Documentation
- The source code is available in: ONAP CCSDK (O-RAN) Gerrit repo ('montreal' branch)
- Support functions available in OSC repos: OSC A1-Simulator (Gerrit) & OSC NONRTRIC Control Panel (Gerrit)
- The Official Documentation can be found at https://docs.onap.org/projects/onap-ccsdk-oran/en/montreal/
- Additional Non-RealTime RIC functions are developed in the OSC NONRTRIC project - which reuses these A1 Policy components.

ONAP A1 Policy Management Service (ONAP
...
CCSDK)
The Policy Management Service is a micro service which maintains a transient repository of:
...
- Unified REST API for managing A1 Policies in all near-RT-RICs.
- Synchronized view of A1 Policy instances for each rAPPrApp/Client
- Synchronized view of A1 Policy instances in each near-RT-RIC
- Synchronized view of A1 Policy types supported by each near-RT-RIC
- Lookup service to find the near-RT-RIC to control resources in the RAN as defined in O1 (e.g. which near-RT-RIC should be accessed to control a certain CU or DU, which in turn controls a certain cell).
- Monitors all near-RT-RICs and maintains data consistency – e.g. recovery from near-RT-RIC restarts
- Support for different Southbound APIs APIs to the near-RT-RICs (different versions of the A1-P and other similar APIs).
- HTTPS can be configured to use a supplied certificate/private key and to validate peers towards a list of trusted CAs/certs.
- HTTP proxy support for tunneling HTTP/HTTPS connections.
- Fine-grained access-control - with new optional callouts to an external auth function
