Description
Description of Use Case / Requirement:
This feature requirement enhances A1 Policy Management for the O-RAN A1 interface capabilities provided in Rel 6, 7, 8, 9, 10. 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 11 include support of new A1 interface versions to align with new versions & improvements to O-RAN alliance specifications.

Dependency Relationships with Other Projects:
CCSDK
- A1 Policy Management Service and A1 Adapter are homed in CCSDK
- Impact Type: C (Code)
- Company Engagement: Ericsson
- Resources: Ericsson team & others
- Support Status: S (Supported)
- Non-Functional Requirement Support: tbc
SDNC (No change in Kohn)
- A1 Adapter is deployed as part of SDNC
- A1 Policy Management Service is a standalone micro-service deployed with SDNC
- Impact Type: none
- Company Engagement: Ericsson
- Resources: Ericsson team & others
- Support Status: S (Supported)
- Non-Functional Requirement Support: tbc
Interfaces / APIs:
• Northbound Interface
- As before (Istanbul)
- A1-PMS v2 NBI (REST & DMaaP) has existed since Honolulu
- It is hoped that O-RAN Alliance will continue to specify the O-RAN R1 interface - which should expose a service for Non-RT-RIC interactions for A1 Policies.
- A1-PMS NBI will evolve (backward compatible) to support this R1 Service once defined - perhaps during the lifetime of this REQ.
• Southbound Interfaces
- As before (Istanbul)
- OSC A1 v2.1 (Existing)
- O-RAN A1 v1.1 (Existing)
- O-RAN A1 v2.0 (Existing)
- O-RAN A1 v3+ (Small changes from v2.0)
- If changes are approved by O-RAN Alliance during this lifetime of this REQ.
- Add support for custom connector plug-ins to easily support new A1 connection profiles
• Internal Interface (A1 Policy Management Service <-> 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.
