摘要： The present disclosure provides an efficient and effective method for allocating provisional PUIDs and PGIDs to subscriber units and groups during a failure, such that when the communication system recovers, there is a decrease in or elimination of the number of dropped or missed communications. The present disclosure reserves a range of provisional PUIDs and PGIDs for resource controllers operating in a region of system failure to assign when subscriber units roam into the region of failure in the communication system. The present disclosure addresses creating PUID and PGID ranges for resource controllers to assign to roaming subscriber units in order to allow for assignment of PUIDs and PGIDs during periods of subsystem isolation and site trunking, i.e., when the particular site or subsystem cannot communicate with the rest of the communication system. The present disclosure also addresses recovering from these situations, re-registration, and reallocation of PUIDs and PGIDs.

摘要： Methods are disclosed for determining a link Op from among a plurality of host devices on a LAN, for exchanging control messages between a communication server and one or more sites having a link Op and a listening Op and for the link Op and/or listening Op to detect and recover from missing packets in a sequence of IP packets received from the server. The link Op and listening Op join a control multicast group address to receive control messages from the server. The link Op establishes a reliable message transfer session with the server. Upon the link Op detecting a missing packet, the link Op may request that the communication server resend the packet. Upon the listening Op detecting a missing packet, the listening Op determines whether the link Op will request retransmission of the missing packet. If the link Op is determined to not request retransmission of the missing packet, the listening Op requests retransmission of the missing packet or accepts the packet as missing and processes an out-of-sequence packet. If the link Op is determined to request retransmission of the missing packet, the listening Op discards the packet and relies upon the link Op to request retransmission of the missing packet.

摘要： A method of call control in a packet-based communication system having consoles, distributed among one or more console sites, that are adapted to monitor talkgroup calls. The console sites are served by console site links having a limited available bandwidth. Upon receiving a request for a talkgroup call, there is identified a number of priority consoles requesting participation in a talkgroup call. For example, the priority consoles (or console operators) may indicate that monitoring of the talkgroup call is “critical” for those consoles. Based on the location of the priority consoles, a number of priority console sites are identified for the talkgroup call. If sufficient bandwidth (e.g., call units of bandwidth) is available (or made available) to each of the priority console sites, the call is granted. Alternatively or additionally, the call may be granted to certain non-priority console sites if bandwidth is available. Bandwidth may be made available for critical talkgroups at certain sites by pre-empting non-critical talkgroups being monitored at those sites.

摘要： A system and method for monitoring congestion in a communication system including an external packet switched network. The communication system includes a plurality of interconnected host devices, such as base stations, consoles, zone controllers. To determine the presence of congestion on links between a pair of host devices, a series of sequential packets are transmitted between the pair. The sequentially transmitted packets are then monitor fluctuations in transmission delays and lost packets. These two criteria are used to identify congestion levels present on the various links in the communication system, and communications on the relevant interzone link are controlled based on the identified congestion level.
