Interworking between telephone network and multimedia communications network

摘要

Rapid growth of the Internet and mobile communications networks shows a shape contrast to the nearly saturated telephone network in Japan. We analyze the features of these networks from the viewpoints of the communication time, expansion, representation of information and user age groups. Based on this analysis, we discuss the future interworking and develpoment of these two types of communications. Identifying the network functions which are required to realize the near-future network, we propose a new network system configuration.
