Abstract: Call control methods are disclosed for a multi-zone, packet-based communication system using certain host devices, termed reservation proxy elements, or RPEs to establish reservations of bandwidth for calls on behalf of other participating hosts. RPEs (132-138) receive and join a multicast group address to be used for a call, and exchange RSVP signaling messages across one or more inter-zone, packet network links (148, 150, 152, 154) to reserve communication resources for the call on behalf of participating devices in various zones. The RPEs receive the multicast group address from zone controller(s) (124-130) having received a call request for a talkgroup call. The zone controllers identify the multicast group address for the call and determine locations of participating devices and RPEs for the call. Upon the RPEs reserving communication resources for the call and communicating the reservation to the zone controller(s), the zone controller(s) grant the call and participating devices join the multicast group to participate in the call. The multicast group address used for the RSVP reservation is the same address used for the actual call.

Abstract: A Packet Network for use in association with a wireless communication system employs packet distribution and call set-up methods optimized to select from a plurality of network routing devices, a single node (i.e., Rendezvous Point (VP) or.multicast core) as a function of attributes exhibited by the communication devices involved in the call or as a function of various communication system performance and/or quality of service (QOS) attributes, including but not limited to, bandwidth requirements, resource availability, network processing capacity, network response time, network traffic data, information technology and other knowledge and know-how regarding system equipment, system software, system integration, installation and/or deployment, bit error rate (BER), received signal strength indication (RSSI), quality of service (QOS) metrics, and any other measure of system performance or call quality.
