Level 6
5G QoS & Policy Framework
Master the 5G QoS architecture — QoS flows, 5QI tables, GBR vs non-GBR, reflective QoS, PCF policy control, PCC rules, charging with CHF, and real-world policy design for services like video throttling and gaming.

QoS Architecture
0/7Master the 5G QoS model — compare EPS bearers with QoS flows, understand QFI, 5QI tables, GBR vs non-GBR, reflective QoS, and practice selecting the right 5QI for real use cases.
QoS model: EPS bearer (4G) vs QoS flow (5G)
Side-by-side comparison of 4G EPS bearer-based QoS and 5G flow-based QoS — why the change and what it enables.
lesson3 min
QoS flow, QFI, and QoS rules
Understand QoS flows within a PDU session, QoS Flow Identifier (QFI), and how QoS rules map traffic to flows.
lesson3 min
5QI table: standardized and non-standardized
Interactive lookup table of all standardized 5QI values — resource type, priority, delay budget, and error rate.
lesson3 min
GBR vs non-GBR vs delay-critical GBR
Compare guaranteed bit rate, non-GBR, and delay-critical GBR flows with real use cases for each.
lesson3 min
Reflective QoS
Animated walkthrough of reflective QoS — how the UE derives uplink QoS rules from downlink traffic.
animation3 min
Lab: Select the right 5QI for each use case
Scenario matching exercise — given a service (VoNR, gaming, IoT, video), pick the correct 5QI value.
lab5 min
Quiz: QoS Architecture
Test your knowledge of QoS flows, 5QI, GBR types, and reflective QoS.
quiz3 min
Policy Framework
0/7Master 5G policy control — PCF architecture, AM/SM/UE policies, PCC rules, charging with CHF, and design real-world policies for services like video throttling and gaming.
PCF and policy control architecture
Architecture diagram of PCF and its interfaces — Npcf services, N7/N15, and how policy decisions are enforced.
lesson3 min
AM Policy, SM Policy, UE Policy
Compare the three policy types — what each controls, who creates them, and when they are applied.
lesson3 min
PCC rules and how they're applied
Animated flow: PCF creates PCC rule → SMF receives → QoS flow created → UPF enforces.
animation3 min
Charging: online vs offline in 5G (CHF)
Flow diagram of converged charging with CHF — online (real-time) vs offline (CDR-based) in 5G.
lesson3 min
Real-world: How an operator throttles video to 480p
End-to-end policy flow: subscriber triggers video → PCF applies throttle rule → SMF → UPF enforces.
lesson3 min
Lab: Design a QoS policy for a gaming service
Policy configuration exercise — select 5QI, set GBR, define PCC rules, and choose charging model.
