Method for reducing use of interzone audio resources in a multizone communication system

摘要

A radio communication system includes a plurality of sites that each belong to one of a plurality of zones. The plurality of zones are each linked to a zone controller and the plurality of sites are employed to facilitate communications among a plurality of communication units affiliated therewith. A method of establishing a communication between two of the plurality of communication units that are presently affiliated with sites not belonging to a common zone includes the step of determining a preferred zone for at least one of the plurality of communication units. After identifying a usable site that belongs to the preferred zone, the communication unit then affiliates with the usable site to facilitate the communications with the second communication unit.
