Deploy 5G Core with Network Slicing

Welcome to the session on 5G core deployment and network slicing. In this session, participants will set up a complete 5G network environment on Kuberenetes using automated scripts, with a special focus on deploying Open5GS and UERANSIM for core network and RAN simulation, respectively. By the end, you will have a functional 5G setup with configured network slices, providing hands-on experience with key 5G technologies.

The figure below shows our network slicing setup with 2 network slices.

Background Reading

• For a brief overview of the 5G core, see intro-to-5g-core.
• For background on network slicing, see network-slicing.
• For an overview of relevant technologies, see technologies.

1. Setting Up the Environment

In this first part of the session, you will set up the environment required to deploy a 5G core network. Automated scripts will streamline the configuration process.

• Access the Nodes: Log in to the designated nodes using the following credentials:
  • Username: user
  • Password: user
• Run the Automator Script:
  1. Kubernetes Setup: Configure a Kubernetes cluster for efficient 5G core management.
  2. Network Tools: Set up Open vSwitch (OVS) and Multus for enhanced connectivity and multi-interface support for network slicing.
  3. Configure OVS-CNI: Integrate OVS Container Network Interface (CNI) for streamlined communication within Kubernetes, supporting our network slicing framework.

By the end of this setup, participants will have a fully functional environment for 5G core deployment.

2. Deploying a 5G Core Network with Open5GS and UERANSIM

This section focuses on deploying and testing a 5G core network with network slicing:

1. Deploy a 5G Core Network: Set up two network slices.
2. Simulate a RAN and UEs: Deploy UERANSIM for RAN and user equipment simulation.
3. Subscriber Testing: Add two subscribers (one per slice) and conduct a ping test.
