Allocation of IP Address to UI during PDU session establishment

Hello Guys,

Thanks for sharing this project and really appreciate all your assistance.
During testing registration use case, I could see ip allocation for UI in SMF, but could not find ip address allocation to UI in N1/N2.

afaik it should happen through PDU session establishment.
Should Free5Gc support this use case? is it encrypted in NSA messages, so I could not find it in wireshark?
Thanks a lot,

What do you means for the “UI”?

Sorry, my typo, should be UE (User Equipment)


Yes, SMF will allocate a IP for UE and send it through UE via passing AMF and RAN. If will be encrypted, or not encrypted if you choice plain text, by NAS message.
