EAP-Authentication and Key Agreement (EAP-AKA)
EAP-AKA uses symmetric cryptography based on pre-shared private client/server keys and challenge-response
mechanisms similar to other EAP methods. It verifies credentials for users of Removable User Identity Modules (R-
UIMs).

WiMAX Prepaid Accounting
The system supports prepaid accounting for clients on the ASN Gateway.
Clients can communicate directly to a home AAA server or be proxied through a visited network’s AAA server. The
following figure shows a typical prepaid network topology.

Volume and Duration-based Prepaid Accounting
Prepaid accounting is a licensed-enabled feature. The ASN Gateway supports both volume threshold and duration
threshold based prepaid accounting. Even though session-level accounting is performed for both volume and duration,
the number of bytes in a multi-flow session are applied to a duration-based configuration.

RADIUS attributes identify thresholds and quotas for both volume (number of bytes) and duration (length of session).
