METHOD AND APPARATUS FOR MOBILE POSITIONING

摘要

A method and system for determining a position of a UE includes a first network node receiving a request for positioning information about the UE. The first network node requests a first positioning procedure at a first location node. The first location node determines using the first positioning procedure that involvement by a second location node is needed. The first location node initiates a trigger for positioning information about the UE to be sent to the second location node. The second location node, upon receiving the trigger for positioning information and determining the presence of an environment measurement parameter, determines the position information of the UE by performing a second positioning procedure based on the environment measurement parameter, and sends a position calculation response with the positioning information.

1. A method for determining a position of a UE comprising the steps of:
a first network node receiving a request for positioning information about the UE; the first network node requesting a first positioning procedure at a first location node; the first location node determining using the first positioning procedure that involvement by a second location node is needed; the first location node initiating a trigger for positioning information about the UE to be sent to the second location node; the second location node, upon receiving the trigger for positioning information and determining the presence of an environment measurement parameter in said request, determining the position information of the UE by performing a second positioning procedure based on the environment measurement parameter, and sending a position calculation response with the positioning information.
