Supported Diameter Methods
ASN Gateway supports the following Diameter methods for EAP authentication and authorization:
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.
