Nowdays, more and more companies would like to employ AAA GW real-time rating, yet they are faced with many questions. In this article, some of these will be answered, conventional batch rating will be contrasted with realtime rating, and some benefits of the latter will be shown.
In conventional batch rating, all event data are read from CDR/EDR files after events are already finished. Event data are processed, rated, and charged.
In realtime rating, data are processed when events are attempted or even in progress. Events are authorized, reauthorized, and, at the end, charged.
When planning a realtime system, it needs to be designed in a way that minimizes the posibility of interrupting services or incurring any revenue losses. To minimize those, latency, high availability architecture, cm/dm separation per service for easier production maintainance, and efficient monitoring all have to be taken into consideration.
With realtime rating, prepaid and postpaid users can be accommodated in one system – such a system is called convergent billing. Realtime billing offers even more benefits, such as postpaid credit limits, and realtime feedback after customer usage.
