Abstract:
1. An apparatus for determining position information of one or more UEs (User Equipments), comprising: a plurality of UEs for requesting GPS (Global Positioning System) auxiliary information to a Node B of a specific cell where the UE is positioned; a plurality of Node Bs for requesting the GPS auxiliary information to a Radio Network Controller (RNC) in response to the GPS auxiliary information request from UEs positioned in a specific cell; a GPS (Global Positioning System) auxiliary information manager for generating and storing GPS auxiliary information associated with a specific cell using a GPS satellite signal received via a built-in GPS receiver; and an RNC (Radio Network Controller) connected to the plurality of Node Bs, for receiving GPS auxiliary information from the GPS auxiliary information manager in response to a request signal of at least one Node B from among the plurality of Node Bs, optimizing the received GPS auxiliary information for every Node B, selecting the optimized GPS auxiliary information, and periodically transmitting the selected optimized GPS auxiliary information, in which the Node Bs broadcast the optimized GPS auxiliary information received from the RNC to the UEs positioned in the specific cell over a broadcast channel.
