Question: In the NG-RAN architecture, what is the primary purpose of Control Plane protocols over Uu and NG interfaces?
Option 1: To efficiently carry user data through the access stratum for PDU Sessions.
Option 2: To control PDU Sessions, manage UE-network connections, and handle procedures like handover and resource allocation.
Option 3: To provide a secure authentication framework for User Equipment (UE) on the network.
Option 4: To optimize network resources for non-IP data transmission in IoT devices.
Explanation: Control Plane protocols manage and control aspects of the UE-network connection, including requesting services, handling handovers, and allocating transmission resources, distinct from User Plane's focus on carrying user data.
