Important:
In this release, coordination of authorized QoS scopes in mixed mode (BCM = UE_NW) is not
supported.
Provisioning of Authorized QoS Per QCI: If the PCEF performs the bearer binding, the PCRF may
provision an authorized QoS per QCI for non-GBR bearer QCI values. If the PCRF performs the
bearer binding the PCRF does not provision an authorized QoS per QCI. The PCRF does not
provision an authorized QoS per QCI for GBR bearer QCI values.
bearer binding the PCRF does not provision an authorized QoS per QCI. The PCRF does not
provision an authorized QoS per QCI for GBR bearer QCI values.
Policy Enforcement for Authorized QoS per QCI: The PCEF can receive an authorized QoS per QCI
for non GBR-bearer QCI values.
Other Features:
Bearer Control Mode Selection: The PCEF may indicate, via the Gx reference point, a request for
Bearer Control Mode (BCM) selection at IP-CAN session establishment or IP-CAN session
modification (as a consequence of an SGSN change). It will be done using the ―PCC Rule Request‖
procedure.
modification (as a consequence of an SGSN change). It will be done using the ―PCC Rule Request‖
procedure.
PCC Rule Error Handling: If the installation/activation of one or more PCC rules fails, the PCEF
includes 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.

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 (i.e., rules which were not previously
successfully installed) fails, the PCEF sets the PCC-Rule-Status to INACTIVE for both the PUSH and
the PULL modes.

the PULL modes.
If a PCC rule was successfully installed/activated, but can no longer be enforced by the PCEF, the
PCEF shall send the PCRF a new CCR command and include a Charging-Rule-Report AVP. The
PCEF shall include the Rule-Failure-Code AVP within the Charging-Rule-Report AVP and shall set
the PCC-Rule-Status to INACTIVE.
PCEF shall send the PCRF a new CCR command and include a Charging-Rule-Report AVP. The
PCEF shall include the Rule-Failure-Code AVP within the Charging-Rule-Report AVP and shall set
the PCC-Rule-Status to INACTIVE.
Time of the Day Procedures: PCEF performs PCC rule request as instructed by the PCRF.
Revalidation-Time when set by the PCRF, shall cause the PCEF to trigger a PCRF interaction to
request PCC rules from the PCRF for an established IP CAN session. The PCEF shall stop the timer
once the PCEF triggers a REVALIDATION_TIMEOUT event.

Charging Control
Charging Control is the process of associating packets belonging to a SDF to a charging key, and applying online
charging and/or offline charging, as appropriate. Flow-based charging 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.

In the case of online charging, it is possible to apply an online charging action upon PCEF events (e.g. re-authorization
upon QoS change).
