Installation and deployment of 5G Core (5GC) of Open Air Interface (OAI)

Objectives

  • Install and configure the 5GC of OAI in a virtual machine Ubuntu 20.04 LTS (Focal Fossa)
  • Deploy 5GC Core
  • Inspec 5G Core Docker containers by means of command line instructions
  • Install and configure Portainer tool
  • Inspec 5G Core Docker containers by means of Portainer browser

Minimum hardware requirements for OAI UE, according to doc/NR_SA_Tutorial_COTS_UE.md · develop · oai / openairinterface5G · GitLab (eurecom.fr):

  • Ubuntu 20.04.5 LTS;
  • CPU: 4 cores x86_64;
  • 8 GB RAM.

Minimum hardware requirements for OAI 5GC and OAI gNB, according to doc/NR_SA_Tutorial_COTS_UE.md · develop · oai / openairinterface5G · GitLab (eurecom.fr):

  • Ubuntu 20.04.5 LTS;
  • CPU: 8 cores x86_64 3.5 GHz;
  • 32 GB RAM.

However, if you do not have such hardware specifications, you may use the one below for both devices (tested for us, you may face some lags, but it works):

  • Ubuntu 20.04.5 LTS;
  • CPU: 4 cores x86_64;
  • 4 GB RAM.

5GC Installation

In a Linux Terminal, follow the steps below:

Step 0: Setup your VM or Baremetal Machine, after install Useful Software:

sudo su

apt update -y

Step 1: Install dependencies

sudo apt-get install ca-certificates

sudo apt-get install curl

sudo apt-get install gnupg

sudo apt-get install lsb-release

Step 2: Enable packet forwarding

sudo sysctl net.ipv4.conf.all.forwarding=1

sudo iptables -P FORWARD ACCEPT

Step 3: Install docker and docker-compose

sudo rm /etc/apt/sources.list.d/docker.list*

sudo mkdir -p /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
