Abstract
A mobile telecommunications system includes within a serving system database entries that associate the identifier of a mobile unit, which could be a cellular telephone or a personal communications service (PCS) device, with a plurality of directory numbers. The mobile unit identifier may be a mobile identification number (MIN) or international mobile service identifier (IMSI), for example. The system may store this association within a home location register (HLR), within a mobile switching center (MSC), or in both. In the process of terminating a telephone call the system employs supplemental information to determine which of the plurality of directory numbers associated with the mobile unit's mobile identifier is to be employed for the purposes of the telephone call being terminated. The supplemental information may be the current location of the mobile unit, for example.
