Abstract

In an embodiment, a communication device (e.g., a current floor arbitrator of the session, a proxy device, etc.) records a floor arbitration history that tracks one or more floor grants and one or more floor denials that occur while a first device is performing a floor arbitration function for the communication session with the communication group, and transmits some or all of the floor arbitration history to a second device during the communication session. The second device (e.g., a new floor arbitrator for the session, a late or re-joining participant to the communication session, etc.) participates in the communication session based at least in part upon the received floor arbitration history (e.g., by factoring the received floor arbitration history into future floor-related decisions, by selectively requesting particular missed portions of the communication session, etc.).
