Siemens and Convergys Implement Convergent Charging Solution at Telkomsel

Cincinnati and Djakarta; September 27, 2005) – – Indonesias premier cellular and wireless network operator Telkomsel has gone live with the first phase of Siemens (NYSE: SI) market-leading, real-time, convergent charging solution, charge@once, that features Infinys [tm] Rating software from Convergys Corporation (NYSE: CVG). Telkomsel obtained the advanced solution to deliver the first-ever, truly convergent pre- and post-paid rating and billing of individual customer segments regardless of payment options. The solution currently supports more than 21 million subscribers.

With the initial implementation by Siemens and Convergys now completed, Telkomsel is using the convergent charging solution to support its geographically complex business that spans over 13,000 islands. The solution satisfied Telkomsels rigorous IT, engineering, and network requirements. It is now supporting an operation that has more than 54 percent of the mobile market in Indonesia and provides network coverage to more than 90 percent of the countrys population, including corporate and private customers.

The architecturally advanced solution, featuring Infinys as the embedded rater on Siemens Charging, enables Telkomsel to explore the full range of convergent pre- and post-paid capabilities. These include real-time checking of credit limits, flexible charge and packages adjustment, as well as the use of bonus schemes and hybrid offers that help enhance customer loyalty and average revenue per user across all subscribers and service types.

The success of this project reaffirms our decision to partner with Siemens and Convergys, said Arman Hazairin, Vice President Information and Technology Telkomsel. We operate in an increasingly competitive market, so it is imperative that we can innovate around products and differentiate our offerings from those of competitors. The charge@once solution enables this, supports our drive to become even more customer-focused, and provides a platform for developing new revenue streams and achieving long-term growth.

“Completing the first phase of the implementation, supporting the complete customer base with a comprehensive real-time solution, and providing maximum charging flexibility at Telkomsel are major milestones for the Siemens convergent charging system, charge@once, featuring online rating from Infinys, said Volker Ziegler, President of Applications and Solutions at Siemens COM . Together with Convergys, we are demonstrating the real-world viability of our solution in a market where similar projects involving other suppliers have not yet been successful. Upon completion, the OPEX-effective solution will place Telkomsel in a unique position, enabling it to respond more quickly to changing market conditions, alter prices, and create discounts or promotions with an ease and alacrity hitherto unattainable.

Telkomsel is already seeing the benefits of a solution that effectively joins the high availability and scalability needed to support a tier-one operation with the real-time functionality and flexibility required to drive a customer-focused business, said Dave Dougherty, President and Chief Operating Officer of Convergys . This project showcases both the capabilities of the worlds first truly commercially operational online charging solution and the benefits of the close working relationship between Convergys and Siemens.

Operators needs for convergent online charging systems are increasing alongside the ever-expanding range of new multimedia data services for the online environment. The ability to handle both pre-paid and post-paid transactions in real time is critical if customers and providers are to quickly check usage limits and status of account balances in real time. This capability, provided by the Siemens and Convergys solution, allows customers to make informed decisions about their usage and expenditures while enabling operators to better manage their risk of revenue exposure. The solution also permits operators to constantly expand the existing charging structures and map new business and billing models in the charging system, which were once restricted to the post-paid offline environment.
