Cisco and Openet has recently told OSS News Review that Turkcell, Turkey’s leading communications and technology company, has deployed a combined solution to provide a flexible charging system for its general packet radio service (GPRS) mobile data network.

The joint solution from Cisco and Openet,which went live at mobile operator Turkcell in June 2009, introduces intelligence into the network to enable the real-time packet inspection, rating and billing of individual customers’ mobile data usage. It helps the operator deliver and charge for pre- and post-paid data and next-generation services. As a result, Turkcell, which has a subscriber base of more than 36 million, is able to provide subscribers with several billing options: by application used, for combined services or by data bandwidth consumed.

* Openet’s FusionWorks Convergent Charging solution deployed at Turkcell is combined with the following Cisco® technologies:
o Cisco Enhanced Gateway GPRS Support Node (eGGSN), based on the high-performance Service Application Module for IP (SAMI) technology in the Cisco 7600 Series Router;
o Cisco Service Control Engine;
o Cisco Access Register

* This combined solution was selected to help prepare Turkcell for a surge in data traffic from the launch of its 3G network in July 2009.

* The Cisco eGGSN solution provides advanced processing of Internet Protocol (IP) flows for content-aware billing, filtering, management and analysis in a highly scalable, fault-tolerant package. The solution helps Turkcell to deliver personalized mobile data services to its customers.

* Openet’s FusionWorks Convergent Charging product verifies the subscriber identity, the type of service and the authorization to use the service; advises on charge and session management; and charges for the service. These capabilities provide the transactional intelligence that Turkcell requires for the accurate delivery of, and charging for, 3G services.

* As a complementary technology with the Service Control Engine, Cisco provides content inspection capabilities that enable Turkcell to control network traffic and monetize subscriber use. Currently, there are servers deployed in Istanbul, with plans to roll out additional servers in Ankara and to augment the existing hardware in Istanbul as more subscribers begin to use Turkcell’s 3G network for data services.

* The joint solution was previously deployed to handle data on Turkcell’s 2G network and was selected for its ability to scale exponentially as 3G data use grows and delivery speeds rise as high as 1,500 transactions per second. Turkcell’s 2G customer base consists predominantly of consumers using voice and SMS services.

* The ability to handle real-time GPRS transactions now allows Turkcell to maximize profitability from data services, thereby creating a commercially viable proposition to take to the enterprise market. What’s more, the solution is a 3rd Generation Partnership Project initiative that is IMS-standard-compliant and device-agnostic, so Turkcell can now handle the growing demand for next-generation services such as mobile TV and mobile Internet.

* Cisco Advanced Services provided end-to-end integration, deployment and support services working in close collaboration with Openet.
