Abstract
In a wide area communication system that includes a central controller, a plurality of sites, and a plurality of subscriber units, a requesting subscriber unit can locate a neighboring subscriber unit in the following manner. Each of the plurality of subscriber units registers with the central controller. The central controller stores registration information in a database. When the requesting subscriber unit transmits a request for a subscriber identification of a neighboring subscriber unit, the central controller determines whether the neighboring subscriber unit exists. When the neighboring subscriber unit exists, the central controller transmits the subscriber identification of the neighboring subscriber unit to the requesting subscriber unit.
