6 Seamless Networking Technologies 6-1 Overview of Research and Development on Seamless Networking Technologies

National Institute of Information and Communications Technology of Japan (NICT) completed a project on new-generation mobile communications networks for beyond 3G or 4G in March 2006. This paper presents our vision of new-generation mobile communications networks from networking perspective and their capabilities to be offered: fast and large-capacity handover, cross-network handover, cross-device handover, and interworking between real and cyber worlds. Then, Metro Mobile Ring network technology for the first capability, MIRAI architecture for the second and third capabilities, and other works are presented.
