Embodiment Construction

[0032] Exemplary embodiments of the present invention will now be described in detail.

[0033] The invention is implemented in a SUPL network, but otherwise the invention can also be applied in any wireless communication system operating according to a different specification.

[0034] In the present invention, in the session-based location information system, when the server and the terminal manage location-related trigger information, information about the terminal roaming to the visited network (the terminal moves into a specific location, stays in a specific area, or moves out of a specific area) is provided. case) the region event triggers the positioning process.

[0035] When location is triggered by an area event, the home network requests the visited network for the area id set for area-based positioning, acquires the area id, and provides the acquired area id to the roaming terminal (ie, the target SET).

[0036] In area-based (area-related or area-event-triggered)...

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.

Description

technical field [0001] The present invention relates to a mobile communication system, and more specifically relates to a network-initiated area event-triggered positioning method for a roaming terminal in a session-based position information system. Background technique [0002] The mobile communication system provides a positioning service for transmitting a terminal location to a specific entity periodically or according to a user request by including a functional part for calculating a terminal location in a mobile communication network. A location service related network structure varies according to an internal network structure such as 3GPP or 3GPP2. [0003] The method of calculating the position of the terminal includes the cell ID method of transmitting the ID of the cell to which the terminal belongs, the method of measuring the time it takes for the radio wave of the terminal to reach the base station and calculating the position of the terminal using triangulati...
