Implementing push-to-talk in a multimedia conferencing system
Systems and methods of providing push-to-talk communication techniques in a multimedia conferencing session are provided. For instance, a push-to-talk mode can be implemented in a conferencing session associated with a conferencing system comprising a plurality of endpoints. At least one of the endpoints can be a full duplex endpoint. A request for transmission capabilities can be received from a first endpoint. Transmission capabilities can be granted to the first endpoint based at least in part on one or more floor control parameters associated with the conferencing session. Subsequent to granting transmission capabilities to the first endpoint, audio data can be provided from the first endpoint to at least one endpoint of the plurality of endpoints in the conferencing session.
1. A computer-implemented method of implementing floor control in a conferencing session, the method comprising:
receiving, by one or more computing devices, a radio resource presence message from a radio gateway, the radio resource presence message indicating an entry of one or more half-duplex endpoints into the conferencing session, wherein the radio resource presence message is received while the conferencing session is operating in a full-duplex mode wherein each endpoint is communicating in the conferencing session using full-duplex communication techniques, wherein the one or more half-duplex endpoints communicate using only half-duplex communication techniques;
in response to receiving the radio resource presence message from the radio gateway, converting, by the one or more computing devices, the conferencing session from the full-duplex mode to a push-to-talk mode by implementing one or more floor control parameters in the conferencing session; and
granting, by the one or more computing devices, transmission capabilities to one or more endpoints based at least in part on the one or more floor control parameters associated with the conferencing session.
2. The computer-implemented method of claim 1 , further comprising receiving, by the one or more computing devices, a transmission capabilities request from a first endpoint of the conferencing session while operating in the push-to-talk mode;
and wherein the granting comprises granting the transmission capabilities to the first endpoint in response to receiving the transmission capabilities request.
3. The computer-implemented method of claim 2 , further comprising, subsequent to granting the transmission capabilities to the first endpoint, providing, by the one or more computing devices, audio data from the first endpoint to at least one other endpoint in the conferencing session.
4. The computer-implemented method of claim 2 , further comprising, responsive to receiving the transmission capabilities request from the first endpoint, determining, by the one or more computing devices, whether to grant the transmission capabilities to the first endpoint based at least in part on the one or more floor control parameters.
5. The computer-implemented method of claim 4 , further comprising revoking, by the one or more computing devices, the transmission capabilities from the first endpoint; and
granting, by the one or more computing devices, the transmission capabilities to a second endpoint based at least in part on the one or more floor control parameters.
6. The computer-implemented method of claim 1 , further comprising:
detecting, by the one or more computing devices, a removal from the conferencing session of the one or more half-duplex endpoints; and
responsive to the detecting, converting, by the one or more computing devices, the conferencing session from the push-to-talk mode to the full-duplex mode by ceasing implementation of the one or more floor control parameters.
7. The computer-implemented method of claim 6 , further comprising, subsequent to converting the conferencing session to the full-duplex mode, allowing, by the one or more computing devices, transmission of audio data without regard for the one or more floor control parameters.
8. The computer-implemented method of claim 1 , wherein at least one of the one or more half-duplex endpoints comprises a two-way radio.
9. A computing system comprising
one or more processors;
one or more memory devices, the one or more memory devices storing computer-readable instructions that when executed by the one or more processors cause the one or more processors to perform operations, the operations comprising:
receiving a radio resource presence message from a radio gateway, the radio resource presence message indicating an entry of one or more half-duplex endpoints into the conferencing session, wherein the radio resource presence message is received while the conferencing session is operating in a full-duplex mode wherein each endpoint is communicating in the conferencing session using full-duplex communication techniques, wherein the one or more half-duplex endpoints communicate using only half-duplex communication techniques;
in response to the receiving, converting the conferencing session from the full-duplex mode to a push-to-talk mode by implementing one or more floor control parameters in the conferencing session; and
granting transmission capabilities to one or more endpoints based at least in part on the one or more floor control parameters associated with the conferencing session.
10. The computing system of claim 9 , the operations further comprising receiving a transmission capabilities request from a first endpoint of the conferencing session while operating in the push-to-talk mode;
and wherein the granting comprises granting the transmission capabilities to the first endpoint in response to receiving the transmission capabilities request.
11. The computing system of claim 9 , the operations further comprising:
detecting a removal from the conferencing session of the one or more half-duplex endpoints; and
responsive to the detecting, converting the conferencing session from the push-to-talk mode to the full-duplex mode by ceasing implementation of the one or more floor control parameters.
12. The computing system of claim 11 , the operations further comprising, subsequent to converting the conferencing session to the full-duplex mode, allowing transmission of audio data without regard for the one or more floor control parameters.
13. The computing system of claim 9 , wherein at least one of the one or more half-duplex endpoints comprises a two-way radio.
14. One or more tangible, non-transitory computer-readable media storing computer-readable instructions that when executed by one or more processors cause the one or more processors to perform operations, the operations comprising:
receiving a radio resource presence message from a radio gateway, the radio resource presence message indicating an entry of one or more half-duplex endpoints into the conferencing session, wherein the radio resource presence message is received while the conferencing session is operating in a full-duplex mode wherein each endpoint is communicating in the conferencing session using full-duplex communication techniques, wherein the one or more half-duplex endpoints communicate using only half-duplex communication techniques;
in response to the receiving, converting the conferencing session from the full-duplex mode to a push-to-talk mode by implementing one or more floor control parameters in the conferencing session; and
