Zero Usage Report Suppression

The SMF relays the offline resource usage report from the UPF to the CHF if any of the following conditions is met:

  • Reporting type is immediate.

  • Reporting type is deferred and the maximum number of deferred reporting is crossed.

The usage report includes the charging records with zero value as well. These zero value records (UUC and CDR-U) occupy unnecessary disk space on the CHF. To avoid this issue, the SMF leverages new configuration to control the offline charging records with zero byte data count.

When you configure the offline zero-usage CLI command in the Charging Profile configuration mode, the SMF relays the usage to the CHF without any overload of UUC or CDR-U.

The users can select the UUC or CDRs they want to suppress based on the CLI configuration.

Important

The CDR release is never be suppressed even if the offline zero-usage drop cdr command is configured in the Charging Profile configuration mode.

For details on the configuration, see the Configuring Zero Usage Report Suppression section.
