Question: In an MCPTT (Mission Critical Push To Talk) system, when the state is 'U: not permitted and initiating' for a temporary group session, how are Floor Request messages received from the non-controlling MCPTT function handled?
Option 1: Immediately Rejected due to Initialization State
Option 2: Processed Instantly with Priority Over Existing Requests
Option 3: Discarded to Prevent Queue Congestion
Option 4: Added to a Queue Based on the Request's Priority
Explanation: During the 'U: not permitted and initiating' state, the system is waiting for floor control arbitration logic to finalize initialization. To manage incoming requests efficiently without disrupting the setup process, Floor Request messages are not immediately processed or rejected but rather, they are added to a queue. This queuing is based on the priority of each floor request, ensuring that higher-priority requests are addressed first once the system is ready, reflecting standard practices in managing concurrent access in communication systems.
