SSG Prepaid
SSG Prepaid
The SSG Prepaid feature allows a user to connect to a service if the user has prepaid for the service. SSG checks a subscriber’s available credit to determine whether to connect the subscriber to the service and how long the connection can last. The billing server administers the subscriber’s credit as a series of quotas. These quotas are allotments of available credit and represent the duration of use, expressed in seconds.
Note The Cisco 10000 series router does not support quotas that are based on allowable data volume. The router supports only
To obtain the first quota for a connection, SSG submits an authorization request to the AAA server. The
AAAserver contacts the prepaid billing server, which forwards the quota values to SSG. SSG then monitors the connection to track the quota usage. When the quota runs out, SSG performs reauthorization. During reauthorization, the billing server can provide SSG with an additional quota if there is available credit. If no further quota is provided, SSG logs off the user.
