Question: What actions does the IWF floor control server's floor control arbitration logic take when deciding to release the floor in an MCPTT-LMR interworking scenario?
Option 1: Requests the media distributor to continue forwarding RTP media packets and enters the 'G: Floor Idle' state.
Option 2: Enters the 'G: Floor Idle' state without notifying the media distributor.
Option 3: Requests the media distributor to stop forwarding RTP media packets and then enters the 'G: Floor Idle' state.
Option 4: Notifies all UE devices to release their transmission buffers before entering the 'G: Floor Idle' state.
Explanation: In an MCPTT-LMR interworking scenario, efficient management of floor control is crucial for seamless communication. When the IWF decides to release the floor, it must ensure that media transmission is halted to prevent unnecessary data flow. By requesting the media distributor to stop forwarding RTP media packets, the IWF prevents further media transmission. Subsequently, entering the 'G: Floor Idle' state indicates that the floor is no longer in use, signaling availability for new transmissions. This two-step process ensures orderly management of the communication floor, highlighting the importance of coordinated control and state management in telecom networks.
