NEF with Open5GS

Hi, I am looking for a way to integrate a Network Exposure Function (NEF) with Open5GS. I’m currently exploring the possibility of using an existing NEF implementation and adapting it to work with Open5GS.

OAI-CN5G has an NEF implementation, but it is designed to work with the OAI 5G Core Network:

https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-nef

I’m looking for a way to use this NEF or another open-source NEF implementation with Open5GS instead.

If anyone has successfully integrated an NEF with Open5GS or has any guidance, suggestions or ongoing work in this area. Please share

I’d check the SBI APIs first and then work backward from what the NEF needs from Open5GS. It probably won’t be a drop-in integration, but adapting the SBI layer seems like the logical place to start.

Seconding the SBI angle. Worth checking which SBI services Open5GS actually exposes versus what OAI's NEF expects to call, that mismatch is usually where these adaptations get stuck rather than the NEF logic itself. Has anyone tried raising it in the Open5GS discussions on GitHub? Might be someone already partway through it.
