Abstract

An apparatus, architecture and method for floor control in a Push-to-Talk system. A mobile station (203) may transmit a floor request message or messages and request multiple floors. Each floor may correspond to a media type having multiple media streams. A PoC server (201) assigns a priority to media types and/or media streams such that for example, a mobile station (203) may have a floor to transmit a video clip having audio and video streams to a talk group (207), and a member of the talk group may have a floor to transmit audio voice commentary on the media to the talk group (207). The embodiments of the present invention enable multimedia communication use cases without the need for duplication of the state machine at each node, thereby conserving resources.

Claims

1. A mobile station of a dispatch communication system comprising:

a transceiver configured to communicate with at least one remote device for a session having a plurality of floors, each floor being associated with a media type.

2. The mobile station of claim 1, wherein each media type includes one of a white board media, an audio media, a video media, and an image media, a multimedia, and a commentary media.

3. The mobile station of claim 1, further comprising an activation sensor configured to indicate a particular floor of the session.

4. The mobile station of claim 1, further comprising a first activation sensor configured to indicate a first floor of the session and a second activation sensor configured to indicate a second floor of the session.

5. The mobile station of claim 1, further comprising an activation sensor having a first position associated with a first floor of the session and a second position associated with a second floor of the session.

6. The mobile station of claim 1, wherein said media type comprises a plurality of media streams.

7. The mobile station of claim 1, wherein said session comprises transmitting at least one invite message having a priority associated with at least one of said media type and a media stream.

8. The mobile station of claim 1, wherein said invite message is a Session Initiation Protocol message.

9. The mobile station of claim 1, wherein said invite message comprises Session Description Protocol records.

10. The mobile station of claim 1, wherein said session comprises a Packet Data Context of a GPRS cellular network.

11. A method for a communication device of a dispatch communication system comprising:

participating in a session having a plurality of floors, each floor being associated with a media type.

12. The method of claim 11, further comprising:

obtaining control of a particular floor of the session; and

providing a first content to the particular floor of the session in response to obtaining control of the particular floor.

13. The method of claim 11, further comprising:

releasing control of a particular floor of the session; and

receiving content from the particular floor of the session after releasing control of the particular floor.

14. The method of claim 11, further comprising:

obtaining control of a first floor of the session; and

providing a first content to the first floor of the session while receiving a second content from a second floor of the session.

15. The method of claim 11, further comprising:

releasing control of a first floor of the session; and

receiving a first content from the first floor of the session while providing a second content to a second floor of the session.

16. The method of claim 11, further comprising:

obtaining control of a first floor and a second floor of the session; and

providing a first content to the first floor and a second content to the second floor of the session concurrently in response to obtaining control of the particular floor.

17. The method of claim 11, further comprising:

releasing control of a first floor and a second floor of the session; and

receiving a first content from the first floor and a second content from the second floor of the session concurrently after releasing control of the first floor and the second floor.

18. The method of claim 17, wherein receiving content for the first floor and the second floor of the session concurrently comprises:

receiving the first content from the first floor controlled by a first device; and

receiving the second content from the second floor controlled by a second device.

19. The method of claim 11, wherein participating in a session having a plurality of floors includes participating in the session in which each media type includes one of a white board media, an audio media, a video media, and an image media, a multimedia, and a commentary media.

20. A server of a dispatch communication system comprising:

a transceiver configured to receive a floor request message associated with a media resource comprising at least one media stream, and further configured to assign a priority to at least one of said media resource and said at least one media stream.

21. The server of claim 20, wherein said floor request message comprises an invite message.

22. The server of claim 21, wherein said invite message is a Session Initiation Protocol message.

23. The server of claim 21, wherein said invite message comprises Session Description Protocol records.
