Question: What happens to the AS (Access Stratum) security algorithm during an intra-eNB (Evolved Node B) handover if no new selection is received by the UE (User Equipment)?
Option 1: The UE automatically switches to a default, predefined alternative AS security algorithm.
Option 2: The UE continues to use the same AS security algorithms as before the handover.
Option 3: The UE initiates a security reconfiguration process with the MME (Mobility Management Entity) to determine new algorithms.
Option 4: The handover is aborted, and the UE remains connected to the original cell to maintain security integrity.
Explanation: During an intra-eNB handover, if the UE does not receive instructions to change the AS security algorithm, it maintains continuity by using the same algorithms that were in use prior to the handover. This approach ensures seamless security without introducing additional complexity or potential vulnerabilities during the handover process.
