5gc

The 5gc repository builds a standalone Aether core with a physical RAN setup. It depends a k8 cluster which can be deployed using k8 repository that can help to create a multi-node cluster.

To set up the 5gc repository, you need to provide the following:

  1. Node configurations with IP addresses in the host.ini file.
    • You can specify both master and worker nodes.
  2. Aether configuration parameters, such as RAN_Interface, in the ./var/main.yaml file.

To download the 5gc repository, use the following command:

git clone https://gitlab.com/onf-internship/5gc.git
git clone https://gitlab.com/onf-internship/k8s.git

Step-by-Step Installation

To install the 5g-core, follow these steps:

  1. Set the configuration variables in the vars/main.yaml file.
    • Set the "standalone" parameter to deploy the core independently from roc.
    • Specify the "data_iface" parameter as the network interface name of the machine.
    • Set the "values_file" parameter:
      • Use "sdcore-5g-values.yaml" for a stateful 5g core.
      • Use "hpa-5g-values.yaml" for a stateless 5g core.
    • The "custom_ran_subnet" parameter if left empty, core will use the subnet of "data_iface" for UPF.
  2. Add the hosts to the init file.
  3. Run make ansible.
  4. In the running Ansible docker terminal:
    • Make sure you have dployed a k8 cluster using k8s-install from k8s repo.
    • run make 5gc-install
    • It creates networking interfaces for UPF, such as access/core, using 5gc-router-install.
    • Finally, it installs the 5g core using the values specified in 5gc-core-install.
      • The installation process may take up to 3 minutes.

One-Step Installation

To install 5gc in one go, run make 5gc-install.

Uninstall

  • run make 5gc-uninstall
