The Open Core Network (OCN) Project Group

is focused on developing an open, cloud-native, and converged core, running on standardized software and hardware infrastructure, and supporting 4G, 5G, and Wi-Fi access technologies for deployments in licensed, unlicensed, or shared spectrum.

The Open Core Network group is working to develop an open, cloud-native, and converged core that is a collection of microservices implementing various core network functions (“open, flexible and extensible”):

  • Running on standardized software and hardware infrastructure (“infrastructure agnostic”)
  • Supporting 3GPP 5G Core (5GC) and LTE Evolved Packet Core (EPC) for licensed, unlicensed (e.g. Wi-Fi), and shared spectrum (e.g., CBRS) networks (“access agnostic”)
  • Enabling seamless migration from 4G EPC to 5GC in both Non Stand-Alone (NSA) and Stand-Alone (SA) modes

The goal is to innovate on the packet core technologies across any access wireless networks operating on licensed, unlicensed and shared spectrum; develop microservice, orchestration and automation frameworks on OCN platform, and support an ecosystem of developers, OEMs, SIs, MNOs, and ISPs around OCN based solutions.

Join the Open Core Network Project Group to collaborate with Mobile Operators, Service Providers, Technology Providers, System Integrators, Research Institutes, and Industry Associations in conceiving new ways of building, testing and deploying core network infrastructure.

The Open Core Network project group activities are currently sub-divided in three parallel work-streams:

Applications and Services

Led By:

Phillip Ritter (Facebook)

Veronica Quintuna Rodriguez (Orange)

The goal of this work-stream is to design, develop and deliver a set of production-grade microservices implementing 3GPP 4G/LTE, 5G, shared spectrum (e.g., CBRS) and Wi-Fi core network functions and APIs between such functions as well as between these functions and RAN elements or Network Management Systems.


Led By:

Iain Wilkinson (Vodafone)

Alla Goldner (Amdocs)

The goal of this work-stream is to design, develop and deliver an orchestration framework for integrating, deploying and managing OCN microservices, including FCAPS, metrics, analytics and monitoring.


Led By:

Boris Renski (FreedomFi)

The goal of this work-stream is to design, develop and deliver an infrastructure and test automation, i.e., CI/CD framework for testing OCN microservices.
