Method of facilitating tallgroup calls in a peer communication network
First Claim
1. In a communications network that includes a plurality of peer-to-peer communication system networks, wherein each system network includes a system controller and a plurality of location areas, a method of facilitating a talkgroup call throughout the communications network, the method comprising the steps of:
- at a first communication unit of a plurality of communication units that are members of at least a first talkgroup, sending a request for a call involving members of the first talkgroup to a first system controller via a local resource controller within a location area at a first communication system network;
at the first system controller,receiving the request from the first communication unit;
determining which of the plurality of communication system networks presently contain members of the first talkgroup; and
selectively sending a talkgroup call command to those communication system networks presently containing members of the first talkgroup, thereby facilitating the talkgroup call throughout the communications network.

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.

-
at a first communication unit of a plurality of communication units that are members of at least a first talkgroup, sending a request for a call involving members of the first talkgroup to a first system controller at a first communication system network; at the first system controller, receiving the request from the first communication unit; retrieving the first talkgroup record from a first database; determining whether an identifier of a second communication system network is present in the first talkgroup record; and when the second communication system network is present in the first talkgroup record, selectively sending a talkgroup call command to the second communication system network, thereby facilitating the talkgroup call throughout the communications network.
