Claim One:
1. Method for locating a mobile station in a digital telecommunication network, comprising the step of: measuring no-location reference data indicative of signal strength and timing advance signals from plural base stations, wherein the measuring is performed at a reference mobile station on relevant traffic routes at known positions of the mobile station, training an adaptive neural network using the measured non-location reference data as inputs and the known positions of the reference mobile station as desired outputs, measuring at a subscriber mobile station non-location data indicative of signal strength and timing advance signals from said plural base stations, wherein the measured non-location data are transmitted from the subscriber mobile station to at least one of said plural base stations, and determining a location of the subscriber mobile station using the trained adaptive neural network, wherein the trained neural network is coupled to the plural base stations and determines the location of the subscriber mobile station using the measured non-location data from the subscriber mobile station.
