Question: Upon receiving a Floor Request from a permitted MCPTT floor participant, what action does the IWF floor control server take regarding the previously granted MCPTT floor participant?
Option 1: Sends a Floor Granted message with specific details (e.g., Duration field with T12 timer value, granted priority) and remains in the 'D: Floor Taken' state.
Option 2: Immediately revokes the floor from the previous participant without sending any notification messages.
Option 3: Requests additional information from the new requesting participant before making a decision on floor control.
Option 4: Enters a 'Pending' state, delaying the decision until further assessment of the request.
Explanation: This action is in line with the floor control arbitration logic's responsibility to manage and coordinate floor requests efficiently. By sending a Floor Granted message with detailed information (such as the T12 timer value for 'Stop talking dual' and the granted priority), the server ensures a smooth transition of the floor, maintaining order in the communication session. Remaining in the 'D: Floor Taken' state indicates that the floor is still actively engaged, just by a different participant now. This approach supports seamless communication, especially critical in Mission Critical Push To Talk (MCPTT) scenarios where timely and coordinated communication is paramount.
