Question: Upon receiving a `DLDedicatedMessageSegment` message, what action(s) does the UE (User Equipment) take if it has received all segments of the message?
Option 1: Store all segments in `rrc-MessageSegmentContainer` indefinitely.
Option 2: Assemble the message from the received segments but only process it if it's an RRCReconfiguration message.
Option 3: Discard all segments without assembling or processing the message.
Option 4: Assemble the message from the received segments, process it according to its type (RRCReconfiguration or RRCResume), and then discard all segments.
Explanation: This is the correct sequence of actions as per the specified behavior. The UE must first assemble the complete message from all received segments. Then, it processes this assembled message based on its type, following specific protocols for either RRCReconfiguration (as outlined in 5.3.5.3) or RRCResume messages (as in 5.3.13.4). Finally, after successful processing, the UE discards all stored segments to maintain efficiency and storage management. This comprehensive approach ensures the UE handles messages effectively while minimizing unnecessary data retention.
