Question: What happens to the AS security algorithms during an intra-gNB-CU/intra-ng-eNB handover if the UE does not receive any indication of new algorithms?
Option 1: The UE switches to a default set of security algorithms.
Option 2: The UE negotiates new security algorithms with the gNB/ng-eNB.
Option 3: The UE continues to use the same AS security algorithms as before the handover.
Option 4: The UE terminates the connection due to security concerns.
Explanation: During an intra-gNB-CU/intra-ng-eNB handover, if the UE does not receive any indication of new AS security algorithms, it will continue to use the same algorithms as before the handover. This ensures continuity and maintains the existing security context, avoiding unnecessary changes or potential security risks.
