Abstract
A method for providing a push-to-talk communication session includes facilitating a push-to-talk communication session among a full duplex endpoint supporting simultaneous two-way communication and a plurality of half duplex endpoints. Communications are received from and transmitted to the full duplex endpoint along a two-way communications path. The method includes blocking communications received from the full duplex endpoint while one of the plurality of half duplex endpoints has floor control in the communication session and receiving from the full duplex endpoint in the two-way communications path a floor control signal comprising a request to transmit communications in the communication session. The method includes, in response to receiving the floor control signal, providing floor control to the full duplex endpoint and transmitting to the plurality of half duplex endpoints communications received from the full duplex endpoint.
