In this test case, ABot can simulate the gNodeB and UE and any other NFs of the 5G like AMF, AUSF, SMF, UDM, UDR, NSSF, UPF.

The prerequisites for this scenario are: i) NGAP Setup is done between gNodeB/AMF and ii) UE Completed an Initial Registration procedure and PDU session procedure.

iii) UE in cm-connected state.

Now, the user profile is changed for the UE in the UDM/UDR, but UE’s current area is put under forbidden area/set to “Not allowed area”. The network initiates a Deregistration procedure due to subscriber data updates.

The procedures completed in this test case are-

• NG Setup
• Initial Registration with successfully 5G-AKA authentication procedure.
• PDU Session Establishment.
• Network initiated Deregistration for user profile change.

This test case is as per 3GPP Spec: TS 23.502, TS 24.501, TS 29.503 Rel-15.7
