Media-specific floor control for push-to-X communication
First Claim
1. A method of floor control in a Push-to-Talk communications system comprising:
- transmitting, from a mobile station, a floor control message via a floor control channel, said floor control message having a subtype field designating whether the floor control message is media specific, and where the floor control message is media specific, a media bit map indicating one of a plurality of media type designators.

Abstract
In the various embodiments of the present invention, a method of floor control in a PTX communications system comprises transmitting a floor control message via a floor control channel (905) wherein the floor control message consists of media designation fields (1003) for any possible requested media type. The media types preferred for the given requested PTX session are designated by populating the corresponding media type designators (1003) within the floor control message.
The Real Time Control Protocol (RTCP) may be used for the floor control messaging channel and is independent from the requested media streams (217) which are typically Real-time Transport Protocol (RTP) media streams. Support may be provided for older mobiles that do not support each type of RTP media stream, but will still receive and interpret the RTCP floor control messaging, which in the embodiments of the present invention, is common for all media types.
