Question: What is the primary purpose of the Information Transfer function in the UTRAN Iu interface, as utilized by the Core Network (CN)?
Option 1: To facilitate real-time voice call setup between the CN and RNC.
Option 2: To enable seamless handover of User Equipment (UE) between different Radio Access Networks (RANs).
Option 3: To maintain alignment of configuration data between the CN and UTRAN, ensuring consistency for access control applications.
Option 4: To transmit user data packets efficiently during peak network hours.
Explanation: The Information Transfer function ensures configuration data synchronization between the CN and UTRAN, crucial for consistent geographical definitions across both, particularly for access control relying on Service Area Numbers (SNA) mapping.
