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： 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： 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 for providing a mobile device in a packet data network access to a channelized network is disclosed. At a gateway between the two networks, a first channelized network message that is encapsulated in a first IP data packet from the packet data network is received. The first channelized network message is retrieved and reformatted for sending over the channelized network. The gateway then receives a second channelized network message from the channelized network. An identifier of a mobile device associated with the second channelized network message is retrieved and an IP address for the identified mobile device is determined. Then, the gateway encapsulates the second channelized network message into a second IP data packet and sends the encapsulated second channelized network message to the identified mobile device in the packet data network.

摘要： Methods for implementing talkgroup calls in an IP multicast network among competing sources, including console dispatch takeover of an active call from a subscriber, subscriber unit attempted takeover of an active call from a console, and operation of communication devices in different receive modes. In the takeover or attempted takeover situation, the methods allow for a first group of participating devices (e.g., consoles) to hear both competing sources, and for a second group of participating devices (e.g., base site repeaters) to hear only the higher priority source. The methods allow for different dekeying sequences between the competing sources after the takeover or attempted takeover, as appropriate, such that participating devices will hear the remaining source. Where multiple payloads are addressed to the same multicast group address, an exclusive receive mode enables a group of communication devices (e.g., base site repeaters) having joined the address to exclusively receive a selected one of the payloads.

摘要： A system and method for transmitting call information in a communication system having sites with long link delays. Upon a call being initiated within the communication system, a zone controller determines the participating sites that are to be involved in the call and assigns an IP multicast group address for the call. The zone controller also determines whether any of the participating sites have a long link delay. If any of the participating sites do have a long link delay, the zone controller also assigns an IP unicast address for each such site. The call information is then transmitted both on the IP multicast address as well as on each assigned IP unicast address to ensure that the call is received by each participating site without the loss of call information.

摘要： Systems and methods for implementing dispatch calls using IP multicasting protocols are disclosed. The methods include utilizing a payload multicast group address for distributing payload, and utilizing a control multicast group address for distributing control messages to members of the talkgroup in a single-zone (FIG. 1). A zone controller 116 dynamically identifies payload and control multicast group addresses and sends them to participating sites 102, 104. The participating sites 102, 104 issue Join commands to associated network devices 108, 110 to receive payload and control messages addressed to the respective payload and control multicast group addresses. There is further disclosed a system and method for implementing dispatch calls for members in multiple zones (FIG. 6). Zone controllers 630, 632 separately identify control multicast group addresses and send them to affiliating devices in their respective zones. A controlling zone controller 630 dynamically identifies a payload multicast group address that is used by participating devices in both zones. The participating sites 606, 616 issue Join commands to associated network devices 610, 622 to receive payload messages addressed to the payload multicast group address and control messages addressed to their control multicast group address.

摘要： System and method for efficiently managing communication channel assignments within talkgroups having dual mode communication units capable of operating on a first communication channel type and on a second communication channel type, and single mode communication units capable of operating only on the second communication channel type. If, at a base site, each of the communication units associated with a talkgroup is a dual mode communication unit, a call for that talkgroup is assigned to be broadcast using a channel of the first communication channel type. If, at least one of the communication units associated with the talkgroup at the base site is a single mode communication unit, the call for that talkgroup is assigned to a channel of the second communication channel type. As communication units roam between sites, channel assignments are continuously updated based on the types of communication units at each base site at any one time.
