Question: What is the primary objective of the eNB Configuration Update procedure in the context of E-UTRAN's S1 interface?
Option 1: To modify existing User Equipment (UE) contexts for enhanced mobility.
Option 2: To update application-level configuration data for interoperability between eNB and MME.
Option 3: To establish new S1 interface connections for incoming UE requests.
Option 4: To terminate idle UE connections for resource optimization.
Explanation: The eNB Configuration Update procedure is designed to ensure seamless interoperability between the Evolved Node B (eNB) and the Mobility Management Entity (MME) by updating necessary configuration data at the application level, without impacting existing User Equipment (UE) contexts, maintaining operational consistency across the S1 interface without disrupting ongoing UE communications.
