EXECUTIVE SUMMARY - This requirement introduces platform information model enhancements to document new ISOMII experimental classes from 3GPP TS28.541, the 5G Network Resource Model (NRM). The purpose of this use case is to introduce the necessary changes into the ONAP platform architecture so that it can be prepared to accept and work with a real live 5G RAN DU (for a gNB). Presently, this may mean introducing a generic application model defined in CDS. This model would then integrate the 3GPP 5G NRM so that ONAP components and micro-services could access the information in a 3GPP format without needing to overhaul the Platform Information Model.
BUSINESS IMPACT - The requirement, is a critical because it will serve to lay the ground-work for actually "turning on" a real 5G DU (PNF) that might be installed by a Vendor.

Attributes | Attributes: Name and describe each attribute of this Information Element. Please include the datatype of the attribute if possible. Is this attribute read-only, read-write? Are there any default values? | Relationships | Relationships: Describe how this Information Element is related to other Information Elements. Also describe nature of the relationship: association, inheritance, dependency, etc. and multiplicity There are hundreds of parameters in the 5G NRM from the above standards. A spreadsheet of all of the parameters are compiled in this spreadsheet:

Relationships | RUN TIME - (SO, CDS, PRH). PNFs that need to be instantiated in 5G Services (associated resources for a service). RUN TIME - (OOF SON PCI Use Case) - The PCI Micro-service will need the PCI values in the 5G NRM. | ||||||||||||||||||||
Originator | Where does this information come from? (What component initially creates it) | ||||||||||||||||||||
| Consumers | Who uses this information inside & outside of ONAP? How do they use it? Includes description of information consumed (whole class, specific attributes, etc.) | ||||||||||||||||||||
Producers | Who updates this information inside & outside of ONAP? A user would load the Generic Application Model. CDS would update this information inside of ONAP. A user would specify a domain specific model to use. Under what conditions do they update it? Includes In design time, if the designer determined that a resource will be using the Generic Application Model, they can choose to update it with a domain specific model. The detailed description of information produced (whole classclasses, specific attributes, etc.)attributes) can be obtained in the 3GPP TS28.541 standards that can be retrieved from the links above. | ||||||||||||||||||||
Steward | Where will this information stored and maintained in ONAP? ? This model information would become a part of the CDS repository. During design time, CDS would be used to load a domain specific model | ||||||||||||||||||||
| Impacted APIs & SchemasIdentify | With the Generic Application Model Solution, CDS Platform component will need to be updated and its APIs may be impacted. CDS would load the Generic Application Model and populate it with a standard defined model, for example, the 3GPP 5G NRM. CDS would have an impacted ONAP schemas & APIsAre there existing schemas be used or extended?API updated | ||||||||||||||||||||
