In this test case, ABot can simulate the NRF, AMF, SMF1, SMF2.

5GS NRF Dynamic Subscription by AMF for Registration event of NF Type SMF with NRF Registration of 
SMF1 and SMF2 and respective NRF Notification to AMF.

The procedures completed in this test case are-

• AMF 1 registers to NRF
• AMF1 subscribes for nf type SMF registration event
• SMF1 registers to NRF
• NRF sends a notification for SMF1 to AMF
• SMF2 registers in NRF
• NRF sends a notification for SMF2 to AMF & NRF sends a notification for SMF1 to AMF

This test case is as per 3GPP Spec: TS 23.502, TS 24.501, TS 29.510 Rel-15.7
