Ebru Yeldan, Head of Charging & Mediation Solutions at Turkcell, shares her company's big transformation program "Single Rating Engine" and what she thinks are the hot topics for operators today.

The main objective of the program was to increase control and transparency for Turkcell's 14 million postpaid subscribers by giving them real-time rating for all services and all traffic types, including roaming.

We interviewed Ebru Yeldan at the Ericsson OSS/BSS Summit held in Rome to hear how this transformation is just one of the ways Turkcell is putting its customers and their needs at the heart of its business.
