Chargeable Events
PCC rules can be activated, deactivated, and modified at any time during the PDU session lifetime.
The following attributes can be modified by the PCF in a dynamic PCC rule active in the SMF:
-
Charging Key
-
Service Identifier
-
Measurement Method
Activities on PCC rules and QoS flows are not chargeable events. However, change of charging rule in PCC rules lead to chargeable events such as:
-
Start of service data flow
-
Termination of service data flow, for the last service data flow for the original PCC rule
The charging key (that is, rating group) is used to request online charging quota.
