Method and apparatus for floor control in a communication system
First Claim
1. A method for enabling floor control in a communication system, the method comprising the steps of:
- receiving a first message requesting initiation of a PTT session, the first message comprising a communication description protocol packet, the communication description protocol packet comprising a first floor control profile, the first floor control profile comprising at least one of a first set of floor control parameters and a first list of potential floor owners;
accepting the PTT session;
determining a second floor control profile corresponding to the accepted PTT session prior to the PTT session being established, the second floor control profile comprising a second set of floor control parameters and wherein the second floor control profile is substituted for the first floor control profile as a floor control profile for the PTT session;
communicating at least a portion of the second floor control profile prior to the PTT session being established; and
communicating different portions of the second floor control profile to different non-endpoint entities in the communication system and the entire second floor control profile to endpoints participating in the session.

Abstract
Methods for enabling floor control are performed in an endpoint terminal (140, 142, 146) and a session controller (106). The session controller: receives (410) a message requesting a session that includes an SDP packet with a requested floor control profile having a requested set of floor control parameters or a requested list of potential floor owners; accepts (410) the session; determines (420) a final floor control profile having a final set of floor control parameters and a final list of potential floor owners; and communicates at least a portion of the floor control profile within a system (100). The endpoint terminal: communicates a message requesting a session that includes an SDP packet with a requested floor control profile; and receives a message having an SDP packet with a final floor control parameter. The final floor control profile may be the same as or different from the requested floor control profile.

15. Apparatus for enabling floor control in a communications system, comprising:
-
at least one processor; and a memory storing instructions executable by the at least one processor, the instructions comprising the steps of; receiving a first message requesting initiation of a PTT session, the first message comprising a communication description protocol packet, the communication description protocol packet comprising a first floor control profile, the first floor control profile comprising at least one of a first set of floor control parameters and a first list of potential floor owners; accepting the PTT session; determining a second floor control profile corresponding to the accepted PTT session prior to the PTT session being established, the second floor control profile comprising a second set of floor control parameters and wherein the second floor control profile is substituted for the first floor control profile as a floor control profile for the PTT session; communicating at least a portion of the second floor control profile prior to the PTT session being established; and communicating different portions of the second floor control profile to different non-endpoint entities in the communication system and the entire second floor control profile to endpoints participating in the session.

16. A method for enabling floor control in a communication system, the method comprising the steps of:
-
communicating a first message requesting initiation of a PTT session, the first message comprising a communication description protocol packet, the communication description protocol packet comprising a first floor control profile, the first floor control profile comprising at least one of a first set of floor control parameters and a first list of potential floor owners; receiving prior to the PTT session being established a second message responsive to the first message, the second message comprising a communication description protocol packet, the communication description protocol packet comprising a second floor control profile, the second floor control profile comprising a second set of floor control parameters and wherein the second floor control profile is substituted for the first floor control profile as a floor control profile for the PTT session; and communicating different portions of the second floor control profile to different non-endpoint entities in the communication system and the entire second floor control profile to endpoints participating in the session. - View Dependent Claims (17, 18, 19)
