Optional 3GPP AAA Module
The 3GPP AAA module enables the Diameter functionality in SBR Carrier to support non-3GPP network services. SBR Carrier performs EAP-AKA and EAP-AKA’ based authentication, subscription authorization, and accounting in non-3GPP networks. SBR Carrier converts RADIUS messages received from non-3GPP networks to Diameter messages and forwards Diameter messages to a Home Subscriber Server (HSS). When the HSS replies with Diameter messages, SBR Carrier converts them to RADIUS messages and replies to the non-3GPP client.
