| JohnKeeney | c86b5ae | 2023-07-28 19:25:14 +0100 | [diff] [blame] | 29 | The A1 Policy Management Service provides an API for accessing of A1 Policies. The A1-PMS |
| 30 | 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. |
| 31 | 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). |

| JohnKeeney | c86b5ae | 2023-07-28 19:25:14 +0100 | [diff] [blame] | 33 | Communications to near-RT RIC can be tunneled through a CCSDK/SDNC controller, using our SDNC A1-Adapter plugin. |
| PatrikBuhr | 9f1d949 | 2023-04-17 13:00:15 +0200 | [diff] [blame] | 34 | |
| JohnKeeney | c86b5ae | 2023-07-28 19:25:14 +0100 | [diff] [blame] | 35 | The A1-PMS now also supports fine-grained access control checks, whereby access requests can be forwarded to an external authorization provider. |
