First Claim
Patent Images
1. A network-initiated area event triggered positioning method for a roaming terminal in a mobile communication system, comprising:
- sending by a first server, a session initiation message for initiating a trigger session to the roaming terminal;
receiving, by the first server, a session start message from the roaming terminal;
requesting, by the first server, area identities (ids) related to area event-triggered positioning from a second server and obtaining, by the first server, area ids;
sending, by the first server, a session response message including at least a trigger parameter to the roaming terminal;
receiving, by the first server, a positioning initiation message from the roaming terminal and transferring it to the second server;
receiving, by the first server, a calculated position value of the roaming terminal from the second server and transferring, by the first server, the received calculated position value to the roaming terminal; and
providing, by the first server, the calculated position value received from the roaming terminal, to an agent, wherein the calculated position value is received from the roaming terminal when the trigger parameter is satisfied by the roaming terminal.

Abstract
A network-initiated area event triggered positioning method for a roaming terminal in a session-based position information system is disclosed. 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 in various manners according to whether an SLP for performing the positioning procedure with respect to the discriminated modes is a V-SLP or an H-SLP.
