 The CCSDK ORAN components add support for handling "A1 Policies" as defined for the O-RAN A1-P interface.

-The A1 Policy Management Service provides an API for accessing of A1 Policies. The PMS
-configures these in the traffical elements (NearRT-RICS). It also keeps a backup of these in case of restart of PMS.
-On regular basis, it will check that the configured A1 Policices are consistent with the actual ones in the NearRT-RICS (and take action if not).
- 
-The access to the NearRT-RIC may be tunneled through an A1 adapter in the CCSDK/SDNC controller.
+The A1 Policy Management Service (A1-PMS) provides an API for accessing A1 Policies. The A1-PMS
+configures A1 Policies in RAN nodes (near-RT RICs). It also keeps a synchronized copy of these in case the A1-PMS needs to restart.
+Periodically A1-PMS will check that the configured A1 Policies and A1 Policy Types are consistent with those in the managed near-RT RICs (and take action if not).
+
+Communications to near-RT RIC can be tunneled through a CCSDK/SDNC controller, using our SDNC A1-Adapter plugin.
 
-The A1 PMS provides support for fine granied access control, which is implemented by delegating the granting of access of A1 Policies to an external
-authorization provider.
+The A1-PMS also now supports fine-grained access control checks, whereby access requests can be forwarded to an external authorization provider.
