The project goal was to develop Converged Rating and Charging Engine system that will provide rating and charging capabilities for Session (phone call), Event (SMS, MMS), and Data usage (Internet/bandwidth usage, OTT services usage). In addition, it had to enable rating and charging for external services exposed to it by API, so that the third-party systems could perform real-time rating and charging, money transfer and electronic top up. As a real-time OSS component, it was a key critical system in MNO and MVNO deployments.
