Abstract:
1. A method of reselecting a cell in a mobile station (MS) in an idle state using Global Positioning System (GPS), the method comprising the steps of: obtaining location change information by periodically measuring GPS location information; measuring signal characteristics from each of adjacent cells; selecting a candidate cell; calculating, for each of the adjacent cells other than the candidate cell, a difference between the signal characteristics of the adjacent cell and signal characteristics of the candidate cell; determining, for each of the adjacent cells other than the candidate cell, whether the calculated difference is greater than a predetermined threshold; and if each of the calculated differences is greater than the predetermined threshold, selecting the candidate cell as a serving cell of the MS, and otherwise, performing the cell reselection based on stored Base Station System (BSS) GPS location information of adjacent cells and the location change information.
