Question: What is the primary objective of Overload Control in the context of interactions between Control Plane (CP) and User Plane (UP) nodes?
Option 1: To prioritize traffic based on Quality of Service (QoS) requirements across all network nodes.
Option 2: To dynamically adjust the signaling capacity of a UP function to match fluctuating network demands.
Option 3: To reduce incoming signaling load at an overloaded UP function by instructing peer CP functions to decrease traffic transmission, thereby preventing network-wide impact.
Option 4: To implement load balancing across multiple UP functions to prevent any single point of failure.
Explanation: Overload Control is designed to mitigate the effects of an overloaded User Plane (UP) function by proactively reducing the incoming signaling traffic at its source, thus preventing diminished performance and unnecessary resource utilization within the network.
