Abstract: Un método y aparato para agregar un miembro en una llamada activa en una red grupal de comunicaciones, permite recibir una lista de miembros procedente de un usuario y enviar un requerimiento a un servidor para agregar la lista de miembros a la llamada grupal activa. El método y aparato además provee anunciar a cada uno de los miembros en la lista de miembros que están siendo agregados a la llamada grupal, recibir acuse de recibo procedente de un miembro que desea participar en la llamada grupal, y hacer llegar medios de difusión al miembro. El método y aparato también provee una reducción significativa en el tiempo y latencia de despertar de la dormición real total y mediante el intercambio de senalizaciones de llamadas grupales aún cuando los móviles están en estado de dormición y no haya un canal de tráfico activo.

Abstract: A wireless dispatch service in a full duplex wireless telephone system includes forward and reverse link pairs assigned to each voice communication device in a dispatch system. Depending on whether a device is talking or listening, one of the links for that device can be idled to conserve system energy, thereby approximating a half duplex system.

Abstract: A method and apparatus for delivering media to a group of target communicati on 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 replicat es and transmits one copy of the media to each of the target recipients that ar e assigned to dedicated channels, but multicasts one copy of the media to the target recipients that are assigned to a shared channel.

Abstract: A method and apparatus for removing a member from 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 remove the member list from the active group call. The method and apparatus further provides for announcing each member in the member list that they are being removed from the group call, receiving acknowledgement from each member in the member list, and sending a response to the request, indicating that the member list has been removed.

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.

Abstract: A method and apparatus for terminating a member from a group call in a group communication network provides for receiving an indication from a user who wishes to terminate participation in a group call and sending a request to a server to terminate the user from the group call. The method and apparatus further provides for the server to receive the request for terminating a user from a group call, terminate the user from the group call, and send a response indicating that the user is terminated from the group call.

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 signaling even when mobiles are dormant and no traffic channel is active.

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.
