ABSTRACT:
The present invention encompasses a method of facilitating talkgroup communications across a multiple-system 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 (100, 116). Upon migration of a communication unit (122) from one communication system to another, the communication unit (122) sends a registration request to the system controller (116) at the new communication system (102). The system controller (116) determines whether the talkgroup of the migrating communication unit (122) is registered with the new communication system (102). If the talkgroup is not registered with the new system (102), a database (120) is updated with the new talkgroup information, thereby facilitating talkgroup communication involving, members of the talkgroup.
