ABSTRACT:
A distance based method for mobile station registration in a cellular communication system. The mobile station registers whenever it moves into a new cell that is greater than some predefined distance from the previous cell where it registered. Cell base stations transmit corresponding base station location information and a distance value. The mobile station receives the base station location information and computes the distance from a cell in which the mobile station last registered to the current cell in which the mobile station is present. When the computed distance is greater than the distance value associated with the registration cell the mobile station registers. Pages for the mobile station are transmitted within a group of cells within a distance of the registration cell corresponding to the registration cell transmitted distance value.
