Question: What type of packet delays can be measured using QoS Monitoring for packet delay in a 5G System?
Option 1: Only Uplink (UL) packet delay
Option 2: Only Downlink (DL) packet delay
Option 3: UL packet delay, DL packet delay, or round trip packet delay between UE and PSA UPF
Option 4: None of the above
Explanation: QoS Monitoring for packet delay allows for the measurement of UL packet delay, DL packet delay, or round trip packet delay between User Equipment (UE) and Packet Steering Anchor Point (PSA) User Plane Function (UPF), enabling network operators to monitor and manage packet delay variations in their 5G networks.
