5G Network Digital Twin with What-If AI

Overview

A live dashboard on a running 5G standalone network. Visitors see real telemetry and ask what-if questions, such as adding more devices or changing bandwidth. The system predicts whether congestion will occur and explains its reasoning. One click on Auto-Optimise reconfigures the network and re-measures it, showing a real before and after. Before deploying private 5G for a factory or warehouse, simulate the scenario first and know the configuration you actually need.

How it works

1. 01

   Live testbed

   OpenAirInterface 5G Standalone with a full core (AMF, SMF, UPF, PCF), a gNB and 8 UEs over RF simulation. Each UE sends traffic that matches a realistic device.

2. 02

   QoS / slicing

   Three tiers (URLLC, eMBB, mMTC), driven through the PCF.

3. 03

   TSN

   IEEE 802.1Qbv time-aware gating (Linux tc-taprio).

4. 04

   Live telemetry

   UE count, throughput, latency, packet loss, PRB use, RSRP / SINR, QoS flow per device and application traffic.

5. 05

   What-If predictor

   Checks a knowledge base of 144 measured scenario combinations. With an exact match, it returns the measured result; otherwise it applies a rule based on the measured capacity ceiling. Every prediction comes with its reasoning trail.

6. 06

   Auto-Optimise

   Recomputes a phase-aligned, proportional TSN gate schedule, applies it, and re-measures latency.
