Chapter 6 Prepaid Billing Solution

Generic Call Flow

In Flow 4s, the Cisco AR 3.5 server converts the quota array received into VSAs and sends an Access-Accept with the assembled VSAs to the AAA client. Table 6-5lists the prepaid-specific VSAs that might be included in the Access-Accept response message sent to the AAA client. For more detailed information about the VSAs, refer to Vendor-Specific Attributes, page 6-10.

Flows 3c through 4s are repeated for every service started or restarted by the AAA client.

However, if the return parameters indicate that the authorization is rejected, an Access-Accept message is generated and sent to the client as shown in Table 6-6. When this type of error condition occurs, no other VSA is included in the Access-Accept message.

Accounting Start

In Flow 5c, the AAA client sends the Accounting Start. In Flow 6s, the Cisco AR 3.5 server replies with the Accounting-Response.

Data Flow

At this point, the data transfer begins. The AAA client monitors the subscriber’s allocated quotas for metering parameters. A subscriber’s Reauthorization request is generated when a quota for at least one of the metering parameters, is depleted.
