1. Install the required packages

   • sudo apt -y update
   • sudo apt -y install mongodb wget git
   • sudo systemctl start mongodb

2. Go installation

   • If another version of Go is installed
     • Please remove the previous Go version
       • sudo rm -rf /usr/local/go
     • Install Go 1.12.9
       • wget https://dl.google.com/go/go1.12.9.linux-amd64.tar.gz
       • sudo tar -C /usr/local -zxvf go1.12.9.linux-amd64.tar.gz
   • Clean installation
     • Install Go 1.12.9
       • wget https://dl.google.com/go/go1.12.9.linux-amd64.tar.gz
       • sudo tar -C /usr/local -zxvf go1.12.9.linux-amd64.tar.gz
       • mkdir -p ~/go/{bin,pkg,src}
       • echo 'export GOPATH=$HOME/go' >> ~/.bashrc
       • echo 'export GOROOT=/usr/local/go' >> ~/.bashrc
       • echo 'export PATH=$PATH:$GOPATH/bin:$GOROOT/bin' >> ~/.bashrc
       • echo 'export GO111MODULE=off' >> ~/.bashrc
       • source ~/.bashrc

3. Clone free5GC project in $GOPATH/src

   • cd $GOPATH/src
   • git clone https://bitbucket.org/free5GC/free5gc-stage-2.git free5gc

4. Run the script to install dependent packages

   • cd $GOPATH/src/free5gc

   • chmod +x ./install_env.sh

   • ./install_env.sh

   • Please ignore error messages during the package dependencies installation process.

5. Extract the free5gc_libs.tar.gz to setup the environment for compiling

   • cd $GOPATH/src/free5gc
   • tar -C $GOPATH -zxvf free5gc_libs.tar.gz

6. Compile network function services in $GOPATH/src/free5gc, e.g. AMF:

   • cd $GOPATH/src/free5gc
   • go build -o bin/amf -x src/amf/amf.go

7. Run network function services, e.g. AMF:

   • cd $GOPATH/src/free5gc

   • ./bin/amf

   • In step 3, the folder name should remain free5gc. Please do not modify it or the compilation would fail.

1. Install the required packages

   sudo apt -y update
   sudo apt -y install git gcc cmake autoconf libtool pkg-config libmnl-dev libyaml-dev
   go get -u github.com/sirupsen/logrus

2. Enter the UPF directory
   • cd $GOPATH/src/free5gc/src/upf
3. Build from sources
   • mkdir build
   • cd build
   • cmake ..
   • make -j `nproc`
4. Run UPF library test
   • (In directory: $GOPATH/src/free5gc/src/upf/build)
   • sudo ./bin/testgtpv1
5. Config is located at $GOPATH/src/free5gc/src/upf/build/config/upfcfg.yaml

Start Wireshark to capture any interface with pfcp||icmp||gtp filter and run the tests below to simulate the procedures:

cd $GOPATH/src/free5gc
chmod +x ./test.sh

a. TestRegistration

(In directory: $GOPATH/src/free5gc)
sudo ./test.sh TestRegistration

b. TestServiceRequest

sudo ./test.sh TestServiceRequest

c. TestXnHandover

sudo ./test.sh TestXnHandover

d. TestDeregistration

sudo ./test.sh TestDeregistration

e. TestPDUSessionReleaseRequest

sudo ./test.sh TestPDUSessionReleaseRequest

The below commands may be helpful for development purposes.

1. Remove POSIX message queues
   • ls /dev/mqueue/
   • rm /dev/mqueue/*
2. Remove gtp tunnels (using tools in libgtpnl)
   • cd ./src/upf/lib/libgtpnl-1.2.1/tools
   • ./gtp-tunnel list
3. Remove gtp devices (using tools in libgtpnl)
   • cd ./src/upf/lib/libgtpnl-1.2.1/tools
   • sudo ./gtp-link del {Dev-Name}

Install packages:

sudo apt-get install pcscd pcsc-tools libccid python-dev swig python-setuptools python-pip libpcsclite-dev
sudo pip install pycrypto

Download PySIM

git clone git://git.osmocom.org/pysim.git

Change to pyscard folder and install

cd <pyscard-path>
sudo /usr/bin/python setup.py build_ext install

Verify your reader is ready

sudo pcsc_scan

Check whether your reader can read the SIM card

cd <pysim-path>
./pySim-read.py –p 0

Program your SIM card information

./pySim-prog.py -p 0 -x 208 -y 93 -t sysmoUSIM-SJS1 -i 208930000000003 --op=8e27b6af0e692e750f32667a3b14605d -k 8baf473f2f8fd09487cccbd7097c6862 -s 8988211000000088313 -a 23605945

You can get your SIM card from sysmocom. You also need a card reader to write your SIM card. You can get a card reader from here or use other similar devices.
