Enhancement to Gx-Plus Application

The following enhancements to the Gx-Plus client application on the BNG are available:

• When a monitored service is deactivated separate from a subscriber logout, the CCR-U indicates that the service is no longer active and includes the service's usage data.
• The router updates the monitoring key and threshold values when they are received in a RAR message from the PCRF.
• A CCR-U is sent to the PCRF after the router sends an RAA message in response to an RAR message that requests service activations or deactivations.
• When the PCRF returns threshold values that are lower than the current values, the new threshold becomes the sum of the current value and the returned value.
• The PCEF has default minimum threshold values. If the change between the current value and the value returned by the PCRF is less than the minimum value, then the new value is adjusted to the minimum.
• The CCR-I message includes the Diameter AVP Subscription-Id attribute (443) with the Subscription-Id-Type Diameter AVP sub-attribute (450) set to 4 (END_USER_PRIVATE) and the Subscription-Id-Data Diameter AVP sub-attribute (444) set to reserved.
