Question: Upon receiving unauthorized RTP media packets from an associated floor participant in an MCPTT (Mission Critical Push To Talk) scenario, what actions does the IWF (InterWorking Function) floor control server take towards the MCPTT client and the network media interface?
Option 1: - Forwards the RTP media packets to the media distributor for broadcasting. - Sends a Floor Grant message to the associated floor participant.
Option 2: - Requests the network media interface to forward the received RTP media packets to all participants. - Enters the 'U: permitted' state without notifying the floor participant.
Option 3: - Ignores the unauthorized RTP media packets without any notification. - Continues in the current state without transitioning.
Option 4: - Requests the network media interface to NOT forward the received RTP media packets to the media distributor. - Sends a Floor Revoke message with a Reject Cause (No permission to send a Media Burst) to the associated floor participant.
Explanation: Option 4 is correct because, upon receiving unauthorized RTP media packets, the IWF floor control server must prevent further unauthorized media transmission and notify the associated floor participant of the revocation of their floor grant due to lack of permission, maintaining controlled and secure communication within MCPTT groups.
