    • 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.
    • 一种用于提供即按即说通信会话的方法包括促进支持同时双向通信的全双工端点和多个半双工端点之间的即按即说通信会话。 通信沿着双向通信路径从全双工端点接收并发送到全双工端点。 该方法包括阻止从全双工端点接收的通信,而多个半双工端点中的一个在通信会话中具有楼层控制,并且在双向通信路径中从全双工端点接收包括发送请求的楼层控制信号 通信会话中的通信。 该方法包括响应于接收到楼层控制信号,向全双工端点提供楼层控制,并向多个半双工端点发送从全双工端点接收的通信。
