🌐 Registration of UE’s with the Core Network

1. Open the SBA Simulator Dashboard and verify the NF List, Configuration Panel, Logs, and Terminal are visible.
2. Click Terminal and run docker compose -f docker-compose.yml up -d to deploy all core network NFs.
3. Run docker compose -f docker-compose-gnb.yml up -d to bring the gNB (base station) online.
4. Monitor container health with watch docker compose -f docker-compose.yml ps -a until all show running.
5. From the NF palette, select each NF (NRF first, then UDM, AUSF, SMF, UPF, AMF), configure IP/Port, and click Start NF.
6. Wait 4–5 seconds per NF for stabilization, then verify startup logs show "NF ready to accept connections".
7. Select gNB from the palette, configure it, and start it — confirm NGAP and GTP-U connections in logs.
8. Select UE, enter IMSI/Key/OPc/DNN/SST matching the UDR subscriber profile, and click Start UE.
9. Open the UE terminal and run ping -I oaitun_ue1 8.8.8.8 -c4 to validate end-to-end connectivity.
10. Run iperf3 -B <UE_ip> -c <ext-dn_ip> to measure throughput, and add -R flag for RTT.
