Patent abstract
A push-to-talk communications device (PCD) provides improved push-to-talk (PTT) communications. The PCD may include a PTT activator and a PTT module having a buffer and communications logic for providing full duplex PTT communications. In a Point-to-Point PTT mode of operation, PTT communications are performed between two PCDs with the PCDs exercising floor control. After the establishment of communications between the PCDs, the PCDs may enter a PTT talk mode wherein messages are transmitted between the PCDs in real time when a PTT activator is engaged. A PCD may also enter a group PTT mode wherein a PTT server exercises floor control between an initiating PCD and multiple target PCDs.
