Overview of ISG Support for Prepaid Billing
ISG prepaid billing support allows ISG to check the available credit for a subscriber to determine
whether to activate the service for the subscriber and how long the session can last. The subscriber’s
credit is administered by a prepaid billing server as a series of quotas representing either a duration of
use (in seconds) or an allowable data volume (in bytes). A quota is an allotment, or fragment, of available
credit. Allocating quotas in fragments rather than providing all the credit at once enables ISG to support
the use of credit for multiple simultaneous prepaid sessions.
ISG uses the RADIUS protocol to facilitate interaction between ISG and external authentication,
authorization, and accounting (AAA) servers and prepaid billing servers. A single device can serve as
the AAA server and the billing server.
To obtain the first quota for a session, ISG submits an authorization request to the AAA server. The AAA
server contacts the prepaid billing server, which forwards the quota values to ISG. ISG then monitors the
session to track the quota usage. When the quota runs out or a specified limit is reached, ISG performs
