ABSTRACT:
When a group communication group call is initiated in a multi-site communication system, the communication processing information for that particular communication group call must be established. The communication processing information is formatted by a central controller which in turn transfers that information to a destination data base of a processing multiplexer switch. The information is then stored in the destination data base such that the particular communication group call may be quickly processed. When the communication unit that initiated the call ceases to transmit and another communication unit begins to transmit, the communication processing information is updated to reflect the change in the transmitting communication unit. This continues to happen until the particular communication group call has ended; once it has ended, the communication processing information is deleted from the destination data base.
