N2 Handover

In this test case, ABot can simulate the gNodeB1, gNodeB2 and UE and any other NFs of the 5G like AMF, AUSF, UDM, UDR, NSSF. Initial condition of the scenario is: NGAP Setup done between source gNodeB/AMF and target gNodeB/AMF. The UE Completed an Initial Registration procedure via source gNodeB/AMF. PDU session establishment done for UE.

Now, N2 Handover takes place Source gNodeB (gNodeB1) to target gNodeB (gNodeB2) via AMF1.

The procedures completed in this test case are-

  • NG Setup gNodeB1 to AMF1 and gNodeB2 to AMF1.
  • Initial Registration with successfully 5G-AKA authentication procedure.
  • PDU Session Establishment
  • N2 Handover from Source gNodeB (gNodeB1) to target gNodeB (gNodeB2) via AMF1.


This test case is as per 3GPP TS 36.300, 3GPP TS 38.300, 3GPP TS 23.502, 3GPP TS 23.501
