Question: Upon receiving a Floor Release message in an MCPTT (Mission Critical Push To Talk) scenario, what action does the IWF (Interworking Function) floor control server take regarding RTP media packets from the participant that sent the release?
Option 1: It requests the media distributor to continue forwarding RTP media packets at an increased rate.
Option 2: It requests the media distributor to stop forwarding RTP media packets received from the participant.
Option 3: It buffers the RTP media packets temporarily before resuming forwarding.
Option 4: It ignores the Floor Release message for ongoing transmissions.
Explanation: When a Floor Release message is received, indicating that a user has released the floor, the IWF's primary concern is to prevent further unwanted media transmission. Stopping the forwarding of RTP media packets from the releasing participant ensures seamless and controlled communication, adhering to the MCPTT's stringent requirements for mission-critical communications. This action prevents unnecessary network resource usage and maintains the integrity of the current communication session.
