5G Core Projects with Reference Point-Based Architecture

Hello forum members,

I’m relatively new to the world of 5G core network, so I appreciate your patience as I ask what may seem like basic questions.

I’m interested in 5G core projects that utilize a reference point-based architecture. Can anyone recommend any open-source projects that follow this approach?

In particular, I’m curious to know if the projects “free5gc” and “open5gs” implement a reference point-based architecture or if they have the capability to support it. If not, I’d appreciate any recommendations for projects that do.

Thank you in advance for your assistance.
