In this test case, ABot can simulate the gNodeB and UE and any other NFs of the 5G like AMF, AUSF, UDM, UDR, NSSF, UPF1, UPF2.

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, UE initiated PDU session Termination triggered. SMF sends policy deletion to PCF with usage monitoring report and PCF sends it to UDR. Aslo SMF initiates PFCP session deletion procedure.

The procedures completed in this test case are-

• NG Setup
• Initial Registration with successfully 5G-AKA authentication procedure.
• PDU Session Establishment.
• PFCP session deletion

This test case is as per 3GPP Spec: TS 23.502, TS 29.513 Rel-15.7
