    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 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 providing an efficient dormant mode for push-to-talk communication devices (102, 104, 106) in a group communication network (100) provides for determining whether the net has been inactive for a predetermined first time period and, if so, causing each member of the net to enter a control-hold mode, wherein each member of the net maintains its dedicated traffic channel. The method further includes the steps of determining whether each member of the net has been in the control-hold mode for a predetermined second time period and, if so, causing each member of the net to enter a dormant mode, wherein each member of the net releases its dedicated traffic channel. The method and apparatus further provides for causing each member of the net to cache its service configuration state before entering the dormant mode.

    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.
