Radiator GBA/BSF Module: Seamless authentication to VoLTE Supplementary services

VoLTE (Voice over LTE) calling is now being used by mobile carriers in their networks all over the world.

With VoLTE calling, there is no dependency on the legacy circuit-switched voice network to be maintained, which has many benefits for the carrier infrastructure. As a part of this, the carrier network will need an easy way to authenticate also to VoLTE supplementary services, such as call forwarding, knocking and call barring.

For this need, we have created Radiator GBA/BSF Module on top of our Radiator. Radiator GBA/BSF Module makes authentication for VoLTE supplementary services easy by using General Bootstrapping Architecture (GBA). In addition to this GBA enables also extending SIM authentication to any operator WWW services. In addition, SIM authentication itself has authentication federation support, which can be used to produce services across virtual and other operators.

Our product, Radiator GBA/BSF Support Module works as an authentication proxy between the end-user UE and HSS. It authenticates user requests, and also separates the authentication procedure and the Application Specific server (AS) specific application logic to different logical entities.
