Question: When an IWF (Interworking Function) floor control server grants floor to an IWF floor participant, what action(s) does it perform regarding timers and SSRC (Synchronization Source Identifier)?
Option 1: Starts timer T4 (Inactivity) and generates a new SSRC for the granted participant.
Option 2: Stops timer T7 (Floor Idle) only and uses an existing SSRC for the granted participant.
Option 3: Stops both timers T4 (Inactivity) and T7 (Floor Idle), and generates a new SSRC if granting to an IWF floor participant, otherwise stores the participant's SSRC.
Option 4: Enters the 'G: Floor Taken' state without modifying any timers or SSRC for the granted participant.
Explanation: When granting floor access to an IWF floor participant, the server must halt inactivity and idle timers (T4 and T7) to ensure uninterrupted communication. Additionally, managing the SSRC is crucial for synchronization; thus, generating a new SSRC for IWF participants or storing the existing one for non-IWF ensures proper media handling, aligning with efficient floor control management in MCPTT scenarios.
