ABSTRACT:
A method, PT client device and PT server device for controlling transmission of media data, are discussed. According to an embodiment, the method includes sending, by a PT client, media data to a PT server after receiving a talk burst grant from the PT server in response to a talk burst request message; entering, by the PT client, a first operation state after receiving a media burst revoke message from the PT server, wherein the PT client in the first operation state is unable to request permission to send media data to the PT server; and entering, by the PT client, a second operation state after receiving a media burst idle message from the PT server while the PT client is in the first operation state, wherein the PT client in the second operation state is able to request permission to send media data to the PT server.
