With GBA, it is possible to provide VoLTE Supplementary Services, for example, Call Forwarding in VoLTE. Call Forwarding is an example of use case that cannot be pre-configured for all the subscribers because users want to configure their own forwarding number. With Radiator GBA/BSF module, this is possible to done in your VoLTE network – without the need to drop the user from VoLTE to other network.
How this is done with Radiator?
One of our customers had a need for VoLTE Supplementary Services in their network, and as a part of product development, a new Radiator GBA/BSF module was introduced to meet their needs.

As it is shown in picture above, Radiator GBA/BSF module will work as a authentication proxy between the end-user UE and HSS. It will authenticate user requests, and also separate the authentication procedure and the Application Specific server (AS) specific application logic to different logical entities – such as VoLTE Supplementary Services.
After the authentication procedure has been completed, Radiator GBA/BSF module assumes the role of a reverse proxy, i.e. the AP forwards HTTP requests originating from the UE to the correct AS, and returns corresponding HTTP responses from the AS to the originating UE.
