Description | This use case will lay the groundwork to introduce and open the discussion with the modeling sub-committee for the platform information modeling work to allow ONAP to integrate with a real "live" 5G DU Base station (PNF) The RAN (wireless) 5G base station network resource model is driven by the 3GPP standard: TS28.540 and TS28.541, the 5G NRM. This standard is used by all 5G vendors for their PNFs (DUs) which serves as a starting point to think about modeling work as it is common to all vendors. ONAP will not necessarily need to know or work with all of the ~300 parameters described in the standard, but rather should introduce a common "core" model into the ONAP platform release information model, so that other future use cases and applications can introduce model information in an orderly fashion. In R7, the OOF/SON/PCI and End-to-End Network Slicing use cases will leverage the work to introduce this common "core" model. Note that, these use cases ARE domain specific, to network wireless / radio access networks. So some thought should be given as to how to introduce domain-specific modeling into ONAP such that it can still serve many other domains with full functionality given to each of those domains. | |
