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.

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. |
