Abstract
Disclosed is a method for building a home-zone database using data measured while moving about the home-zone service area in a mobile communication system, which includes a mobile diagnostic monitor with a GPS antenna, a mobile telephone and a base station database. The method comprising the steps of: measuring the strength of a pilot signal received from each base station in the home-zone service area; deriving a line-fitting formula indicating a variation trend of the pilot strength of each PN (Pseudo Noise) offset according to the distance between the respective base station from the monitor device; generating a plurality of bins associated to the home-zone service area in the form of a grid; estimating the pilot strength of each bin by applying the line-fitting formula to the respective bin; and searching the base station database for the PN offsets corresponding to the pilot strengths estimated for the respective bins and reading the cell identification information for each searched PN offset to build a home-zone database.
