TDO/GPS Hybrid Wireless Location System

摘要

A method and system for enhancing the accuracy and robustness of locations determined for a mobile wireless transceiver (MS) in a cellular telephone communications system integrates location-related information both from an assisted GPS device embedded in the mobile unit and from infrastructure-based facilities that extract signal characteristic data at networked base stations (105). Available supporting collateral information may be additionally evaluated in the location determination to provide location estimates of enhanced robustness and accuracy.
