Authentication
When authenticating a user, the base station uses a third-party RADIUS or
Diameter server known as an AAA (Authentication, Authorization and Accounting)
server to authenticate the mobile or subscriber stations.
The following figure shows a base station using an AAA server to authenticate
mobile station MS, allowing it to access the Internet.

In this figure, the dashed arrow shows the PKM (Privacy Key Management)
secured connection between the mobile station and the base station, and the solid
