Question: Upon expiry of Timer T3 (Stop talking grace) when a Floor Revoke message has been sent, what actions does the floor control arbitration logic in the IWF floor control server take regarding the general state machine and its own state?
Option 1: - Transitions to 'G: Floor Granted' state - Notifies MCPTT client of 'G: Floor Requested' state
Option 2: - Enters 'G: Idle' state but does not notify the MCPTT client - Remains in the previous state until a new floor request is made
Option 3: - Indicates to the MCPTT client that the general state machine is now 'G: Floor Idle' - Enters the 'G: Idle' state as per specified protocols
Option 4: - Sends another Floor Revoke message before changing states - Transitions to a 'G: Floor Suspended' state temporarily
Explanation: Upon Timer T3 expiry and after sending a Floor Revoke message, the logical steps for the IWF floor control server involve updating both its internal state and notifying the MCPTT client about the change in the general state machine. Specifically, indicating the transition to 'G: Floor Idle' to the client while internally entering the 'G: Idle' state aligns with efficient resource management and clear communication protocols in mission-critical push-to-talk (MCPTT) scenarios, ensuring all parties are aware of the current floor status.
