Use Case Name
Use Case Overview & Description
This requirement enhances the A1 interface capabilities provided in Rel 6 as part of 5G/ORAN & 3GPP Standards Harmonization requirement ( REQ-38) and extended in Rel 7 with the introduction of A1 policy management. 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 (
) and Rel 7 - Guilin (Jira server ONAP JIRA columns key,summary,type,created,updated,due,assignee,reporter,priority,status,resolution serverId 425b2b0a-557c-3c0c-b515-579789cceedb key REQ-38
). A1 Adapter functionality was introduced in Frankfurt. In Guilin The A1 adapter was improved and a A1 Policy Management Service was added. Jira server ONAP JIRA serverId 425b2b0a-557c-3c0c-b515-579789cceedb key REQ-352
Planned enhancements for Rel 8 include: support of new A1 interface version in alignment to O-RAN alliance and , common logging/audit. improved CSIT and OOM alignment, easier configuration, an improved NBI, and improved security cert management.

Planned enhancements for Rel 8 include: support of new A1 interface version in alignment to O-RAN alliance and , common logging/audit. improved CSIT and OOM alignment, easier configuration, an improved NBI, and improved security cert management.
Business Impact: Continuing the convergency convergence between ONAP and ORAN for A1 Policy interface to used by all service providers and avoid duplicate development efforts.
Business Markets: Enhanced A1 Policy capabilities, once developed, will be useable usable by any service provider deploying and using ONAP.
...
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.
