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.

Abstract: 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.

Abstract: Un método de distribución de paquetes para uso en un sistema de comunicaciones (200) que tiene una pluralidad de dispositivos de comunicaciones (348 - 656) distribuidos entre una o más zonas de comunicación, estando las zonas de comunicación interconectadas lógicamente por uno o más dispositivos de red (114), que comprende las etapas de: recibir una petición de llamada desde un dispositivo de comunicaciones fuente para la distribución de paquetes de múltiples destinos, usando un nodo central de múltiples destinos, a uno o más dispositivos objetivo; y seleccionar uno de los dispositivos de encaminamiento de la red (108, 110, 114) como el nodo central de múltiples destinos; caracterizado por que el método comprende además: seleccionar un nodo central de múltiples destinos como una función de la localización del dispositivo fuente u objetivo; asignar un intervalo de direcciones de grupo de múltiples destinos al nodo central de múltiples destinos; seleccionar desde el intervalo direcciones de grupo de múltiples destinos asociado con el nodo central de múltiples destinos, al menos una dirección de grupo de múltiples destinos a utilizar para distribuir paquetes a uno o más de los dispositivos de comunicación objetivos; y distribuir la, al menos una, dirección de grupo seleccionada de múltiples destinos a uno o más dispositivos de comunicaciones objetivo, en el que una vez recibida la, al menos una, dirección de grupo de múltiples destinos los dispositivos de comunicaciones objetivos señalizan su intención de juntar la dirección de grupo de múltiples destinos enviando un mensaje juntar de múltiples destinos.

Abstract: 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. 8 ). Zone controllers (830, 832) separately identify control multicast group addresses and send them to affiliating devices in their respective zones. A controlling zone controller (830) dynamically identifies a payload multicast group address that is used by participating devices in both zones. The participating sites (806, 816) issue Join commands to associated network devices (810, 822) to receive payload messages addressed to the payload multicast group address and control messages addressed to their control multicast group address.
