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