Free5GC orchestration using ONAP EMCO

We have onboarded Free5GC CNFs onto ONAP EMCO and then orchestrated them onto Kubernetes K8s (https://youtu.be/kIMgVwIDwr4). We are now going to do some testing with a commercial UE/gNB emulator. If anybody is interested in collaborating, please let me know.

Hi,

That’s sounds interesting!

If there is anything needed to be modify on free5GC either on config or on NF manager to make it easier to be used, please let us know!

Hello,
We are facing an error while integrating the gNB emulator with the free5G.
UE registration request to AMF is failing for us. Can you please give us some pointers?
The log that we see in the AMF is,

Sandeep,

I’ve done something similar myself, also having built both 5GMANO and 5GC running in k8s.

I’d be more than happy to collaborate

Donal

Donal,
Please send emai to info@aarnanetworks.com to further discuss the collaboration.
Thanks
