Abstract (en)

[origin: WO0074326A1] 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 method for a network dispatch manager to provide dispatch service, and a method for a dispatch client to obtain dispatch service. Dispatch service is provided via a multicast capable, packet-switched network (124) connecting a network dispatch manager (101) to dispatch clients (126 and 128). A multicast group is assigned to a dispatch group and used to broadcast packets containing speech information to dispatch clients that are members of that dispatch group. Thus, dispatch service can be provided to dispatch clients in addition to wireless devices (134, 136 and 138).
