Question: In an MCPTT (Mission Critical Push To Talk) system, when the IWF (Interworking Function) floor control server is in the 'G: Floor Idle' state, which of the following statements about timers is accurate?
Option 1: Only Timer T4 (Inactivity) is running, as the floor is idle.
Option 2: Neither Timer T4 (Inactivity) nor Timer T7 (Floor Idle) can be running in this state.
Option 3: Both Timer T4 (Inactivity) and Timer T7 (Floor Idle) can be running simultaneously.
Option 4: The system must immediately start Timer T4 upon entering this state, pausing any other timer.
Explanation: In the 'G: Floor Idle' state of an MCPTT system's IWF floor control server, no participant has permission to send media. This state allows for the possibility of recent inactivity (hence Timer T4) and also acknowledges the current idle status of the floor (Timer T7). Thus, both timers related to inactivity and floor idleness can indeed be operational at the same time, ensuring the system is prepared to manage both the lack of current transmissions and the duration since the last transmission.
