Nokia is first with 3GPP Release 4 architecture for voice in 2G and 3G networks.
The Nokia MSC Server System, Nokia's new voice core network for 2G and 3G, has reached the volume delivery stage, and volume deployments of the solution are taking place worldwide.
The MSC Server System brings operators significant savings in the delivery of voice minutes by reducing the cost of building and operating mobile networks. The system is already used for live commercial voice traffic by leading operators in Europe and Asia-Pacific.
Nokia is the first vendor to provide a 3GPP Release 4 compliant MSC Server System that fully handles GSM/EDGE and WCDMA services in the same network elements, which means that migration to combined GSM/WCDMA networks can be accomplished cost-efficiently. Nokia's solution is also fully backwards compatible with GSM/EDGE and Release 99 WCDMA specifications and interfaces.
"The Nokia MSC Server System is a perfect solution for core network optimization, bringing significant cost-savings for operators. At the same time, it offers long-term investment protection, and will play an important role in networks compliant with 3GPP Release 5, Release 6 and Release 7 specifications," says Juha Äkräs, Senior Vice President, Core Networks, Networks, Nokia.
The Nokia MSC Server System allows operators to concentrate call control to larger centers, while distributing switching functions to locations close to traffic hot spots. It also enables a safe and standardized way to implement carrier-grade Voice over IP (VoIP) service in mobile networks. The MSC Server System brings considerable savings in operating expenditure for voice in both 2G and 3G networks, and enables significant cost-efficiencies also to operators with a pure GSM/EDGE circuit core network using TDM point-to-point connections.
Nokia is the world leader in mobile communications, driving the growth and sustainability of the broader mobility industry. Nokia is dedicated to enhancing people's lives and productivity by providing easy-to-use and innovative products like mobile phones, and solutions for imaging, games, media, mobile network operators and businesses. Nokia is a broadly held company with listings on five major exchanges.

Notes to the editor:
The Nokia MSC Server Solution is the new voice core solution for 2G and 3G. It is based on open standards and is specified in 3GPP Release 4. It is also fully backwards compatible with GSM and R99 WCDMA specifications and interfaces.
The MSC Server is the first architecture to enable a safe and standardized way to implement carrier-grade Voice over IP protocol (VoIP) service in mobile networks. This will further reduce the complexity and cost of network operation in 3GPP Release 4 networks. The MSC Server System can also share the same packet-based transport infrastructure with all other mobile and fixed telecommunications services.
The Nokia MSC Server enables significant operational expenditure (OPEX) savings in the delivery of voice minutes. Operational cost savings come from its high capacity and its simple and efficient network architecture. The Nokia MSC Server System delivers unparalleled performance, multi-protocol capabilities and significantly reduces the transmission bandwidth required for each voice call.
In practice, the Nokia MSC Server separates call control and switching into separate network elements, the Nokia MSC Server (MSS) and Nokia Multimedia Gateway (MGW). This means that the location of network elements and sites can be optimized. MSC Servers can be concentrated on a few sites located close to the operator's premises, while the Multimedia Gateways can be located at existing base station controller/radio network controller sites close to the traffic hot spots. Also interconnect points to other networks can be designed optimally, reducing the size of the transit layer in the network.
