Abstract

Services provided by optical networks are coming closer to the home in Japan. The growth rate in the number of FTTH users now exceeds that of ADSL users. The increase in FTTH users is expected to be further accelerated since Japanese broadband service has now become the cheapest around the world as shown in ITU Internet Reports 2005. Against this backdrop, NTT set a target of moving 30 million customers to optical access by 2010. Moreover, experimental networks with same function as full-scale next-generation networks (NGN) will be built in greater Tokyo and Osaka areas by the end of this year. In the networks, a lot of NTT's technologies will be verified whether to go into the final NGN. The presentation explains NTT's roadmap for building the NGN. In addition, optical access technologies and functions supporting service cooperation among providers will be focused as the major features of Japan's broadband market.

Abstract

After a long period of circuit oriented communication in fixed and mobile networks, the Internet Protocol is massivly influencing this field of communication. The presentation shows the smooth transition to a new network environment: the so-called Next Generation Network - NGN. The participating standardisation organisation and their roles are explained. An essential part of NGN is the IP Multimedia System – IMS, which provides a horizontal service platform for the unique development of applications available in fixed and mobile networks. The main architedture principles and bulding blocks of IMS are described. To demonstrate the power of IMS some applications are given: IPTV, Voice Box as FMC-service and the upcoming eCommunity services are described in some detail.

Abstract

In Japan, the 3G systems have already aquired the majority of mobile subscribers and many new services/applications are introduced. Also, various broadband wireless systems are developed or under development towards higher and higher bit rates. In this speech, after the review of trends of wireless and wired communication systems, the vision of IMT-Advanced, especially from users' perspective, will be clarified. Then, the "Ultra 3G" Plan of KDDI, the second largest telecommunications carrier in Japan, will be presented. Some related research activities will also be introduced.
