Supported behavior
Know the current baseline before depending on the core for a broader 5G workflow.
Default SA path
The current core targets a narrow but real 5G SA lab path: registration, authentication, slice selection, PDU-session establishment, SMF-to-UPF session programming, and N3 user-plane handling.
| Area | Current baseline |
|---|---|
| Subscriber/auth | Lab subscriber authentication through AUSF, UDM, and UDR. |
| Slice/policy | Single default slice and DNN policy through NSSF and PCF. |
| Session | Default PDU session flow through AMF and SMF. |
| User plane | UPF N3 GTP-U handling for the supported lab tunnel. |
| Interop target | UERANSIM-centered lab behavior; broad hardware compatibility is not claimed. |
