Indeed, it is. Online Charging System (OCS) is a worthy upgrade on the traditional prepaid and offline charging systems. It comes with real-time charging performance, which enable telecom operator to charge and rate both events and sessions in real-time. This attribute of OCS is very important as it paves the way for convergent billing. By procuring an OCS, you can deliver multiple services to your clients and only send them a single bill that reflects all charges.

Not only is it useful for customers, but it is also very good for your customer support reps as they are able to view all service transactions conveniently.
