SAN JOSE, Calif. & SAN RAFAEL, Calif.--(BUSINESS WIRE)--April 3, 2002

Partnership Focused on Integrating Network Elements and Systems

Into a Mobile Services Architecture

Tahoe Networks, Inc., the emerging leader of network infrastructure at the Mobile Internet Edge(TM) (MIE) and Kabira Technologies, Inc., a leading provider of software solutions for convergent network services, today announced a marketing and technology partnership that will enable GPRS, CDMA and UMTS operators to rapidly integrate new mobile data services into their existing operations. As a result of the partnership, mobile operators will be able to accelerate the launch of innovative and revenue-generating mobile data services that are essential for the success of next generation wireless networks.

Unlike traditional IP infrastructure solutions that just provide connectivity, Kabira Technologies and Tahoe Networks' integrated solution will allow wireless operators to take full advantage of their IP network to deploy quality personalized data services while significantly improving time-to-market of service delivery.

"One of the biggest challenges facing wireless operators will be to integrate their existing wireless network and enterprise systems to introduce Internet data services within their current networks. Wireless operators need a solution to integrate separate physical subscriber, services, networks and business systems for voice and data services," said Grover Righter, vice president of technical strategy, Kabira Technologies.

"We're partnering with Kabira Technologies to expose IP services to billing systems, provisioning systems, and applications by integrating our interfaces and processes into Kabira's Infrastructure Server. As a result, mobile operators, system integrators, and application developers can rapidly deploy IP services offering new 3G wireless solutions. The solution reduces development and deployment times and costs, creating sustainable competitive advantage," said Alan Cohen, vice president of marketing, Tahoe Networks.

The partnership facilitates an open wireless services architecture for the introduction of IP capabilities. Such an architecture will extend the life of the investments made in legacy systems by combining Tahoe Networks' infrastructure and operations solutions with Kabira's mediation, provisioning and service activation frameworks.

"Success in wireless data, especially in mobile cellular networks will depend heavily upon deploying, provisioning and billing in a packet-based environment. This is a big leap for service operators which to date have operated almost exclusively with circuit switched systems. Air interface changes such as GPRS, EDGE and UMTS are only one piece of the puzzle. Carriers have to also deploy new systems to handle the IP traffic. That's going to require changes," said Ed Snyder, JP Morgan H&Q.

"The ability of the mobile operators to deploy, manage, and account for new services is greatly enhanced by data infrastructure and software that is both intelligent enough to collect application and user specific accounting information and dynamically adapt individual user's services based on triggers from billing mediation and other external systems," said Verne Anton, principal analyst, Gartner Group.

The Tahoe Networks' system will integrate with best-of-breed technologies like Kabira's Infrastructure Server to make the network operator an active participant in delivering value to subscribers and content providers. Tahoe Networks has received attention for its innovative approach to mobile data infrastructure. Kabira is in production at over 28 leading mobile operators around the world, ranging from 200,000 to over 14 million subscribers.
