BEIJING/SANTA CLARA, Calif.--(BUSINESS WIRE)--Aug. 17, 2001

AsiaInfo Holdings, Inc. (Nasdaq:ASIA), a leading provider of software products and infrastructure solutions for next generation network operators in China, announced today it has signed a contract with China Unicom to build a billing system for its new CDMA network.

During the initial phase of the project, AsiaInfo will provide integration services and its leading convergent billing software, AICBS (AsiaInfo Convergent Billing System) to eight provincial subsidiaries of China Unicom. Upon completion of the project, the billing system will serve approximately 30% of the customer's national CDMA network capacity.

In February 2001, China Unicom officially announced that it would initiate a CDMA project to build the largest and most advanced CDMA network in the world, in addition to its existing GSM network. This new technology offers a flexible solution for mobile operators in their impending transition toward 3G technology. After the first phase of the project, China Unicom expects to increase its network capacity by 10 million per year.

Among the vendors chosen to provide infrastructure and software support to this national project, AsiaInfo was selected to provide support to more provinces than any of its competitors. With its world-class software products and experienced local delivery team, AsiaInfo's advantages over local vendors and international competitors will continue to help sustain and enhance its leadership in the CDMA market.

"This contract win represents a significant success of our growth strategy to expand Internet-centric products and solutions to support the overall telecommunications industry. The wireless market is experiencing tremendous growth in China. We are committed to our customers' success in capitalizing on this growth and will make every effort to leverage our technological, financial and operational strengths to become the top provider of software and solutions to China's wireless market," said James Ding, president and CEO of AsiaInfo.

"We are excited to be chosen as a leading vendor of China Unicom's CDMA billing solution, which again validates our strong R&D capability and current leadership in areas of emerging technology," commented Steve Zhang, senior vice president and general manager of Software Products at AsiaInfo.

China Unicom is the only mobile services provider in China that operates both GSM and CDMA networks. As of June 30, 2001, the company serviced more than 20 million GSM users.
