HOTSPOT GATEWAY
246 The Subscriber Interface
Authorization and Billing
As a gateway device, the HSG enables plug-and-play access to broadband networks.
Broadband network solution providers can now offer their subscribers a wide range of
high speed services, including access to the Internet. Of course, a high speed Internet
connection is not free – subscribers pay an access fee, based on the duration of their
connection. Additionally, subscribers may want to take advantage of the solution
provider’s local network services (for example, purchasing goods and local services).
In either case, the subscriber is required to pay. And naturally, subscribers expect to
pay only for the services rendered to them.
In any environment, billing is a complex process. It requires accurate data collection
and reconciliation, a means to validate and protect the data, and an efficient method
for collecting payments.
The HSG offers powerful billing support functionality called “Authentication,
Authorization, and Accounting.” This feature (also known as AAA) employs a
combination of command routines designed to create a flexible, efficient, and secure
billing environment. For example, when a subscriber logs into the system, their
unique MAC address is placed into an authorization table. The system then
authenticates the subscriber’s MAC address and billing information before allowing
them to access the Internet and make online purchases.
