Abstract:
A method for determining a home-zone database using a simulation data measured as a mobile unit roams around a plurality of locations in a mobile communication system, comprising the steps of:(a) measuring a respective pilot signal strength and a PN(Pseudo Noise) offset received from a plurality of base stations within the system by a mobile diagnostic monitor that tracks its own position while measuring pilot signal strength; (b) calculating a distance between the respective base station and the respective location based on a measured signal strength of the pilot signal measured in step (a); (c) generating a graphical relationship between the measured pilot signal strength at each location and the calculated distance such that only a calculated distance above a predetermined threshold is used to define a home-zone boundary; (d) generating a plurality of bins; (e) estimating a new pilot signal strength for each bin by associating the generated graphical relationship to the plurality of the bins; and (f) searching a predetermined base station database to retrieve a cell identification information of the PN offset responsive to the estimated new pilot signal strength.
