A controller component of one embodiment of a system assigns a first number to a mobile station that upon location of the mobile station at a first location allows connection to the mobile station of a call that employs the first number. A controller component of the system assigns a second number to the mobile station that upon location of the mobile station at a second location allows connection to the mobile station of a call that employs the second number. The second number differs from the first number. The second location differs from the first location. In another embodiment, a controller component of a system assigns to a mobile station a number that upon location of the mobile station at any one or more of a temporary user zone and a base user zone allows connection to the mobile station of a call that employs the number. A controller component of the system selects the number to comprise fewer than seven digits.

Method of selecting a calling number for a mobile station from multiple calling numbers

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.
