7.4 Authentication, Authorization, and Accounting (AAA) Server
Installation
As part of the WiMAX Profile C architecture, the AAA server is a key element providing subscriber and
device authentication as well as configuration. The BWG communicates using RADIUS with the AAA
server for subscriber/device authentication and configuration. The configuration information is then
relayed by the BWG to the BS using the R6 interface.
Cisco’s BWG open architecture design makes it compatible with any AAA server that also uses open
architecture protocols. In Release 10.0, all subscriber configuration information is captured in an
AAA database.
As a subscriber attempts to access the network, the SS communicates with the BS. The BS contacts the
BWG which in turn interfaces with the AAA database to check authentication and authorization and to
acquire the subscriber’s profile. Assuming the subscriber’s data exists and the subscriber is approved for
network access, the BWG sends the information to the BS to provide service to the subscriber.
Cisco offers its own AAA application called the Cisco Access Registrar, or CAR, as part of the WiMAX
end-to-end solution (
Figure 7-7).
