The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

During session establishment and modification, the SMF communicates with PCF over the N7 interface. When a user equipment (UE) establishes a packet data unit (PDU) session, the UE requires policies for session management. PCF stores the policies as Policy and Charging Control (PCC) rule IDs in the Policy Builder application. When SMF receives the session establishment request, SMF requests PCF to provide policies, PCF then sends the PCC rule ID. SMF uses the PCC rules to configure the UPF for various data flow tasks, such as shaping, policing to provide bandwidth, and charging functions.
PCF supports configuration of PCC rule ID for Rule and Rulebase. Rulebase is the collection of charging rule names. PCF sends this PCC rule ID to the SMF, and as per the PCC rule ID, the SMF searches the definition of these rules.
 Note |
Rule and Rulebase Name is equivalent to Charging Rule Name and Charging Rulebase Name that were present in PCRF. |
This section describes how to configure a PCC rule ID for Rule and Rulebase rules.
Log in to the Policy Builder application.
In the Service Configurations pane, click DynamicPccRule.
The dynamic PCC rule parameters appear.
Click the PCC Rule Id parameter and enter the Pcc_Rule_Id value.
Click Save.
