Transition from ISP to LTE Carrier - with the help of Radiator products

Recently, we have seen a transition with many operators evolving from traditional Internet Service Providers (ISPs) to LTE carriers who provide fixed line, WiFi, and mobile connections. At the same time, their needs for authentication, authorization, and accounting (AAA) become more complex. As an example, on top of a standard RADIUS AAA infrastructure, these carriers may need Diameter interfaces and a 3GPP AAA server.

For Radiator customers, we have made this transition as easy as possible - and with the flexibility of Radiator, it is easy to bring it to different infrastructures as a new solution.

How Radiator can help

As many of our customers have evolved from ISPs to LTE Carriers, their needs for different features have evolved at the same time. For these needs, we have developed Radiator Carrier class product line. In order to ensure cost-effective solutions, we offer a modular approach where you can purchase only the components that you will need in your project.

For example, many of our customers have used Radiator for both fixed and WiFi access for years. When they need to enable VoWiFi calling features, they can just add Radiator SIM Module to their network, and in this way, enable different EAP-SIM / EAP-AKA / EAP-AKA’ authentication methods and have a fully featured 3GPP AAA Server in their network as well.

Another example is our Radiator GBA/BSF Module that provides easy authentication for VoLTE supplementary services. This way you can ensure that VoLTE supplementary services (call forwarding, knocking, call barring) are in use in your LTE infrastructure without resorting to 2G/3G infrastructure.

If you are interested in Radiator features such as Diameter interfaces, online charging, VoWiFi, or 3GPP AAA Server, you can find more details in our website or contact our sales team at sales@radiatorsoftware.com. We will be happy to help you with your project.

More interoperability with Radiator GBA/BSF Support Module v. 1.3

We are happy to announce Radiator GBA/BSF Support Module v. 1.3.

With Generic Bootstrapping Architecture (GBA), it is possible to provide seamless authentication for VoLTE Supplementary Services. This enables the end user to manage services, such as call forwarding, knocking and video call forwarding without switching networks or extra usernames and passwords.

Radiator GBA/BSF Support Module works as an authentication proxy between the end-user user device and the HSS. It authenticates the user requests, and also separates the authentication procedure and the Application Specific server (AS) functionality into different logical entities, for example, RCS (rich communication suite) services mentioned above.

What is new?

We have added interoperability fixes, and successful testing has now been done with user equipment from following vendors:

• Samsung
• Microsoft
• Apple

New features also include fixed username checks and fixed access handlers to work even when client does not send the HTTP user agent header. You can see all the updates from Radiator GBA/BSF Support module revision history.

Do you want to know more?

We are happy to provide more information, use cases and benefits about Radiator GBA/BSF Support Module. Just contact our team at info@open.com.au and we will tell you more.

VoLTE RCS is getting more support - be ready with Radiator

In Mobile World Congress last week, Google and several global operators announced the launch of a mobile industry initiative to accelerate the availability of Rich Communications Services (RCS) in Android. Operators have agreed to transition toward a common, universal profile based on the GSMA's RCS specifications and an Android RCS client provided by Google in collaboration with operators and OEMs.

For telcos and their customers, the improved user equipment support means that they can get more out of their VoLTE networks. For example, the following Android RCS features will become part of operator messaging experience:

• Group chat
• Sharing high-resolution photos
• Reading receipts

Also, GSMA RCS advanced calling features will be supported in the future by Google.

Be ready with Radiator

The support for VoLTE RCS requires seamless authentication in operator networks. This can be implemented with Radiator GBA/BSF Support Module. Radiator GBA/BSF Support Module works as an authentication proxy between the end-user UE and HSS. It authenticates the user requests, and separates the authentication procedure and the Application Specific server (AS) functions to different logical entities – for example, call forwarding and other Rich Communication Services.

Authentication architecture, when your end user device supports VoLTE RCS

We have already deployed Radiator GBA/BSF Support module to real operator networks in order to provide support for seamless VoLTE RCS authentication. In case you are interested in our solution, please contact our team at support info@open.com.au.

Implementing VoLTE supplementary services with Radiator GBA/BSF

Generic Bootstrapping Architecture (GBA) is a technology that enables the authentication of a user. This authentication is possible if the user owns a valid identity on an HSS (Home Subscriber Server). GBA is standardised at the 3GPP. The user authentication is instantiated by a shared secret, for example, a SIM card inside the mobile phone and the other is on the HSS.

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.

One example architecture when using Radiator GBA/BSF module for VoLTE Supplementary Services

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.

Need for VoLTE Supplementary Services in your own network?
