Fujitsu Selected as NTT DOCOMO's Core Network System Supplier for "Super 3G"

- Supplying everything from wireless base stations to core network systems -

Fujitsu Limited

Tokyo, September 26, 2008

Fujitsu Limited announced today that it has been selected by NTT DOCOMO, Inc. to be a supplier of core network systems for the carrier's next-generation Super 3G high-speed wireless communications network.

Fujitsu will supply components of the core network system Evolved Packet Core (EPC(1)), comprised of S-GW(2) systems, which handle data transmissions with mobile phone handsets, and P-GW(3) systems, which connect the core network to corporate and other external networks.

In 2006, NTT DOCOMO selected Fujitsu to develop and manufacture both wireless base stations and handsets for its Super 3G network, which is based on the emerging Long Term Evolution (LTE(4)) standard designed to enable high-speed transmission of large volumes of data. With this latest announcement, Fujitsu will be supplying comprehensive systems for the next-generation network, encompassing everything from wireless base stations and core network systems to mobile phones.

Leveraging Fujitsu's innovative IP technologies and switching technologies for base stations, the S-GW and P-GW systems comprehensively integrate the hardware and software being deployed globally by Nokia Siemens Networks(5). The technologies of the two companies combine to produce a single system with a flexible configuration designed for growth and changing traffic conditions that can still operate more efficiently and with smaller space requirements than its predecessors.

Fujitsu has built an excellent partnership with NTT DOCOMO over many years as a supplier of network infrastructure and mobile phone handsets. Building on that partnership to provide comprehensive support to Super 3G, Fujitsu will continue to provide high-quality, high-performance products and solutions.


  • [1] EPC

    Also referred to as System Architecture Evolution, this is a network architecture for a W-CDMA-based 3G core network, using the all-IP network that has been a goal for 3GPP.

  • [2] S-GW

    For handsets accessing Super 3G or 3G networks, this is a node implementing a relay for user data.

  • [3] P-GW

    A node implementing a connection between the EPC and an external network, such as IMS, an ISP, or a corporate network.

  • [4] LTE

    Long Term Evolution is a high-speed data communications specification for mobile phones and represents a step forward from the HSPA standard for high-speed data used on existing W-CDMA 3G networks. It aims for transmission speeds of 100 Mbps downstream and 50 Mbps upstream or better, and is currently in the standardization process within the 3GPP, the standards-setting organization for W-CDMA.

  • [5] Nokia Siemens Networks

    Nokia Siemens Networks is a leading global enabler of communications services, providing core network solutions to some 600 carriers serving a combined 1 billion customers worldwide. The company is headquartered in Espoo, Finland.
