Abstract
A method for assigning a system location to an ISU (32) residing in a wireless communication system coverage area (20) that has a plurality of billing territories (40). Base points (42) are defined to be proximate the billing territories (40) such that each of the base points (42) provides a system location for a corresponding billing territory (40). Each of the billing territories (40) has a plurality of reference points (44) distributed therein in accordance with a geographic independent algorithm such that each of the reference points (44) is described by an offset from the corresponding base point (42) of the corresponding billing territory (40). By obtaining an actual location (54) of the ISU (32) and identifying one of the reference points (44) closest to the actual location (54), the ISU (32) is assigned the system location of the identified reference point (44). In a preferred embodiment, the method and apparatus of the present invention are used in a mobile satellite system (19).
