Quota Management

The SMF requests quota from the CHF upon meeting any of the following conditions:

  • The Rating Group (RG) is installed for the first time and the charging method is Online for the dynamic rule.

  • The start of traffic trigger is initiated from the UPF for the RG in the case of static or predefined rules.

  • A specific trigger type, as defined in the 3GPP specification 32.255, is received in the usage report for the online charging service from the UPF.

The SMF uses the quota request always CLI command to request the quota always. This CLI command is available in the Charging Profile configuration mode. Upon configuring this CLI command, the SMF always requests for quota when reporting the usage to the CHF for the online services. The quota requesting ends when the charging service stops.

Irrespective of the quota request [ always | standard ] CLI configuration, the quota request is disabled for the trigger type "qht" configured through the quota suppress triggers CLI command.

For command details, see the Charging Profile Configuration section in the SMF Charging chapter of this guide.
