Business Driver
EXECUTIVE SUMMARY - This requirement enhances the A1 adapter/interface capabilities provided in Rel 6 as part of 5G/ORAN & 3GPP Standards Harmonization requirement ( REQ-38). 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. Planned enhancements for Rel 7 include additional support for managing A1 Policies, multiple A1 targets in the RAN, multi-version support for different A1 targets, and secure TLS communication.

- Guilin: None required – Studies only
- Stretch Goal: “Hello world” demonstrations with other ONAP components
- Honolulu: A&AI, RuntimeDBConfiguration & Persistency Service, DCAE, CLAMP, Policy. (TBC)
- Will form part of cross-project 5G integration use cases envisioned for Honolulu (TBC)
...
- Update Documentation with A1 interface aspects
- Update Integration & Existing Test requirements
Testing
Test use-cases:
- Synchronize A1 Policy Information in RAN
- A1 Policy Type / Instance Operations
- A1 Policy Instance Status Operations
- See REQ-447 and linked resources for more information on TEST Release Requirements
Test variations:
- A1 Adapter with/without A1 Policy Management Service
- A1 versions:
- O-RAN Alliance (spec) v1.1.3
- O-RAN-SC A1 (non-spec) v2.1.0
