Abstract
A Universal Mobile Telecommunications System (“UMTS”) is modified to provide location-determining services similar to Wireless-Assisted-GPS (“WAG”) services to mobiles without requiring the deployment of a GPS receiver inside the UMTS network. The resulting network is known as a UMTS Network Assisted GPS (“UNAG”) network. A UNAG network is created by deploying a UNAG server inside a UMTS network. The UNAG server provides WAG-like services to mobiles. Only one UNAG server is needed in an entire system, allowing the cost of the UNAG server to be amortized over a number of Mobile Switching Centers (“MSCs”) in the UMTS network. The UNAG server provides excellent location-prediction accuracy and reduces the amount of time required to determine the location of a mobile in a UMTS network.
