    Abstract: A system and method for signaling and delivering group communication data, such as push-to-talk (PTT) setup data, to a dormant wireless telecommunication device across a control channel on a wireless communication network. Each wireless telecommunication device is able to direct a single group communication stream to a designated target group of other wireless telecommunication devices, and the wireless telecommunication device has a dormant state in which the wireless telecommunication devices bridges a control channel with a communication server and an active state in which the wireless telecommunication device bridges a dedicated communication channel with the communication server. The wireless telecommunication device receives group communication setup data though a control channel for incoming group communications, and such delivery occurring without fully bridging a dedicated communication channel to that wireless telecommunication device.

    Abstract: An apparatus and method for enabling fast set up for push-to-talk (PT) communications in a wireless communication network. PTT set up related messages are identified through a specially designated header and the messages with the special designated header are transmitted through signaling channels from a radio transmission unit to a mobile device.

    Abstract: En telecomunicacion inalambrica de grupo, tal como llamadas presionar-para-hablar (PTT), una comunicacion de voz es transmitida a traves de paquetes de datos de protocolo de Internet a otros dispositivos miembro del grupo PTT; por lo menos un servidor de comunicacion (106) recibe una corriente de comunicacion sencilla desde un dispositivo inalambrico en comunicacion, tal como una llamada PTT, y crea una comunicacion de grupo a todos los dispositivos de telecomunicacion inalambrica del grupo designado con la transmision de los paquetes de datos de protocolo de Internet que contienen los datos de voz de la corriente de comunicacion a uno o mas dispositivos de telecomunicacion inalambrica del grupo de recepcion que puede recibir y manejar t paquetes; otra infraestructura de red inalambrica se puede utilizar para ayudar al servidor de comunicacion en la generacion y transmision de los paquetes de datos del protocolo de Internet a los dispositivos de telecomunicacion inalambrica de recepcion.

    Abstract: A system and method for minimizing latency for direct group communications, such as push-to-talk (PTT) calls, among a group of wireless telecommunication devices on a wireless telecommunication network. The wireless telecommunication device selectively requests and then receives an open dedicated broadcast channel for an outgoing communication, which can include a group communication stream to a communication server that receives and creates a group communication to all wireless telecommunication devices of the designated group. The wireless telecommunication device selectively receives a broadcast channel based upon a predetermined probability, and assigns a greater probability of receiving an open broadcast channel for requests to transmit group communication streams than for requests to open a broadcast channel that are not for a group communication.

    Abstract: An apparatus and method for efficiently updating location information of a mobile device (102) in a wireless communication network, such as a cellular network, is disclosed. The mobile device sends its location information through a route update message to a base station controller (104). This route update message is sent over the access channel if the traffic channel is not up. When the base station controller realizes the mobile device has changed its location, the base station notifies the change to a location server (202), which sends a location update message to an application server (112).

    Abstract: Un sistema y metodo para reducir al minimo la latencia para comunicaciones de grupo directas, tal como llamadas presionar-para-hablar (PTT) , entre un grupo de dispositivos de telecomunicacion inalambrica en una red de telecomunicacion inalambrica; el dispositivo de telecomunicacion inalambrica solicita de manera selectiva y despues recibe un canal de transmision dedicado abierto para una comunicacion de salida, el cual puede incluir una corriente de comunicacion de grupo directa para un servidor de comunicacion que recibe y crea una comunicacion de grupo para todos los dispositivos de telecomunicacion inalambrica del grupo designado; los dispositivos de telecomunicacion inalambrica reciben, de manera selectiva, un canal de transmision con base en una probabilidad predeterminada, y asignan una mayor probabilidad de recibir un canal de transmision abierto para que las solicitudes transmitan corrientes de comunicacion de grupo directas en lugar de solicitudes abiertas a un canal de transmision que no son para una comunicacion de grupo directa.

    Abstract: In group wireless telecommunication, such as push-to-talk (PTT) calls, a voice communication is broadcast through Internet protocol data packets to other member devices of the PTT group. At least one communication server receives a single communication stream from a communicating wireless device, such as a PTT call, and creates a group communication to all wireless telecommunication devices of the designated group with the broadcast of Internet protocol data packets containing the voice data of the communication stream to one or more wireless telecommunication devices of the receiving group that can receive and handle the packets. Other wireless network infrastructure can be used to assist the communication server in generation and broadcast of the Internet protocol data packets to the receiving wireless telecommunication devices.
