BUSINESS DRIVER
This section describes Business Drivers needs.
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).
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).
USE CASE FUNCTIONAL DEFINITIONS
Use Case Title | 5G Service Modling |
Actors (and System Components) | N/A, Modeling work |
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. |
