摘要： A system for channel assignment in a trunked transmission communication system including a plurality of subscribers. A plurality of subscribers is provided home channel assignment to reduce collisions. A home channel alias is provided for home channel coverage where a designated home channel is unavailable. A system for call grouping is provided to avoid talk group splitting. A first check is used to determine if other channels are conducting communications with identical home and talk group information. A second check is available after a temporary channel assignment. In one system both the home channel aliasing and call grouping are performed.

摘要： An Internet protocol (IP) packet switching communication system using real time transport protocol (RTP). Control packets map group identification codes to a multicast address on a network. Control packets are distributed on the network using simple object access protocol (SOAP) messages with extensible markup language (XML) payloads. Mapping may include dynamic or static functions. Multicast address data is distributed among routers. A message from a caller is multicast by the routers, based on the multicast address, to one or more destinations.
