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.
