free5GC 5GC & UERANSIM UE / RAN Sample Configuration - ULCL(Uplink Classifier)

This describes a very simple configuration that uses free5GC and UERANSIM for ULCL(Uplink Classifier).
Instead of go-upf (free5GC UPF), you may use NextMN-UPF as UPF to confirm ULCL.

Overview of free5GC 5GC Simulation Mobile Network

The following minimum configuration was set as a condition.

I-UPF selects the communication paths according to the destination host and network.

The built simulation environment is as follows. In this configuration, I-UPF(VM2) must be reachable to Docker network on local.

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

5GC - free5GC v3.4.3 (2024.09.12) - https://github.com/free5gc/free5gc
UPF - go-upf v1.2.3 (2024.05.11) - https://github.com/free5gc/go-upf
(UPF) - gtp5g v0.8.10 (2024.06.03) - https://github.com/free5gc/gtp5g
UE / RAN - UERANSIM v3.2.6 (2024.08.27) - https://github.com/aligungr/UERANSIM

Each VMs are as follows.	VM #	SW & Role	IP address	OS	Mem (Min)
VM1	free5GC 5GC C-Plane	192.168.0.141/24	Ubuntu 24.04	2GB	20GB
VM2	free5GC 5GC U-Plane (I-UPF)	192.168.0.142/24	Ubuntu 24.04	1GB	10GB
VM3	free5GC 5GC U-Plane (PSA-UPF)	192.168.0.143/24	Ubuntu 24.04	1GB	10GB
VM4	UERANSIM RAN (gNodeB)	192.168.0.131/24	Ubuntu 24.04	1GB	10GB
VM5	UERANSIM UE	192.168.0.132/24	Ubuntu 24.04	1GB	10GB

Subscriber Information (other information is default) is as follows. Note. Please select OP or OPc according to the setting of UERANSIM UE configuration files.	UE	IMSI	DNN	OP/OPc
UE	001010000000000	internet	OPc

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	TUNnel interface of DN	DNN	TUNnel interface of UE
10.60.0.0/16	upfgtp	internet	uesimtun0

The UE routing topology is as follows.

UE --- gNodeB --- I-UPF --- PSA-UPF

The communication paths to be confirmed for each destination IP address are as follows.	Destination IP address	Communication path
google.com	I-UPF --> PSA-UPF --> Internet
8.8.8.8	I-UPF --> Internet
172.17.0.1	I-UPF --> 172.17.0.0/16 (Docker network on local)

Build free5GC and UERANSIM

Please refer to the following for building free5GC and UERANSIM respectively.

free5GC v3.4.3 (2024.09.12) - https://free5gc.org/guide/
go-upf v1.2.3 (2024.05.11) - https://free5gc.org/guide/

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. If it doesn't work properly and you suspect some bug, try updating all NFs by following this update procedure.

Build go-upf

For UPF, select the go-upf version that enables ULCL with the free5GC version selected this time. Please refer to the free5GC guide at the above URL for building free5GC UPF. Below show only the differences in the procedure.

# git clone -b v1.2.3 https://github.com/free5gc/go-upf.git
# cd go-upf

First run the 5GC, then UERANSIM (UE & RAN implementation).

Run free5GC 5GC U-Plane (I-UPF & PSA-UPF)

free5GC 5GC U-Plane (I-UPF)
```
# cd go-upf
# ./upf -c upfcfg.yaml
```
free5GC 5GC U-Plane (PSA-UPF)
```
# cd go-upf
# ./upf -c upfcfg.yaml
```
Then run tcpdump on one more terminals for U-Plane.

Run tcpdump on VM2 (U-Plane (I-UPF))

# tcpdump -i upfgtp -n
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode
listening on upfgtp, link-type RAW (Raw IP), snapshot length 262144 bytes

Run tcpdump on VM3 (U-Plane (PSA-UPF))

# tcpdump -i upfgtp -n
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode
listening on upfgtp, link-type RAW (Raw IP), snapshot length 262144 bytes

Run free5GC 5GC C-Plane

Next, 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="amf udr pcf udm nssf ausf chf"

export GIN_MODE=release

./bin/nrf &
PID_LIST+=($!)
sleep 1

./bin/smf -c config/smfcfg.yaml -u config/uerouting.yaml &
PID_LIST+=($!)
sleep 1

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 UERANSIM (gNodeB)

Please refer to the following for usage of UERANSIM.

Run UERANSIM (UE)

Ping the following three destination IP addresses and confirm that they are routed through different UPFs.

google.com - routing from PSA-UPF to Internet
8.8.8.8 - routing from I-UPF to Internet
172.17.0.1 - routing from I-UPF to 172.17.0.0/16 (Docker network on local)

Note. For example, 172.17.0.0/16 is docker's default network.

Start UE connected to gNodeB
