Question: What is a key requirement for mechanisms handling RAN (Radio Access Network) user plane congestions in telecom networks?
Option 1: Resilience to rapid changes in the level of congestion, ensuring adaptability.
Option 2: Prioritization of all UE (User Equipment) traffic equally during congestion.
Option 3: Immediate release of all non-essential network resources upon congestion detection.
Option 4: Mandatory escalation to the core network for all congestion management decisions.
Explanation: Effective management of RAN user plane congestion requires mechanisms that can swiftly adapt to fluctuating congestion levels. This ensures that the network's response remains effective as conditions change, preventing further degradation of service quality. Resilience to rapid changes is crucial for maintaining optimal network performance during congested periods.
