FIELD: radio engineering, communication.
SUBSTANCE: network-initiation of area-based positioning of a roaming terminal is discriminated according to a proxy mode and a non-proxy mode, and area-based positioning for the roaming terminal is performed through various methods according to whether the secure user plane (SUPL) location platform (SLP) for performing the positioning procedure with respect to the allocated mode, the visited SLP (V-SLP) or the home SLP (H-SLP).
EFFECT: method for network-initiated area event triggered positioning for a roaming terminal based on a network positioning system which supports secure user plane location, which provides efficient location of a roaming terminal.
