Disclosed is a location information system based upon a SUPL(Secure User Plane Location) architecture, and more particularly, to a location positioning method based on an area event in handover between networks. The method comprises: 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.
