Trusted Non-3GPP Gateway Function UE

Execution Flow

1. Clone the repository

git clone https://github.com/free5gc/tngfue.git
cd tngfue

2. Install prerequisites and UE configuration files

The prepare.sh script was designed to automate this process

./prepare.sh

Tip: To customize the script's execution flow, update the variables in the beginning of the file

Note: Make sure the parameters match the configuration both on free5gc database/webconsole and on Wi-Fi AP

3. Run TNGFUE

The run.sh script was designed to automate the processes required to run the UE (and to enable multiple UE executions)

./run.sh

Note: Make sure the parameters match the configuration on Wi-Fi AP and available network interface name

Additional Tips

1. For a wireless connection, keep the device's Wi-Fi interface disconnected before executing the UE
2. Use ./wpa_supplicant -h to list all available parameters
3. Some useful wpa supplicant parameters:

• -c: set configuration file
• -i: interface to listen
• -D: set driver name to be used
• -d: show debug messages
• -dd: show even more detailed debug messages

4. Debug messages can be enabled using ./run.sh -debug
5. Some other usage examples:

Note: Run the commands below inside wpa_supplicant sub-folder

• Wireless connection

sudo ./wpa_supplicant -c ../wpa_supplicant.conf -i <wifi interface name> -dd

• Wired conncetion (So far, this option has not been tested with TNGF)

sudo ./wpa_supplicant -c ../wpa_supplicant.conf -i <wired interface name> -D wired -dd
