Abstract:
1. 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 and at least one demodulator LMU further comprises: determining a representative point based on geographic information for the active set and determining a geographic area associated with the representative point; and dividing the geographic area into radial segments and identifying the at least one cooperator LMU and the at least one demodulator LMU based on the radial segments.
