Sky Link and Lucent Technologies Enhance CDMA450 Network in Moscow with CDMA2000 1xEV-DO Technology and Lay Foundation for IMS-Based Multimedia Services.

MOSCOW -- Sky Link Moscow to Deploy Lucent's Super Distributed Home Location Register (S-DHLR) and Flexent Packet Gateway - Key Elements of Lucent's IP Multimedia Subsystem Solution

Sky Link Moscow and Lucent Technologies (NYSE: LU) today announced that the two companies have initiated a project to enhance Sky Link's CDMA450 network in Moscow and its surrounding areas to support higher-speed mobile data services and blended "lifestyle" applications that combine voice, video, multimedia and other data capabilities. The upgrade will incorporate Lucent's CDMA2000(R) 1xEV-DO (Evolution-Data Optimized) technology to support mobile data services at speeds of up to 2.4 Megabits per second (Mbps) as well as key elements of Lucent's IP Multimedia Subsystem (IMS) solution.

As part of the project, Lucent will provide additional Flexent(R) CDMA450 base stations and upgrade a second Mobile Switching Center (MSC). Lucent also will provide its Flexent(R) Packet Gateway (FPG) and Super-Distributed Home Location Register (S-DHLR) -- part of Lucent's IMS solution. Lucent Worldwide Services will ensure a smooth network deployment by providing installation, integration, and training and support services.

"By upgrading our network and implementing new solutions, we are building a strong foundation for our continued network development and making important and practical steps towards next-generation, personalized lifestyle services that keep pace with the modern multimedia world," said Valery Guzeev, first deputy director, Sky Link Moscow.

"Our EV-DO and IMS solutions will help Sky Link preserve existing network investments and help speed time-to-market for new applications, increasing customer satisfaction and aiding in the attraction of new subscribers," said Dmitry Kamensky, general director, Lucent Technologies in Russia and CIS. "For subscribers, IMS means quick and easy access to communication services anytime and anywhere with the device of their choice and EV-DO means super-fast mobile data services."

The Lucent S-DHLR is an advanced customer information data server that enables the creation of a single subscriber profile for each customer and all of the services they use, in contrast to the traditional method of maintaining individual subscriber databases for each service. It also provides support for a wide variety of voice and data services on mobile, wireline and converged networks. Sky Link's migration from a traditional Home Location Register (HLR) to the new Lucent S-DHLR will reduce the complexity of managing subscriber data, make it easier to offer their subscribers customized service bundles and provide a consistent look and feel for subscribers' services even when roaming across multiple network types such as GSM, W-CDMA/UMTS, WiFi and wireline networks or onto another operator's network.

The Flexent(R) Packet Gateway solution consists of Lucent Packetstar(R) (PSAX) media gateways, which support packet voice transfer on transport networks and the interaction with POTS (Plain Old Telephone Service) nodes, and the Lucent Network Controller, which provides SS7 signal processing and media gateway and media resource management. The FPG solution will provide Sky Link with next-generation switching capabilities and will interoperate seamlessly with the S-DHLR and prepaid platforms. It also is compatible with multiple network types, such as GSM and W-CDMA/UMTS, and supports interaction with IP-based networks and various legacy networks such as POTS. This single platform provides Sky Link with an efficient way to migrate to an IMS-based next-generation network, as it supports other Lucent solutions such as the IMS Session Manager.
