A1 Policy components (subset of 'Non-RealTime RIC'):

• A1 Policy Management Service (In ONAP CCSDK/SDNC)
  
• SDNC A1 Adapter (In ONAP CCSDK/SDNC)
• Near-RT RIC / A1 Simulator (in O-RAN Source Community (OSC)) (Wiki)
  
• A1 Policy Management GUI / NONRTRIC Dashboard (in O-RAN Source Community (OSC)) (Wiki)

ONAP A1 Policy Management Service (ONAP

...

CCSDK)

The Policy Management Service is a micro service which maintains a transient repository of:

• All A1 policies instances in the network. Each policy is targeted to a near-RT-RIC instance and is owned by a 'service' (R-APP or the NONRTRIC Dashboard).
• All near-RT-RICs in the network. This information can be maintained using the ONAP CDS database (which is using the Cloudify Consul database) or using a plain text file.
• All Policy types supported by each near-RT-RIC.

The service provides :

• Unified REST API for managing A1 Policies in all near-RT-RICs.A DMaaP API for A1 Policy management (Deprecated).
• Synchronized view of A1 Policy instances for each R-APPrAPP
• 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  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

The REST API can be found at

• https://docs.onap.org/projects/onap-ccsdk-oran/en/latestlondon/offeredapis/pms-api.html

ONAP A1 Adapter (part of ONAP CCSDK/SDNC):

...

• Used to create multiple stateful A1 providers (simulated near-RT-RICs)
• Implemented as a Java Springboot application
• Swagger-based northbound interface, so easy to change the A1 profile exposed
• Supports plugable type-specific behaviors
• Please refer to the OSC A1 Simulator Documentation (Latest)
