Patent ID: 7751348

Claim:
A method for providing a push-to-talk communication session, comprising: facilitating a push-to-talk communication session among a full duplex endpoint supporting simultaneous two-way communication and a plurality of half duplex endpoints, wherein communications are received from and transmitted to the full duplex endpoint along a two-way communications path; blocking communications received from the full duplex endpoint while one of the plurality of half duplex endpoints has floor control in the communication session; 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; 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; wherein the full duplex endpoint and the plurality of half duplex endpoints are of different communication networks and are part of a virtual talk group associated with an event; and further comprising determining a maximum floor control amount of time for the full duplex endpoint according to an event type associated with the event.
