Strategy for KDDI’s next generation network

In this paper, KDDIpsilas vision and strategy for realizing so-called next generation network is presented. We announced ldquoultra 3Grdquo concept as a fixed-mobile converged network, which is built through a natural migration/extension process rather than building brand new NGN system. Our ldquoultra 3Grdquo network will enable customers to enjoy the real FMBC services, such as the high speed data services and high quality multimedia services whenever and wherever without awareness of the access network or complicated handover operations. Recent topics of our Ultra 3G such as new global submarine cable systems and WiMAX are reviewed. Future photonic technologies for realizing ultra-broadband network will also be addressed.
