Question: Upon granting the floor to an MCPTT (Mission Critical Push To Talk) participant with overriding pre-emptive priority, what action does the IWF (Interworking Function) floor control server perform regarding state machine and SSRC (Synchronization Source Identifier)?
Option 1: Deletes one instance of the 'dual floor control operation' state machine and discards the SSRC of the previous floor participant.
Option 2: Creates one instance of the 'dual floor control operation' state machine and stores the SSRC of the granted floor participant.
Option 3: Enters the 'D: Floor Released' state without modifying the 'dual floor control operation' state machine instances, based on the stored Track Info field.
Option 4: Sends a Floor Request message to all participants to confirm the overriding pre-emptive priority before creating a new state machine instance.
Explanation: When an MCPTT floor participant is granted the floor with an overriding pre-emptive priority, the IWF floor control server initiates a new 'dual floor control operation' to manage the prioritized access efficiently. Storing the SSRC of the granted participant ensures proper identification and management of the ongoing communication session, aligning with the requirements for seamless mission-critical communications. This action reflects the server's role in arbitrating and controlling floor access based on priority, ensuring that high-priority communications are handled appropriately.
