Use Case Title | |
Actors (and System Components) | SDNC / CCSDK - A1 Adapter & A1 Policy Management Service |
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) and Rel 7 - Guilin (REQ-352). 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. |
