This sequence diagram shows the NSMF and NSSMF interactions for RAN Slicing Option 1, and when all NSSMFs are within ONAP.

Assumptions:

  • RAN Option 1 or Option 2 shall be determined by NSMF by examining the NST contents.
  • NSMF shall determine if it has to do NSSI selection (in case of external NSSMF) for a domain by checking the vendor in the NSST.

1. NSI Instantiation


This sequence diagram shows the NSMF and NSSMF interactions for RAN Slicing Option 2, and when RAN and Core NSSMFs are outside ONAP.
