Configuration After Upgrade

When a network that is already running Policy DRA is upgraded to DSR 5.1, several changes are performed automatically to prepare for PCRF Pooling, but backwards compatibility is maintained for all aspects of Policy DRA. The following changes occur automatically:

1. New entries appear in the Policy DRA > Configuration folder at the NOAM.
   • PCRF Pools
   • PCRF Sub-Pools Selection Rules
2. New entries appear in the Policy DRA -> Configuration folder at each SOAM.
   • PCRF Pools (read only at the SOAM)
   • PCRF Pool To PRT Mapping
   • PCRF Sub-Pool Selection Rules (read only at the SOAM)
3. A PCRF Pool called Default is created in Policy DRA -> Configuration -> PCRF Pools.
4. All configured APNs are mapped to the Default PCRF Pool. This can be seen on the NOAM GUI at Policy DRA > Configuration > Access Point Names.
5. The PCRF Pooling functionality is not Enabled. This can be seen on the NOAM GUI at Policy DRA > Configuration > Network-Wide Options.
6. There are no PCRF Sub-Pool Selection Rules configured on the NOAM GUI at Policy DRA > Configuration > PCRF Sub-Pool Selection Rules.
7. The Default PCRF Pool is mapped at each site to the same PRT table that was configured for new bindings on the SOAM GUI at Policy DRA > Configuration > Site Options in Peer Route Table Name. The new mapping can be seen on the SOAM GUI at Policy DRA > Configuration > PCRF Pool to PRT Mapping.
   Note: The GUI field for the PRT table for new bindings previously configured at Policy DRA > Configuration > Site Options is deprecated by Pooling.
8. The new Error Condition to be used when a binding capable session initiation request arrives with an unconfigured APN or no APN, defaults to IANA Diameter response code 3002. This can be seen on the SOAM GUI at Policy DRA > Configuration > Error Codes for Error Condition "Missing Or Unconfigured APN".
   Note:

   After upgrading to the release that supports PCRF Pooling, but prior to enabling the PCRF Pooling functionality, the following changes to Policy DRA configuration are in place:

   Prior to enabling PCRF Pooling, no request will be rejected due to a missing or unconfigured APN.
