Question: What happens if an AMF receives a rejection to a N2 interface procedure during an ongoing Xn-based handover?
Option 1: The AMF will immediately terminate the handover procedure.
Option 2: The AMF will reattempt the same N2 interface procedure after a random delay.
Option 3: The AMF will ignore the rejection and continue with the handover procedure.
Option 4: The AMF may reattempt the same N2 interface procedure either when the handover is complete or the handover is deemed to have failed.
Explanation: According to the text, if an AMF receives a rejection to a N2 interface procedure during an ongoing Xn-based handover, it may reattempt the same N2 interface procedure either when the handover is complete or the handover is deemed to have failed. This allows the AMF to retry the procedure after the handover has finished or if it fails, ensuring that the necessary signaling can be completed successfully.
