free5GC 5GC & srsRAN 5G with ZeroMQ UE / RAN Sample Configuration

srsRAN_Project and srsRAN_4G software suites include a virtual radio which uses the ZeroMQ networking library to transfer radio samples between applications. Therefore, in order to use U-Plane's DN (Data Network) as a trial, I built a simulation environment for the 5GC mobile network. This briefly describes the overall and configuration files in the Proxmox VE environment.

Overview of free5GC 5GC Simulation Mobile Network

I created a 5GC mobile network (Internet reachable) for simulation with the aim of creating an environment in which packets can be sent end-to-end with one DN for one DNN.

The following minimum configuration was set as a condition.

Only one each for C-Plane, U-Plane and UE.

The built simulation environment is as follows.

The 5GC / UE / RAN used are as follows.

5GC - free5GC v3.4.3 (2024.11.08) - https://github.com/free5gc/free5gc
UPF - go-upf v1.2.3 (2024.11.04) - https://github.com/free5gc/go-upf
(UPF) - gtp5g v0.9.3 (2024.11.06) - https://github.com/free5gc/gtp5g
RAN - srsRAN Project (2024.10.14) - https://github.com/srsran/srsRAN_Project
UE (NR-UE) - srsRAN 4G (2024.02.01) - https://github.com/srsran/srsRAN_4G

Each VMs are as follows.

VM	SW & Role	IP address	OS	CPU <br> (Min)	Mem <br> (Min)	HDD <br> (Min)
VM1	free5GC 5GC C-Plane	192.168.0.141/24	Ubuntu 24.04	1	2GB	20GB
VM2	free5GC 5GC U-Plane	192.168.0.142/24	Ubuntu 24.04	1	1GB	20GB
VM3	srsRAN Project ZMQ RAN<br>(gNodeB)	192.168.0.121/24	Ubuntu 24.04	2	4GB	10GB
VM4	srsRAN 4G ZMQ UE<br>(NR-UE)	192.168.0.122/24	Ubuntu 22.04	1	2GB	10GB

AMF & SMF addresses are as follows.

NF	IP address	IP address on SBI	Supported S-NSSAI
AMF	192.168.0.141	127.0.0.18	SST:1, SD:0x000001
SMF	192.168.0.141	127.0.0.2	SST:1, SD:0x000001

Subscriber Information (other information is the same) is as follows.

UE	IMSI	DNN	OP/OPc	S-NSSAI
UE (NR-UE)	001010000000000	internet	OPc	SST:1, SD:0x000001

I registered these information with the free5GC WebUI. In addition, 3GPP TS 35.208 "4.3 Test Sets" is published by 3GPP as test data for the 3GPP authentication and key generation functions (MILENAGE).

DN is as follows.

DN	S-NSSAI	TUNnel interface of DN	DNN	TUNnel interface of UE
10.60.0.0/16	SST:1 <br> SD:0x000001	upfgtp	internet	tun_srsue

The main information of gNodeB is as follows.

MCC	MNC	TAC	gNodeB ID
001	01	1	0x19b

Additional information.

free5GC 5GC U-Plane worked fine on Raspberry Pi 4 Model B. I used Ubuntu 20.04 (64bit) for Raspberry Pi 4 as the OS. I think it would be convenient to place a compact U-Plane in the edge environment and use it as an end-point for DN.

In addition, I have not confirmed the communication performance.

Changes in configuration files of free5GC 5GC and srsRAN 5G ZMQ UE / RAN

Please refer to the following for building free5GC and srsRAN 5G ZMQ UE / RAN respectively.

free5GC v3.4.3 (2024.11.08) - https://free5gc.org/guide/
go-upf v1.2.3 (2024.11.04) - https://free5gc.org/guide/
gtp5g v0.9.3 (2024.11.06) - https://free5gc.org/guide/
srsRAN Project (RAN) (2024.10.14) - https://github.com/s5uishida/build_srsran_5g_zmq
srsRAN 4G (UE) (2024.02.01) - https://github.com/s5uishida/build_srsran_4g_zmq_disable_rf_plugins

Changes in configuration files of free5GC 5GC C-Plane

The combination of DNN and S-NSSAI parameters can be used in the logic that selects UPF as the connection destination by PFCP.

DNN
S-NSSAI

For the sake of simplicity, This time, only DNN will be changed. S-NSSAI is fixed as SST=1 and SD=000001.

Network settings of free5GC 5GC

Network settings of free5GC 5GC U-Plane

First, uncomment the next line in the /etc/sysctl.conf file and reflect it in the OS.

net.ipv4.ip_forward=1

# sysctl -p

Next, configure the TUNnel interface and NAPT.

# iptables -t nat -A POSTROUTING -s 10.60.0.0/16 ! -o upfgtp -j MASQUERADE

Build free5GC and srsRAN 5G ZMQ UE / RAN

Please refer to the following for building free5GC and srsRAN 5G ZMQ UE / RAN respectively.

free5GC v3.4.3 (2024.11.08) - https://free5gc.org/guide/
go-upf v1.2.3 (2024.11.04) - https://free5gc.org/guide/
gtp5g v0.9.3 (2024.11.06) - https://free5gc.org/guide/
srsRAN Project (RAN) (2024.10.14) - https://github.com/s5uishida/build_srsran_5g_zmq
srsRAN 4G (UE) (2024.02.01) - https://github.com/s5uishida/build_srsran_4g_zmq_disable_rf_plugins

Install MongoDB on free5GC 5GC C-Plane machine. It is not necessary to install MongoDB on free5GC 5GC U-Plane machines. MongoDB Compass is a convenient tool to look at the MongoDB database.

Note. The installation guide also includes instructions on building the latest committed version.

Build go-upf

Please refer to the free5GC guide at the above URL for building free5GC UPF. Below show only the differences in the procedure.

# git clone https://github.com/free5gc/go-upf.git
# cd go-upf
# CGO_ENABLED=0 go build -o upf cmd/main.go
# ls upf
upf
# wget https://raw.githubusercontent.com/free5gc/free5gc/main/config/upfcfg.yaml

Run free5GC 5GC and srsRAN 5G ZMQ UE / RAN

First run the 5GC, then the RAN, and the UE.

Run free5GC 5GC C-Plane

First, run free5GC 5GC C-Plane.

free5GC 5GC C-Plane

Create the following shell script and run it.

#!/usr/bin/env bash

PID_LIST=()

NF_LIST="nrf amf smf udr pcf udm nssf ausf chf"

export GIN_MODE=release

for NF in ${NF_LIST}; do
    ./bin/${NF} &
    PID_LIST+=($!)
    sleep 1
done

function terminate()
{
    sudo kill -SIGTERM ${PID_LIST[${#PID_LIST[@]}-2]} ${PID_LIST[${#PID_LIST[@]}-1]}
    sleep 2
}

trap terminate SIGINT
wait ${PID_LIST}

Run free5GC 5GC U-Plane

Next, run free5GC 5GC U-Plane.

free5GC 5GC U-Plane

# cd go-upf
# ./upf -c upfcfg.yaml

Run srsRAN 5G ZMQ RAN

Run srsRAN 5G ZMQ RAN and connect to free5GC 5GC.

# cd srsRAN_Project/build/apps/gnb
# ./gnb -c gnb_zmq.yaml

You could now create the end-to-end TUN interface on the DN and send any packets on the network.

In investigating 5G SA, I have built a simulation environment and can now use a very useful system for investigating 5GC and MEC of 5G SA mobile network. I would like to thank the excellent developers and all the contributors of free5GC, srsRAN Project and srsRAN 4G.
