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: 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 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: A METHOD AND APPARATUS FOR JOINING A USER TO A CALL IN A GROUP COMMUNICATION NETWORK (100) PROVIDES FOR RECEIVING AN INDICATION FROM A USER WHO WISHES TO INITIATE A GROUP CALL AND SENDING A REQUEST TO A SERVER (112) 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 (112) INDICATING THAT THE GROUP CALL IS IN PROGRESS, ALERTING THE USER OF BEING ADDED TO THE GROUP CALL, AND RECEIVING MEDIA FROM THE SERVER (112) AFTER A TRAFFIC CHANNEL IS RE-ESTABLISHED. THE METHOD AND APPARATUS ALSO PROVIDE 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.(FIG 16)

Abstract: A method and device for terminating a user from a group call in a group communication network is disclosed. The method includes the steps of (a) receiving an indication (802) from a user who wishes to terminate their participation in a group call, (b) sending a request (804) to a server (806) to terminate the user from the group call, and (c) sending a response (808) to the user indicating that the user has been terminated (810) from the group call.
