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.
