BUSINESS DRIVER
This section describes Business Drivers needs. These business drivers are presented on the Requirements Sub-committee and should also be put into the release requirements sub-committee page.
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.
Business Markets - This project applies to any domain (wireless, transport, optical, and wireline) that ONAP may manage..
Funding/Financial Impacts - Without the groundwork laid down for information model management of a 5G Service, operators will not be able to "turn on" a real live 5G network using "live" PNF resources. No Network. No Business. High OPEX impact.
Organization Mgmt, Sales Strategies - There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider.

USE CASE DIAGRAM
Use cases define how different users interact with a system under design. Each use case represents an action that may be performed by a user (defined in UML as an Actor with a user persona).
