Feature Description

Static PCC rules are configured in the SMF. These rules can be activated immediately upon PDU session establishment. Static rule is identified by the ruledef configuration using the action priority CLI command.

The local configuration on SMF represents the rulebase which is sent to the UPF during session establishment. The SMF uses the configuration representing the PCC rules, QoS Desc, and Charging Data received from PCF to perform QoS flow binding. This configuration is present in the UPF as well. The SMF does not send the PDRs, QERs, and FARs, instead sends only the rulebase name in a default PDR (referred as rulebase PDR) over the N4 interface. The UPF generates the PDRs, FARs, QERs, and URRs for predefined rules based on the rulebase configuration.

Important

The Static PCC Rules Support on SMF is applicable to both 4G and 5G calls.
