Claim Text:
1. A method comprising: receiving, by a server, first measurement data from wireless communication subscriber units within a wireless communication network, deriving the cell characteristic values for the first set of cells based on the first measurement data, receiving, by the server, second measurement data for a second set of cells within the wireless communication network obtained by a wireless communication subscriber unit, applying, by the server, the timing offset values to the timing data included in the second measurement data to obtain offset timing data; computing, by the server, timing difference values for pairs of cells based on the offset timing data; applying, by the server, the computed timing difference values to contour models; and determining, by the server, a geolocation of the wireless communication subscriber unit based on the computed timing difference values applied to the contour models.
