Patent ID: 8442538

Claim:
A method of identifying a set of cooperator and demodulator location measuring units (LMUs) for use in locating a mobile device in a Code Division Multiple Access (CDMA)-based wireless communications network (WCN), wherein the demodulator LMUs perform full or partial demodulation of an uplink signal from the mobile device and the cooperator LMUs receive the uplink signal from the mobile device without performing demodulation, comprising: obtaining data identifying an active set of base stations through which active communication is established between the mobile device and the WCN; based on the active set, identifying at least one cooperator LMU and at least one demodulator LMU; employing the at least one cooperator LMU and the at least one demodulator LMU to collect signal data from the mobile device; and employing the signal data to locate the mobile device; wherein said identifying at least one cooperator LMU further comprises: for each said base station, determining a geographic area associated with the base station and dividing the geographic area into radial segments; and selecting, for each of the radial segments, cooperator LMUs such that the selected cooperator LMUs are substantially equally distributed among the base stations and a range of relative azimuths about each base station.
