摘要： A method and system for optimal radio channel management in a distributed connection and transport network. The method includes the steps of determining the quality of service required by a communication session, determining whether transport resources are available for immediate use by the communication session, and queuing the communication session for assignment to transport resources in accordance with the quality of service required and the availability of transport resources for immediate use. The system includes a set of assignable transport resources, an interface for requesting a communication session, a detection processor in communication with the interface for determining the quality of service required by the session, a resource processor in communication with the detection processor determining whether transport resources are available for immediate use by the session, and a queuing processor in communication with the resource processor holding the communication session for prioritized allocation to the transport resources.

摘要： A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203-208 that are in wireless communication with a plurality of subscriber units 210-217 logically arranged into a plurality of talk groups having corresponding talk group identifications. In one embodiment, each site maintains mappings 220-225 of at least one multicast address to at least one talk group identification. In another embodiment, individual subscriber units maintain such mappings 320. When a subscriber unit affiliates with a given site and talk group (501, 601), the site identifies a multicast address corresponding to the talk group. Based on the multicast address, the site can participate in traffic targeted for the multicast address and, consequently, for the talk group. In this manner, mobility Processing is decentralized, system calability is improved and call setup delays are minimized.
