Location positioning method in handover between networks
First Claim
1. In a method for performing, by a terminal, a triggered positioning with a serving network through a home network in response to a positioning request of an external agent, a location positioning method in handover between networks, comprising:
- requesting, by the terminal, at least one of event trigger parameters to the home network through a first message while an area event session is ongoing;
determining, by the home network, the serving network of the terminal by using location identifier included in the first message;
receiving, by the home network, one or more area identifier information of a target area for which the positioning is requested from the determined serving network; and
transmitting, by the home network, the at least one of event trigger parameters including the area identifier information to the terminal through a second message.

Abstract
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.

16. In a method for performing, by a terminal, a triggered positioning with a network in response to a positioning request of an external agent, a location positioning method in handover between networks, comprising:
-
requesting, by the terminal, at least one of event trigger parameters to the network through a first message in case the network is changed while an area event session is ongoing;
determining, by the network, a location server of the terminal by using location identifier included in the first message;
receiving, by the network, area identifier of a target area for which the positioning is requested from the determined location server; and
transmitting, by the network, the at least one of event trigger parameters including the area identifier to the terminal through a second message. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. In a method for performing, by a terminal, a triggered positioning with a network in response to a positioning request of an external agent, a location positioning method in handover between networks, comprising:
-
requesting, by the terminal, at least one of event trigger parameters to the network through a first message if the terminal receives a message from the network informing that the terminal is outside of the coverage area of a location server while an area event session is ongoing;
determining, by the network, the location server of the terminal by using location identifier included in the first message;
receiving, by the network, area identifier of a target area for which the positioning is requested from the determined location server; and
transmitting, by the network, the at least one of event trigger parameters including the area identifier to the terminal through a second message. - View Dependent Claims (24, 25, 26, 27, 28, 29)

30. In a method for performing, by a terminal, a triggered positioning with a first and a second serving networks through a home network in response to a positioning request of an external agent, a location positioning method in handover between networks, comprising:
-
starting, by the terminal, a positioning procedure with the first serving network while an area event session is ongoing;
if the first serving network informs that the network is changed, requesting at least one of event trigger parameters to the home network through a first message;
ending, by the home network, a session with the first serving network, and determining the second serving network by using location identifier included in the first message;
forwarding the request for the trigger parameters of the terminal to the determined second serving network;
receiving one or more area identifier information of a target area for which the positioning is requested from the determined second serving network; and
transmitting, by the home network, the at least one of event trigger parameters including the area identifier information to the terminal through a second message. - View Dependent Claims (31, 32, 33, 34, 35)
