PCC Rule Error Handling
If the installation/activation of one or more PCC rules fails, the PCEF communicates the failure to the PCRF by
including one or more Charging-Rule-Report AVP(s) in either a CCR or an RAA command for the affected PCC rules.
Within each Charging-Rule-Report AVP, the PCEF identifies the failed PCC rule(s) by including the Charging-Rule-
Name AVP(s) or Charging-Rule-Base-Name AVP(s), identifies the failed reason code by including a Rule-Failure-Code
AVP, and includes the PCC-Rule-Status AVP.

If the installation/activation of one or more new PCC rules (that is, rules that were not previously successfully installed)
fail, the PCEF sets the PCC-Rule-Status to INACTIVE for both the PUSH and the PULL modes.

If a PCC rule was successfully installed/activated, but can no longer be enforced by the PCEF, the PCEF sends the
PCRF a new CCR command and includes the Charging-Rule-Report AVP. The PCEF includes the Rule-Failure-Code
AVP within the Charging-Rule-Report AVP and sets the PCC-Rule-Status to INACTIVE.

AVP within the Charging-Rule-Report AVP and sets the PCC-Rule-Status to INACTIVE.
In the HA/PDSN Gx implementation, the following rule failure codes are supported:
RATING_GROUP_ERROR (2)
SERVICE_IDENTIFIER_ERROR (3)
GW/PCEF_MALFUNCTION (4)
RESOURCES_LIMITATION (5)
If the installation/activation of one or more PCC rules fails during RAR procedure, the RAA command is sent with the
Experimental-Result-Code AVP set to DIAMETER_PCC_RULE_EVENT (5142).

Time of the Day Procedures
PCEF performs PCC rule request as instructed by the PCRF. Revalidation-Time when set by the PCRF, causes the
PCEF to trigger a PCRF interaction to request PCC rules from the PCRF for an established IP-CAN session. The PCEF
stops the timer once the PCEF triggers a REVALIDATION_TIMEOUT event.

When installed, the PCC rule is inactive. If Rule-Activation-Time / Rule-Deactivation-Time is specified, then the PCEF
sets the rule active / inactive after that time.

Support for Firewall Policy on Gx
The Diameter AVP “SN-Firewall-Policy” has been added to the Diameter dynamic dictionary to support Firewall policy
on Gx interface. This AVP can be encoded in CCA-I message to apply/overwrite the fw-and-nat policy that has either
been statically assigned to the PDP context via APN configuration or dynamically assigned via RADIUS in Access-
Accept. This AVP can also parsed in any CCA-U or RAR message to modify the fw-and-nat policy that is currently
assigned to the PDP context.

Charging Control
Important:
In the HA/PDSN Rel. 8 Gx implementation, offline charging is not supported.
Charging Control is the process of associating packets belonging to an SDF to a charging key, and applying online
charging as appropriate. FBC handles differentiated charging of the bearer usage based on real-time analysis of the
SDFs. In order to allow for charging control, the information in the PCC rule identifies the SDF and specifies the
parameters for charging control. The PCC rule information may depend on subscription data.

Online charging is supported via the Gy interface. In the case of online charging, it is possible to apply an online
charging action upon PCEF events (for example, re-authorization upon QoS change).
