Abstract
Methods of enabling non-Push-To-Talk (PTT) enabled devices, configured for full-duplex communication, to participate in a PTT-over-Cellular (PoC) session that includes a PTT enabled device, are presented including: detecting start of speech from the non-PTT enabled device; generating a floor control request on behalf of the at least one non-PTT enabled device; negotiating the floor control request based on a device priority; generating a floor control response for the at least one non-PTT enabled device; and generating a first floor control state for the PoC session. In some embodiments, methods further include: buffering RTP packets in a media buffer, the RTP packets corresponding to speech received from the non-PTT enabled device; if the floor control request is granted, sending the RTP packets to the PoC session; and if the floor control request is denied, discarding the RTP packets.
