Patent ID: 8150421

Claim:
A system for locating a mobile wireless device configured to communicate with a wireless communications system via a control plane and a user plane, wherein the user plane comprises a data channel, comprising: a wireless location system (WLS) comprising a plurality of location measuring units (LMUs) configured to be tasked to receive uplink transmissions from the wireless device and to employ algorithms to locate said wireless device using data derived from received uplink transmissions, wherein said WLS is overlaid on said wireless communications system; a server configured to communicate with said WLS and to communicate via a user plane data channel with a wireless device to be located, and to obtain from said wireless device, via said user plane data channel, information useful for tasking said WLS, wherein said user plane data channel comprises an Internet Protocol (IP) link carried by a user plane of the wireless communications system; wherein said information useful for tasking includes the following: a hop pattern being used by the wireless device; and information useful for at least partially demodulating a signal from the wireless device to extract control signaling and error coding; wherein said server is further configured to communicate said information useful for tasking to the WLS.
