Abstract

A wireless communication device, and a method thereof, for media burst control of discrete content for a push-to-cellular communication. One circuit of device communicates continuous data via a real time data, such as RTP. Another circuit communicates control information associated with the continuous data via a real time control protocol, such as RTCP. A third circuit communicates discrete data and control information associated with the discrete data via a non-real time protocol, such as MSRP. A request signal for floor control is transmitted by a first device and received by a second device via a non-real time protocol associated with discrete media. The discrete media is then transmitted by the first device and received by the second device via the non-real time protocol.

Claims

1. A method of a wireless communication device for media burst control of discrete content for a push-to-cellular communication, the method comprising:

transmitting a request signal for floor control via a non-real time protocol associated with discrete media, wherein the discrete media includes at least one image; and

transmitting the discrete media via the non-real time protocol after transmitting the request signal for floor control via the non-real time protocol;

transmitting a release signal for floor control via the non-real time protocol; and

receiving an idle signal for floor control via the non-real time protocol in response to transmitting the release signal for floor control via the non-real time protocol.

2. The method of claim 1, further comprising:

receiving a grant signal for floor control via the non-real time protocol in response to transmitting the request signal for floor control via the non-real time protocol; and

receiving an acknowledgment signal of the discrete media via the non-real time protocol in response to transmitting the discrete media via the non-real time protocol.

3. The method of claim 1, further comprising:

transmitting a request signal for floor control via a real time control protocol associated with continuous media; and

transmitting the continuous media via a real time data protocol after transmitting the request signal for floor control via the real time control protocol.

4. The method of claim 1, wherein:

transmitting a request signal for floor control via a non-real time protocol includes transmitting the request signal for floor control via a message session relay protocol; and

transmitting discrete media via the non-real time protocol includes transmitting the discrete media via the message session relay protocol.

5. The method of claim 1, wherein transmitting a request signal for floor control includes transmitting a message by using an existing non-real time protocol command, the message including a header specifying an application control type and a body providing floor control data, the application control type being an application specific MIME type as part of an accept types field in the header.

6. The method of claim 1, wherein transmitting a request signal for floor control includes transmitting a message by using an additional non-real time protocol command, the message including a header supporting at least one floor control requirement and a body providing floor control data.

7. A method of a wireless communication device for media burst control of discrete content for a push-to-cellular communication, the method comprising:

receiving a request signal for floor control via a non-real time protocol associated with discrete media, wherein the discrete media includes at least one image; and

receiving the discrete media via the non-real time protocol after receiving the request signal for floor control via the non-real time protocol;

receiving a release signal for floor control via the non-real time protocol; and

transmitting an idle signal for floor control via the non-real time protocol in response to receiving the release signal for floor control via the non-real time protocol.

8. The method of claim 7, further comprising:

transmitting a grant signal for floor control via the non-real time protocol in response to receiving the request signal for floor control via the non-real time protocol; and

transmitting an acknowledgment signal of the discrete media via the non-real time protocol in response to receiving the discrete media via the non-real time protocol.

9. The method of claim 7, further comprising:

receiving a request signal for floor control via a real time control protocol associated with continuous media; and

receiving the continuous media via a real time data protocol after receiving the request signal for floor control via the real time control protocol.

10. The method of claim 7, wherein:

receiving a request signal for floor control via a non-real time protocol includes receiving the request signal for floor control via a message session relay protocol; and

receiving discrete media via the non-real time protocol includes receiving the discrete media via the message session relay protocol.

11. The method of claim 7, wherein receiving a request signal for floor control includes receiving a message by using an existing non-real time protocol command, the message including a header specifying an application control type and a body providing floor control data, the application control type being an application specific MIME type as part of an accept types field in the header.

12. The method of claim 7, wherein receiving a request signal for floor control includes receiving a message by using an additional non-real time protocol command, the message including a header supporting at least one floor control requirement and a body providing floor control data.

13. A wireless communication device for media burst control of discrete content for a push-to-cellular communication comprising:

a first circuit configured to communicate continuous data via a real time data;

a second circuit configured to communicate control information associated with the continuous data via a real time control protocol; and

a third circuit configured to communicate discrete data and control information associated with the discrete data via a non-real time protocol, wherein the discrete data includes at least one image;

wherein the control information associated with the discrete data includes floor control signals; and

wherein the floor control signals includes a floor control request signal, a floor control release signal, and a floor control idle signal.

14. The wireless communication device of claim 13, wherein the continuous data includes voice media and video media.

15. The wireless communication device of claim 13, wherein the third circuit communicates the discrete data via a first command of the non-real time protocol and the control information associated with the discrete data via a second command of the non-real time protocol, the first and second commands being different from each other.

16. The wireless communication device of claim 13, wherein the third circuit communicates the discrete data via a first sub-type of a particular command of the non-real time protocol and the control information associated with the discrete data via a second sub-type of the particular command of the non-real time protocol.

17. The wireless communication device of claim 13, wherein the real time data protocol is RTP, the real time control protocol is RTCP, and the non-real time protocol is MSRP.

18. The method of claim 13, wherein the third circuit communicates a message by using an existing non-real time protocol command, the message including a header specifying an application control type and a body providing floor control data, the application control type being an application specific MIME type as part of an accept types field in the header.

19. The method of claim 13, wherein communicates a message by using an additional non-real time protocol command, the message including a header supporting at least one floor control requirement and a body providing floor control data.
