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

0/7

Master 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.

interactive3 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.

interactive3 min

5QI table: standardized and non-standardized

Interactive lookup table of all standardized 5QI values — resource type, priority, delay budget, and error rate.

interactive3 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.

interactive3 min

Reflective QoS

Animated walkthrough of reflective QoS — how the UE derives uplink QoS rules from downlink traffic.

interactive3 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.

Quiz: QoS Architecture

Test your knowledge of QoS flows, 5QI, GBR types, and reflective QoS.

Policy Framework

0/7

Master 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.

interactive3 min

AM Policy, SM Policy, UE Policy

Compare the three policy types — what each controls, who creates them, and when they are applied.

interactive3 min

PCC rules and how they're applied

Animated flow: PCF creates PCC rule → SMF receives → QoS flow created → UPF enforces.

interactive3 min

Charging: online vs offline in 5G (CHF)

Flow diagram of converged charging with CHF — online (real-time) vs offline (CDR-based) in 5G.

interactive3 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.

lab3 min

Lab: Design a QoS policy for a gaming service

Policy configuration exercise — select 5QI, set GBR, define PCC rules, and choose charging model.
