Abstract

A group radio communication system (20) includes a group controller (24) which communicates through a satellite-based packet switched data communication network (22) to converters (28). The converters (28) are located within radio coverage areas (36) of various radio sub-networks (26). Each radio sub-network (26) includes a base station (32), controller (30) and any number of subscriber radios. The controllers (30) manage point-to-multipoint communications between subscriber radios (34) within their radio sub-networks (26), and the group controller (24) manages point-to-multipoint communications between radio sub-networks (26). The converters (28) translate between protocols (38, 38') established for communications within specific radio sub-networks (26) and a protocol (56) established for communication over the packet switched data communication network (22). The group controller (24) duplicates and distributes packets (118) originating in one radio sub-network (26) to other radio sub-networks (26).
