Adjusting the Interim Accounting Interval for a Service

In the Interim Interval box, you define a formula to dynamically adjust the interim accounting interval for each service based on the subscriber’s remaining resources and use of the network for that service. Each service in the SRC-VTA can use a different formula. You can configure the SRC-VTA software to evaluate the formula to obtain the accounting intervals. Depending on the result, the SRC-VTA performs the following functions:

• If the result is zero, the SRC-VTA disables interim accounting.
• If the result is a negative number, the SRC-VTA does not change the interim accounting interval.
• If the result is a positive number, the SRC-VTA changes the interim accounting interval to this value.

The variables are categorized as:

• Current service—Provides session data of the service for the current service-tracking event.
• Other service—Provides service session usage information for another subscriber service for the current service-tracking event. For example, if a subscriber has two quota services, QuotaLocal and QuotaInternet, the interim formula for QuotaLocal can provide usage information to QuotaInternet.
• Account balance—Provides the balance in the account.
