Abstract

A wide area communication system is com- posed of multiple zones which are interconnected to form one very large system. Each of these zones is then composed of multiple communication sites, which arc interconnected via the zones, thus allowing communication between any site in the system. Each of the zones in the system has a unique identi- fication (zone ID) which is broadcast on the control channel of each communication site within the zone. Subscriber units (SU) active on the system need a mechanism to freely roam to any site in any zone in the system without having to have prepro- grammed knowledge of all of the zone IDS in the system.
