Introduction of IP-based core network in 3rd generation mobile system and future trends

摘要

This paper describes NTT DoCoMo's plan to incorporate IP technology in mobile networks. NTT DoCoMo's position is based on current demand and future forecasts for growth in data traffic. Based on core strategies including multimedia, ubiquity and globalization, data traffic demand is expected to by 2010 grow to about 70 times current levels. For that reason, through adoption of IP technology for the core network and access segments as early as possible, realization of a high speed, reduced cost network is attempted.
