Method to expand an audience in a communication system network

摘要

A central controller of a communication system network may more efficiently expand an audience of a communication in the following manner. When a communication unit of a first communication group within a first communication system transmits a request for service, the central controller determines whether the audience of that predetermined communication is to be expanded. When the audience of the predetermined communication is to be expanded, the central controller combines at least part of at least one other communication group with the first communication group based upon a predetermined grouping arrangement. Having combined the groups, the central controller processes the predetermined communication among the communication units in the first communication group and the communication units in the at least part of the least one other communication group.
