Extend ORAN A1 Adapter and add A1 Policy Management - Guilin

Description

Description of Use Case / Requirement:

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.
