This document explains how to install and configure OAI EPC+eNB on one single Ubuntu 18.04 64 bits machine connected with a regular UE, routing the UE traffic to internet.


The description uses a USRP B210 board.
Kita akan men-test dengan commit: 724542d0b59797b010af8c5df15af7f669c1e838


We also explain how to simplify, fix existing issues, to make a single computer as a full LTE network: EPC+eNB.

Useless link between OAI and the Ubuntu/Linux hostname removed
Several simplifications and precisions to make easier and reliable installations
Install Ubuntu
Prepare a machine: a 4 actual cores, no hyper-threading.
All other configuration in OAI Wiki (C1 states, …) describes is about useless.
Download Ubuntu 18.04 64 bits version iso file
create a usb key to boot on it
install Ubuntu: choose to install Third party SW, and to upgrade all packages while installing
do: apt update; apt upgrade until the machine is up-to-date
install git and configure your identification in git:
sudo apt install git
git config --global user.name "Laurent"
git config --global user.email "laurent.thomas@open-cells.com"
Add the OAI repository as authorized remote system
echo -n | openssl s_client -showcerts -connect gitlab.eurecom.fr:443 2>/dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' | sudo tee -a /etc/ssl/certs/ca-certificates.crt
if you are upset with sudo password, add this line in /etc/sudoers
xxxxxx ALL=(ALL) NOPASSWD: ALL (xxxxxx is your login name)
sudo will not ask anymore for a password
Install USRP drivers
We prefer to use UHD driver from source:


sudo apt-get install libboost-all-dev libusb-1.0-0-dev python-mako doxygen python-docutils python-requests python3-pip cmake build-essential
tar xf openair-cn.tgz
pip3 install mako numpy

This is the last commit for OAI EPC on this development tree. Active OpenAir EPC is now another project on github. We use here this legacy EPC because the installation is quite easy (the new project uses Cassandra, al LOT of virtual machines, OpenVswitch and complex dependancies).


Apply the patch:
cd openair-cn; source oaienv; cd scripts
./build_hss -i


git apply ~/opencells-mods/EPC.patch
* Jawab yes untuk install: freeDiameter 1.2.0
The new version of the source files are also in the tar, if you want to merge with another version of OpenAir EPC
* phpmyadmin:
** Kita tidak menggunakan phpmyadmin nanti dalam prosedur ini untuk memperbarui database MySQL
** Kita menghapus instalasi phpmyadmin (tentu saja kita dapat menggunakannya jika kita mau)


What is in the patch file:
Untuk ubuntu 18.04, kami mengatur kembali tingkat keamanan mysql


Add Ubuntu 18.04 for compilation and fix some bugs
sudo mysql -u root << END
Remove link between Linux host name and LTE diameter protocol configuration
USE mysql;
Add usage of the input address for the SGW input socket
UPDATE user SET plugin='mysql_native_password' WHERE User='root';
modify the freediameter S6a interface to fix a wrong OAI parameter
FLUSH PRIVILEGES;
No kernel module patch is required: generic Ubuntu kernel 18.04 works fine with OAI
END
separate ASN.1 compiler installation to be compatible with other OpenAir components on the same machine (ans1c version is different for eNB and gNB)
Install third party SW for EPC
cd openair-cn; source oaienv; cd scripts
./build_hss -i
Answer yes to install: freeDiameter 1.2.0
phpmyadmin:
We don’t use phpmyadmin later in this procedure to update the MySQL database
We removed the installation of phpmyadmin (of course you can use it if you prefer)
For ubuntu 18.04, we set back the legacy mysql security level


sudo mysql -u root << END
sudo systemctl restart mysql.service
USE mysql;
sudo mysql_secure_installation
UPDATE user SET plugin='mysql_native_password' WHERE User='root';
FLUSH PRIVILEGES;
END


sudo systemctl restart mysql.service
Perintah terakhir akan menanyakan beberapa pertanyaan:


sudo mysql_secure_installation
password: set your password (linux is set in our default config files)
The last command will ask a few questions:
VALIDATE PASSWORD PLUGIN: no
Remove anonymous users: yes
Disallow root login remotely: yes
Remove test database and access to it: yes
Reload privilege tables now: yes

Download dan ekstrak data-nya, 

cd ~
wget https://open-cells.com/opencells-mods-20190923.tgz

Download dan patch EPC

Clone OAI EPC: 

# maybe go back to home directory (leave openairinterface5g directory)
git clone https://gitlab.eurecom.fr/oai/openair-cn.git
cd openair-cn
git checkout develop

Kita akan men-test dengan commit: 724542d0b59797b010af8c5df15af7f669c1e838

openair-cn

ekstrak tar dengan 

tar xf openair-cn.tgz
cd openair-cn
git checkout develop

Ini adalah komitmen terakhir untuk OAI EPC pada development tree ini. Active OpenAir EPC sekarang menjadi proyek lain di github. Di sini kita menggunakan EPC lawas ini karena pemasangannya cukup mudah (proyek baru menggunakan Cassandra, BANYAK mesin virtual, OpenVswitch, dan ketergantungan yang lebih kompleks).

Apply patch: 

git apply ~/opencells-mods/EPC.patch

Versi baru source file juga ada di tar, jika kita ingin menggabungkan dengan versi lain dari OpenAir EPC

Apa yang ada di patch file adalah:

  • Tambahkan Ubuntu 18.04 untuk kompilasi dan perbaiki beberapa bug
  • Hapus link antara host name Linux dan konfigurasi protokol diameter LTE
  • Tambahkan penggunaan alamat input untuk soket input SGW
  • memodifikasi interface S6a freediameter untuk memperbaiki parameter OAI yang salah
  • Tidak diperlukan tambalan modul kernel: kernel generik Ubuntu 18.04 berfungsi baik dengan OAI

pisahkan instalasi kompiler ASN.1 agar kompatibel dengan komponen OpenAir lainnya pada mesin yang sama (versi ans1c berbeda untuk eNB dan gNB)

Install third party SW untuk EPC

cd openair-cn; source oaienv; cd scripts
./build_hss -i
  • Jawab yes untuk install: freeDiameter 1.2.0

Do you want to install asn1c rev 1516 patched? <y/N>: yes
Do you want to install libgtpnl ? <y/N>: yes

Compile EPC node

Tidak ada kesulitan yang ditemukan pada fase ini. 

cd openair-cn; source oaienv; cd scripts

Jika kita menghadapi masalah kompilasi, file log ada di openair-cn/build/log

Di file tersebut, cari "error:" string.
