OPENAIR-CN-5G: An implementation of the 5G Core network by the OpenAirInterface community.

OPENAIR-CN-5G is an implementation of the 3GPP specifications for the 5G Core Network. At the moment, it contains the following network elements:

• Access and Mobility Management Function (AMF)
• Authentication Server Management Function (AUSF)
• Location Management Function (LMF)
• Network Exposure Function (NEF)
• Network Repository Function (NRF)
• Network Slicing Selection Function (NSSF)
• Network Data Analytics Function (NWDAF)
• Policy Control Function (PCF)
• Session Management Function (SMF)
• Unified Data Management (UDM)
• Unified Data Repository (UDR)
• User Plane Function (UPF) with 2 variants:
  • Simple Implementation (with a eBPF option) (UPF)
  • Legacy VPP-Based Implementation (no longer maintained) (UPF-VPP)
• Unstructured Data Storage Function (UDSF)

Each has its own repository. Some of these repositories are still private, soon to be released.

This repository is a Federation of the OpenAir CN 5G repositories.

It provides the shared Continuous Integration (CI) infrastructure used across the OpenAir Core Network 5G repositories and hosts common documentation and tutorials. See the documentation to get started.

The build status of OAI Core Network Functions is available on the OAI Jenkins dashboard.
