    Abstract: A method and apparatus for adding a member to an active call in a group communication network provides for receiving a member list from a user and sending a request to a server to add the member list to the active group call. The method and apparatus further provides for announcing each member in the member list that they are being added to the group call, receiving acknowledgement from a member who wishes to participate in the group call, and forwarding media to the member. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.

    Abstract: A method and apparatus for joining a user to a call in a group communication network provides for receiving an indication from a user who wishes to initiate a group call and sending a request to a server to add the user to the group call if the group call is in progress. The method and apparatus also provides for receiving a response from the server indicating that the group call is in progress, alerting the user of being added to the group call, and receiving media from the server after a traffic channel is re-established. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signalling even when mobiles are dormant and no traffic channel is active.

    Abstract: A method and apparatus for delivering media to a group of target communication devices provides for multicasting media to the group of target communication devices to save network resources. The disclosed embodiments provide for a significant reduction in network traffic and media processing time by transmitting media in multicast transport mode, where a single copy of the media destined for a group of target recipients is transmitted to a wireless infrastructure over the multicast path. The wireless infrastructure replicates and transmits one copy of the media to each of the target recipients that are assigned to dedicated channels, but multicasts one copy of the media to the target recipients that are assigned to a shared channel.

    Abstract: Un método y aparato para entregar medios a un grupo de dispositivos comunicaciones apuntados, permite la multipropagación de medios hacia el grupo de dispositivos de comunicaciones apuntados, de manera de economizar los recursos de la red. Las formas de realización reveladas permiten una importante reducción en el tráfico de la red y del tiempo necesario para el procesamiento de los medios, mediante la transmisión de los medios en modo de transporte de multipropagación, en lo cual una única copia de los medios destinados a un grupo de receptores apuntados es transmitida a una infraestructura inalámbrica por intermedio de la trayectoria de multipropagación. La infraestructura inalámbrica replica y transmite una copia de los medios hacia cada uno de los receptores apuntados que han sido asignados a canales dedicados, pero multipropaga una copia de los medios a los receptores apuntados que han sido asignados a un canal compartido.

    Abstract: A method and apparatus for initiating a group call in a group communication network provides for receiving a request for initiating a group call based on a member and initiating the group call based on the received member list. The method and apparatus also provides for announcing the group call to each member in the member list, receiving acknowledgement from a member who wishes to participate in the group call, and forwarding media to the member after its traffic channel is re-established. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.
