Volume and Duration-based Prepaid Accounting
Prepaid accounting is a licensed-enabled feature. The ASN Gateway supports both volume threshold and duration
threshold based prepaid accounting. Even though session-level accounting is performed for both volume and duration,
the number of bytes in a multi-flow session are applied to a duration-based configuration.
