SYSTEM AND METHOD FOR LOCATING A MOBILE TERMINAL USING SECURE USER PLANE LOCATION

摘要

A method and a server for determining a location of a targeted mobile set using Secure User Plane Location (SUPL) in a wireless communications network are provided. The method includes receiving a request message requesting location information of the targeted mobile set, from a SUPL agent; sending a location initiation message (SUPL INIT) to the targeted mobile set in response to the received request message from the SUPL agent; determining a positioning method for the location service of the targeted mobile set after receiving a location capability from the targeted mobile set; and performing each of a plurality of positioning procedures by using the determined positioning method until a timer related to the determined positioning method is due or the target mobile set obtains a new positioning method, wherein the plurality of the positioning procedures are performed when an event of the targeted mobile set occurs or when triggered periodically.

1. A system for determining a location using SUPL (Secure User Plane Location), comprising:
a home location server for transmitting a location initiation message (SUPL INIT) to a targeted mobile set in response to a request message from a SUPL agent for requesting a location service of the target mobile set; and a targeted mobile set for reporting an event occurrence to the home location server whenever an event occurs, after a positioning method is determined by using a location capability transmitted to the home location server in response to the received SUPL INIT, wherein the home location server or the targeted mobile set performs each of a plurality of positioning procedures according to the determined positioning method during a time set by the SUPL agent until a timer related to the determined positioning method is due or the target mobile set obtains a new positioning method, and wherein each of the plurality of positioning procedures is performed when the event of the targeted mobile set occurs or when triggered periodically.
