Disclosed is a location information system based upon a SUPL (Secure User Plane Location) architecture, and more particularly, to a location positioning method and terminal based on an area event in handover between networks. The method according to one embodiment includes: if a network is changed or if a terminal is outside of the coverage area of a serving network while an area event is ongoing, requesting, by the terminal, new event trigger parameters to a home network through a first message; determining, by the home network, a serving network of the terminal by using location identifier included in the first message; receiving, the home network, the location identifier of a target area for which the positioning is requested from the determined serving network; and transmitting, the home network, the new event trigger parameters including the area identifier to the terminal through a second message.
