Question: What is a key objective of the 5G system in terms of control plane efficiency?
Option 1: Minimize signalling required prior to user data transmission.
Option 2: Maximize signalling overhead to ensure reliable data transmission.
Option 3: Maintain a constant level of signalling regardless of data transmission volume.
Option 4: Increase signalling complexity to support advanced features.
Explanation: The 5G system aims to reduce the amount of signalling required before user data transmission, which is essential for efficient control plane operation. This objective helps minimize latency and optimize network resources, ultimately enhancing the overall user experience.
