AAA – Authentication, Authorization and Accounting

AAA — Authentication, Authorization and Accounting

As defined by industry standards, AAA stands for Authentication, Authorization and Accounting, and the Diameter-based Protocol AAAS stands for Authentication, Authorization and Accounting with Secure Transport. These protocols were defined by the IETF in RFC 6733 and provide an AAA framework for applications such as network access or IP mobility in both local and roaming situations.

And this is exactly what AAA from Summa Networks does — secure access to your network under different scenarios to enable use cases like VoWiFi, use of secondary devices, and access from WiFi networks.

Supported 3GPP interfaces

• SWx. To connect to an HSS.
• SWm. Enables the connection to an ePDG for VoWiFi.
• S6b. It allows connection from AAA to PGW.
• Sta. Trusted non-3GPP access.
• SWa. Untrusted non-3GPP access.

Flexible deployment

Summa Networks AAA can be deployed as a stand-alone product to connect to existing HSS, ePDG, PGW. As a 3GPP standard compliant product, it can interwork with any other standard elements. Summa Networks AAA is offered as well integrated with Summa Networks HSS as a single piece of software. This bundling creates a number of advantages for carriers:

• Both network functions are deployed in the same HW, no need for extra resources or communication links.
• No need for interoperability testing as products come pre-integrated and pre-tested.
• Functions are in the same instance so M&S are done over the same SW instance.

Use cases

Summa Networks AAA cover several functional cases.

• Trusted, untrusted access. Non-3GPP connections into your network, from WiFi networks to IoT devices.
• VoWiFi. Connection from mobile devices connected to WiFi networks to perform calls over WiFi.
• Entitlement server. Securely connect extra devices from a subscriber (wearable SIM or eSIM devices).
