Enhancements for Honolulu Release
- Add support for O-RAN Alliance A1-AP v2.0 1 specification (A1 Policy only)
- Improve alignment with OOM deployment & configuration options
- Improve alignment with CSIT way of working for function tests
- New REST interface for configuration
- New A1 Policy Management NBI (REST & DMaaP)
- Improved security cert management
- Stretch: Investigate if A1 Policy manipulation can be incorporated into other use cases (e.g. Slicing, OOF) - TBC
A1 Policies - Northbound Interface (REST & DMaaP) Proposed
- Changes proposed for A1 Policy Management Service NBI (not-backward compatible)
- Coming Soon!
Use Case Functional Definitions

Other Impacts
Affected ONAP Functions:
...
Interfaces:
- Northbound Interface – See earlier section
- Add/Change SDNC CCSDK A1 Policy Management Service NBI for A1 Policy Management (REST & DMaaP)
- The new version of the PMS REST API complies with the ONAP REST API and Zalando style guidelines and fixes some naming inconsistencies.
- REST (New version)
- DMaaP (New version)
- Ref: CCSDK-3077
- Configuration

- O-RAN A1 v1.1 (Existing)
- O-RAN A1 v2.0 1 (New)
Usage outside ONAP:
- Used in O-RAN-SC NONRTRIC Project (Downstream)
- Southbound Interface: O-RAN A1 Interface + Information Model is specified and maintained by O-RAN Alliance
...
- Update Documentation with A1 interface aspects
- Update Integration & Existing Test requirements
Testing
Test use-cases:

Use Case Functional Definitions
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. |
