Feature Description

The Tarrif switch time functionality applies when a subscriber switches form one tarrif plan to another. The Tariff-Time-Change AVP is used to determine the tariff switch time, and the Monitoring-Time IE is used to support the Tarrif Time support functionality.

After a tariff timer expiry, the gateway accumulates the usage separately in a charging bucket and continues to consume from the original quota value. At the time of next reporting, (Quota exhausted or another control events) the gateway reports both usages (before and after tarrif time change) for the same charging bucket.
