Functional Architecture
Enhancements for Istanbul Release
- O-RAN Alliance A1 Specification evolution (A1-AP & A1-TP)
- A1 Policy State Management & Persistent Storage in A1 Policy Management Service
- Support failover, restart, etc.
- HTTP/HTTPS proxy support in A1 Adapter (A1 Southbound only)
- Improved A1-REST response code transit through A1 Adapter
- Support updated RESTCONF spec (RFC 8040 - used in ODL) between A1 Policy Management Service & A1 Adapter
- RFC 8040 : https://tools.ietf.org/html/rfc8040
- Older RESTCONF (https://tools.ietf.org/html/draft-bierman-netconf-restconf-02) being phased out.
- Re-align OOM configuration for near-RT-RICs in A1 Policy Management Service config
- Add more fine-grained near-RT-RIC in A1 Policy Management Service REST runtime config interface
- Improved documentation & testing
- A1 Policy Management participant for use in ONAP Control Loops (Stretch – TBC)
- Support A1 Policy operations in SON usecases (RAN Slicing & PCI – TBC) (Stretch – TBC)

Use Case Title | |
Actors (and System Components) | SDNC / CCSDK - A1 Adapter & A1 Policy Management Service |
Description | This feature requirement enhances A1 Policy Management for the O-RAN A1 interface capabilities provided in Rel 6, 7 & 8. Work will continue by extending & evolving support for using A1 Policies to manage 5G RAN elements by providing intent based policies for optimization of the RAN network performance. Planned enhancements for Rel 9 include support of new A1 interface versions to align with new versions & improvements to O-RAN alliance specifications. |
