Your First 5G UE Registration

Boot a 5G core from scratch, start a gNB, and register your first UE. Watch the 5G-AKA authentication flow unfold across NRF, AMF, AUSF and UDM.

Scenario
You have console access to a fresh sandbox. No network functions are running yet. Your job is to: 1. Boot the Open5GS core services. 2. Start the gNB simulator and bring up NG Setup with the AMF. 3. Register a UE (IMSI 999700000000001) and observe every step of the 5G-AKA authentication. 4. Verify the UE is in CM-CONNECTED state. This lab teaches you the order in which NFs must start, why the NRF boots first, and what actually happens on the wire during a 5G Registration procedure.

What you'll do

  1. Start Open5GS core services
  2. Start the gNB simulator
  3. Register UE 999700000000001
  4. Verify UE is registered
