OCS is the beating heart of any BSS system. The quality of your OCS defines how good your telecom billing really is. By charging both session-based and event-based services on a single platform, it allows for convergence in billing.
While there are many tech companies offering online charging solutions, not all are created equal. It's an extremely technical field. The lingo alone can be overwhelming.
Everyone in the telecom business has heard about OCS. However, due to lack of knowledge and probably due to expenses, some operators shy away from integrating it into their business operations.
