Part 6. Validate the Setup

1.0

Modify:

  • oai_db.sql (with plain text editor)

    There are 3 UEs pre-configured here. To find them, search for: 001010000000001 and add or edit them as needed.

  • On gNB server, if you want to change the change the MCC and MNC in the gNB config file. ./targets/PROJECTS/GENERIC-NR-5GC/CONF/vnf.sa.band78.fr1.273PRB.Aerial.conf

For reference, use the following:

SIM cards – 4G and 5G reference software (open-cells.com)

Program SIM Card with Open Cells Project application “uicc-v2.6” https://open-cells.com/d5138782a8739209ec5760865b1e53b0/uicc-v2.6.tgz

Use the ADM code specific to the SIM card. If the wrong ADM is used 8 times, the SIM card is permanently locked.

CUE Configuration Setup

Install the “Magic IPERF” application on the UE:

  1. To test with CUE, a test SIM card with Milenage support is required. The following has to be provisioned on the SIM and it has to match the Core Network settings: mcc, mnc, IMSI, Ki, OPc

  2. The APN on the CUE should be configured according to Core Network settings.

  3. Start the DNS (Core network should assign mobile IP address and DNS. If DNS is not assigned, set DNS with other Android app).

This section describes how to run end-to-end traffic from UE to the edge core network.

Note

UE can connect as close as 2-3 meters with a range of 10-15 meters. Connection distance outside of buildings is unverified.

Start CN5G Core Network

sudo sysctl net.ipv4.conf.all.forwarding=1 sudo iptables -P FORWARD ACCEPT cd ~/oai-cn5g docker compose up -d

Start CN5G Edge Application

After the CN5G is started, use the oai-ext-dn container to run IPERF.

# Run on host: start a docker terminal docker exec -it $AERIAL_CUBB_CONTAINER /bin/bash

Follow the Aerial documentation for building and running the cuphycontroller. The following instructions are for building and setting up the environment for running cuphycontroller. The following commands must be run from inside cuBB container.

Configuration files for ARC-OTA can be found in the following shared Google drive.

Aerial configuration files are located in /opt/nvidia/cuBB/cuPHY-CP/cuphycontroller/config.

Before running the cuphycontroller, edit the configuration file (cuphycontroller_P5G_SCF_FXN.yaml) to point at the correct MAC address of the ORU and the correct PCIe address of FH interface of the gNB.

CUE Connecting to 5G Network

Take the CUE out of airplane mode to start the UE attaching to the network. Make sure that the CUE is in airplane mode before starting OAI L2 stack.

Observe 5G Connect Status

See Preamble log in cuphycontroller console output.

Check Core Network log or CUE log to see whether NAS authentication and PDU session succeed.

Running E2E IPERF Traffic

Start ping, iperf, or other network app tests after the PDU session connects successfully.

You can install and run the “Magic IPerf” Android application on the CUE for this purpose.

Ping Test

Ping the UE from the CN:
