In a wide area multizone trunked radio system with a distributed Group HLR (Home Location Register) there exists the potential for inefficient usage of the interzone audio channels. With a distributed Group HLR architecture the talkgroup to controlling zone mapping is currently configured statically via the system manager application. Once the talkgroup to controlling zone mappings are entered into the system manager they are distributed to the Group HLRs within each zone for use in multizone call processing. A talkgroup call is controlled by the zone controller of the zone which is designated as the controlling zone by the system manager application.
