The business need

Being that the mobile VoIP services market has advanced, fring designed an innovative product that allows making phone calls from their application to mobile and landline phone networks. The Comarch Billing Cloud solution was selected in order to provide rating, charging and billing of services of this revolutionary business idea in real-time.

fring already provides a smartphone application that enables users to make voice/video calls and text chat for free in the fring network. As the next step it was decided to allow to make calls to mobile and landline phone users – the new service was called fringOut. fring planned to enable its subscribers to make phone calls from 1¢/minute to any country. To launch this service, fring needed a billing software for support. fringOut was to be built from scratch, with no guaranteed success, yet with a solid potential customer base of 10’s of millions of fringsters. The supporting software was expected to be flexible – start small and then grow with business while maintaining telcograde robustness. After reviewing several vendors, Comarch Billing Cloud was chosen as the solution that best fits fring needs.

The approach

As fringOut was a completely new service, fring was looking for a solution that would not only require little investment at the beginning, but one that would also be possible to extend in the future if the service was to prove successful. In this case, by choosing Comarch Cloud Billing, investing in hardware or technology was not necessary. Because the solution is based on the Comarch BSS Suite of COTS products, it offers a combination of a low-cost approach and product maturity. This unique mixture together with the stability and scalability (both technical and commercial) of Comarch Billing Cloud made Comarch an ideal partner for fring’s project.

The solution

 Comarch Billing Cloud is a modern solution, perfectly suited for start-ups because of its flexibility and short deployment time. It comes in a variety of business and licensing models including “pay-as-you-grow”. The final solution can be developed in an agile way, allowing required customizations to be delivered dynamically.

The service provides real-time charging, balance control and replenishment functionalities. The customer care module supports system operations, such as product catalog, user management or report generation. Every user can review their account history, credit and settings, using Web or a mobile self-care interface. The highly available Comarch Billing Cloud ensures expected performance and scalability. Real-time session control, necessary in the prepaid business model, is supported by a RADIUS server.

User registration is carried out online. The solution also provides integration with external business partners such as PayPal and G2S (gate2shop). Comarch Billing Cloud is hosted in the Comarch Data Center and is made available to fring via a Virtual Private Network (VPN), connecting over 20 fring data centers around the world.

  • Fast and effective integration was executed with fring’s infrastructure and external services such as PayPal and G2S (gate2shop) using Web services API.
