CHF sends notify (RAR) after this condition is recovered for the session

Note
  • The error code 403 is not configured in the failure handling template.

  • CHARGING_NOT_APPLICABLE (Disable charging) for static and predefined rules is achieved by sending a proprietary IE “Charging Disabled” in subscriber params in N4 modification / establishment request, so that UPF does not generate Start of Traffic for the URRs pending for activation.
