Patent ID: 7809391

Claim:
A method for optimizing talk burst control in a push-to-talk (PTT) communication network by a first PTT terminal that has lost a talk burst control message, the method comprising: transmitting a talk burst inquiry to a PTT server requesting the talk burst control message to determine a talk burst state of the first PTT terminal; receiving from the PTT server the talk burst control message providing the talk burst state of the first PTT terminal, in response to the talk burst inquiry; and receiving a real time protocol (RTP) packet transmitted by a second PTT terminal, wherein the talk burst control message notifies the other PTT terminals that the second PTT terminal has obtained the permission to send the talk burst, wherein the talk burst control message comprises identity of the second PTT terminal, wherein the RTP packet comprises a synchronization source (SSRC) field, and wherein the talk burst inquiry is transmitted by the first PTT terminal, when the first PTT terminal receives a communication from the second PTT terminal without having received the talk burst control message from the PTT server.
