发明名称 METHOD OF BUFFERING TO REDUCE MEDIA LATENCY IN GROUP COMMUNICATIONS ON A WIRELESS COMMUNICATION NETWORK
摘要 A system and method for minimising 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 has a dormant state without an open dedicated traffic channel for communications therefrom and an active state in which the wireless devices opens a dedicated tratBc channel tor an outgoing communication from the wireless telecommunication device, to include a direct communication stream. Either the-wireless telecommunication device or an intermittent communication server for group communication streams can buffer the initial communication data of a group communication stream while die sending and/or receiving wireless telecommunication, device changes from a dormant state to an active state with an open dedicated traffic channel.
