EXECUTIVE SUMMARY
-This contribution introduces a new domain in VES, stndDefined, which indicates that the event contains data that conforms to format/schema defined by a separate standards organization. In addition we propose one new field in the VES Common Header to enable further classification of such events, e g to support routing of these events to appropriate DMaaP topics. An optional second stage validation is proposed in DCAE prior to acknowledging the event to enhance trouble shooting.
-It is proposed that the first application of this generic capability supports VES encapsulated 3GPP defined notifications as described in 28.532 version 16.3.0 Annex B (informative). The ORAN O1 specification also refers to VES-based 3GPP notifications for several management services, and in those cases is expected to further align with the approach and solution published in 3GPP in a future release.
BUSINESS IMPACT- The ability for service providers to deploy ONAP as the SMO in their O-RAN compliant network depends upon ONAP’s ability to process VES encapsulated events as defined by 3GPP and ORAN in DCAE and route these events to appropriate DMaaP topics. This proposal, in Guilin, provides the necessary capability for ONAP to process and validate events that are defined using 3GPP schema for the data. The proposal is readily extensible for the support of additional events from 3GPP, ORAN or other standards organizations adding a high degree of flexibility to the ONAP platform.
BUSINESS MARKETS- This contribution applies to any Service Provider that wants to use ONAP as an O-RAN compliant SMO or to support 3GPP compliant interfaces and can be leveraged by Service Providers wishing to support events from network functions which are aligned with other standards organizations.
FUNDING/FINANCIAL IMPACTS- This contribution helps enable ONAP to be O-RAN and 3GPP compliant which should stimulate contributions from companies that are aligned with O-RAN and 3GPP. There is no new hardware to be procured and no new licenses.
ORGANIZATION MGMT, SALES STRATEGIES- This proposal does not affect sales strategies.

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).
