ABSTRACT:
A push-to-talk (PTT) method for optimizing talk burst control in a PTT communication network is provided. The method comprises transmitting a talk burst inquiry from a first PTT terminal to a PTT server requesting a talk burst control message to determine a talk burst state of the first PTT terminal; and 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, wherein the talk burst state indicates whether a talk burst request is granted to a second PTT terminal.
