Question: What happens to the SCG Counter value when a Master eNodeB (MeNB) decides to re-start the offloading to the same Secondary eNodeB (SeNB) after previously turning off the offload connection?
Option 1: The SCG Counter value is reset to '0' to restart the S-KeNB calculation.
Option 2: The SCG Counter value remains the same as before the offload was turned off.
Option 3: The MeNB randomly generates a new SCG Counter value for security enhancement.
Option 4: The SCG Counter value continues to increment from its last value, ensuring the computed S-KeNB remains fresh.
Explanation: This is because maintaining freshness of the S-KeNB is crucial. Resetting or keeping the counter static could lead to reusing a similar security key, which is insecure. Random generation isn't a mentioned procedure. Continuously incrementing ensures the security context (S-KeNB) remains unique and secure, aligning with telecom network principles for maintaining freshness of security keys.
