摘要： A large volume of high accuracy location data is determined in many commercial wireless networks from location based services (LBS) and, in the United States, for E911. Uplink-Time-Difference-of-Arrival (UTDOA) and Assisted GPS (AGPS) are the predominant geolocation technologies providing these high accuracy locations. In the US alone over 10 million wireless subscribers are located every month because they dial the national emergency number “911” on their mobile phones. This rich set of location data provides an a priori distribution of the location of subscribers in the wireless network. All digital wireless communications networks have a mechanism for the subscribers to time synchronize their handsets to the network. This mechanism provides a band of ranges from the serving cell site to the handset. An a posteriori location estimate can be determined very quickly by considering the a priori distribution of callers in the range band that the current subscriber is in.

摘要： In a wireless location system, a method for determining frame and slot timing information for use in receiving an uplink signal from a user equipment (UE) device assigned to an uplink Dedicated Physical Control Channel (DPCCH) includes receiving signals in the uplink DPCCH at a location measurement unit (LMU) of the WLS. The method also includes detecting a predefined bit pattern known to be present in a plurality of predefined slots of the uplink DPCCH. Next, the frame and slot timing information are determined for the uplink DPCCH based on the detected bit pattern. Finally, the frame and slot timing information is used for collecting uplink signals from the UE for use in location processing.

摘要： In an overlay, network-based, wireless location system, LMUs typically co-located with BTSs are used to collect radio signaling both in the forward and reverse channels for use in TDOA and/or AOA positioning methods. Information broadcast from the radio network and by global satellite navigation system constellations can be received by the LMU and used to reduce the difficulty of initial system configuration and reconfiguration due to radio network changes.

摘要： For Wireless Communications Networks (WCNs) that support soft handover, cooperator receiver selection for a TDOA, AOA, TDOA/AOA, or hybrid network-based or network-overlay Wireless Location System (WLS) must contend with one or more network base stations as a serving cell. When the active set contains more than one member, two techniques for determining a set of cooperating and demodulating receivers to use in the signal collection for location estimation is disclosed. In one embodiment, the active set members are constructively reduced to a single member that is used as a proxy serving cell. In another embodiment, the information contained in the active set membership is retained and a new set of demodulating and cooperator receivers are generated based on the entire membership of the active set.
