Abstract
The present invention addresses the need for providing dispatch service to dispatch clients via a packet-switched network, such as the Internet, by disclosing a network dispatch manager, a dispatch gateway, a method for a network dispatch manager to provide dispatch service, and a method for a dispatch gateway to provide dispatch service. Dispatch service is provided via a multicast capable, packet-switched network (,) connecting a network dispatch manager (,) to dispatch gateways (,) and a packet-switched network (,), such as the Internet, connecting the dispatch gateways to dispatch clients (,). The network dispatch manager (,) assigns a multicast group to each dispatch gateway and uses the multicast group to multicast voice packets to the dispatch gateways (,). The dispatch gateways (,), in turn, perform any required packet duplication needed to forward the voice packets, via the packet-switched network (,), to the dispatch clients involved in the dispatch call. Thus, dispatch service can be provided to dispatch clients in addition to wireless devices.
