PCRF should know the charging identifier assigned to the bearers to correlate the charging information. PCRF requests
the PCEF to provide the Access-Network-Charging-Identifier-Gx AVP associated to dynamic rules. To support this, the
PCRF provides the Event-Trigger AVP with a new value CHARGING_CORRELATION_EXCHANGE (28) and a new
Charging-Correlation-Indicator AVP indicating CHARGING_IDENTIFIER_REQUIRED within the Charging-Rule-
Install AVP.

Previous Behavior: The AVP “Access-Network-Charging-Identifier-Gx” was always sent in the CCR-U message. This
AVP was also sent in RAA message by the chassis.

New Behavior: This AVP is sent in CCR-U only when event trigger 28 is enabled and the new AVP “Charging-

If the update of the rule changes the QCI/ARP of the rule and this leads to binding of the rule to a different bearer, the
chassis sends out CCR-U to PCRF indicating the new charging ID in Access-Network-Charging-Identifier-Gx AVP.

Important:
This behavior change is applicable only for dpca-custom15 and r8-gx-standard dictionaries and is
valid for bearer type GTP and PMIP only.
In the case of RAR, when Charging-Correlation-Indicator AVP is present and event trigger 28 is present in RAR and
Supported Features is Rel. 10 at both PCRF and chassis, CCR-U will be sent for all bearers.

Support for Peer Selection at Diabase
Applicable Product(s): GGSN, P-GW
In the earlier Gx implementation, Diameter Policy Control Application has the limitation to mandatorily configure hosts
as part of IMS Authorization service or associate a host template and select the hosts to be communicated for each
subscriber session. Since the peer selection can happen at diabase and application need not select any hosts, this feature
is developed to remove the restrictions imposed in the application and allow diabase to pick the peers in a round robin
fashion. In addition, this feature will take care of peer selection at diabase even when the hosts picked by application are
not active. This change in behavior is controlled through the CLI command “

fashion. In addition, this feature will take care of peer selection at diabase even when the hosts picked by application are
not active. This change in behavior is controlled through the CLI command “
endpoint-peer-select
” as the default
behavior is to drop the call if the server discovery fails at application.
When the peers are selected from endpoint, the output of CLI command “
show ims-authorization sessions
full
” does not display these fields “Primary PCRF Server” and “Secondary PCRF Server”.

Support for PS-Furnish-Charging-Information in Gy
Applicable Product(s): GGSN, P-GW
Support is added to all DCCA Gy dictionaries for parsing the PS-Furnish-Charging-Information AVP received in CCA
message. The Furnish Charging Information (FCI) feature is based on the 3GPP standard specification 32.251.
message. The Furnish Charging Information (FCI) feature is based on the 3GPP standard specification 32.251.
FCI when received in CCA will be parsed in the PGW-CDRs if both online and offline charging are enabled.
