Siemens and Time Warner Cable Successfully Demonstrate IMS, Setting the Stage for a Converged Blend of Personalized Wireless and Fixed Consumer Services; Bringing Entertainment, Telephones, Internet Applications and Wireless Together

Business Wire, May 2, 2006

BOCA RATON, Fla. & STAMFORD, Conn. -- Siemens Communications Inc. and Time Warner Cable today announced the successful demonstrations of fully integrated fixed line, mobile and WiFi broadband technologies via Internet protocol multimedia subsystem (IMS) standards to deliver fixed mobile convergence (FMC). The demonstrations highlight the operational value of adopting Siemens' IMS solutions and show how consumers can now enjoy shared multimedia applications, entertainment features and communication sessions - including converged wired and wireless solutions.

Time Warner Cable is one of the first cable operators to demonstrate the use of IMS at the company's Herndon, Va., facility. Time Warner Cable is using Siemens' technology to support a range of IP-based services. One demonstration used several online gaming scenarios to test the integration of both packet- and circuit-switched telephony networks as well as a range of different wireless and fixed technologies. The technology supported gaming between a user with a wireless device who was playing against an opponent on a fixed-line network device. The two companies have also demonstrated dual-mode handset usage, including seamless handoffs as users roamed from WiFi coverage - either at work and at home - to cellular coverage areas.

"IMS technology is an exciting new technology for consumers who want their devices to work seamlessly together - including presence-aware features that can direct calls, video and messages to devices that are currently in use and in ways that are most convenient for the end user at any given moment," said Mike LaJoie, Chief Technology Officer at Time Warner Cable.

"Rather than being limited in capabilities due to silos of network architectures, IMS promises a new world of seamless provisioning opportunities for broadband operators. This will include the ability of operators to rapidly and cost-effectively deploy highly personalized entertainment services."

Siemens is an industry leader in fixed mobile convergence, leveraging its global experience that cuts across both mobile and fixed networks. The company is a global leader in delivering voice over Internet protocol (VoIP) applications for cable service providers, enterprises, government organizations and others.

"The building blocks are here today to remove the obstacles created by fragmented network domains, protocols and devices," said Harald Braun, president, Siemens Networks Division, Siemens Communications Inc. "IMS is another significant step in the Siemens(R) LifeWorks(TM) vision to provide end-to-end service delivery platforms for the next generation of services that will help people get more enjoyment out of life and work."
