Use Case Name

Use Case Overview & Description

O-RAN has defined A1 interface specification in the context of the management of 5G RAN elements to provide intent based policies for optimization of the RAN network performance. This requirement enhances the support for Managing and Mediating O-RAN A1 Policies in ONAP.  This extends work contributed in Rel 6 - Frankfurt ( REQ-38 - Getting issue details... STATUS ) and Rel 7 - Guilin ( REQ-352 - Getting issue details... STATUS ). A1 Adapter functionality was introduced in Frankfurt. In Guilin The A1 adapter was improved and a A1 Policy Management Service was added.

Planned enhancements for Rel 8 include: support of new A1 interface version in alignment to O-RAN alliance, common logging/audit. improved CSIT and OOM alignment, easier configuration, an improved NBI, and improved security cert management.

Business Impact: Continuing the convergence between ONAP and ORAN for A1 Policy interface to used by all service providers.

Business Markets: Enhanced A1 Policy capabilities, once developed, will be usable by any service provider deploying and using ONAP.

Funding/Financial Impacts: A1 interface provides a flexible way for the operator to manage wide area RAN network optimization, reducing capex investment needs.

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.
