Abstract
The present invention encompasses a method of facilitating a talkgroup call throughout a communication network (100). A typical multi-system network (100) includes a plurality of communication units (122), a plurality of communication location areas (117-119), and a plurality of system controllers (110, 116). A communication unit (122) sends a request for a talkgroup call involving members of a first talkgroup to a system controller (116). The system controller (116), after receiving the talkgroup call request, determines which other communication systems in the multi-system network (100) contain members of the requested talkgroup. The system controller (116) sends a talkgroup call command to all communication systems that presently contain members of the first talkgroup, thereby facilitating the talkgroup call throughout the communications network.
