A new direction of next generation mobile communications research - expansion to the mobile ubiquitous

In the mobile communication world, the 2nd Generation Era was the years when new values were created by the fusion of ??mobile?? and ??the Internet.?? In the 3d Generation Era, multimedia contents and applications became available to the mobile environment. And we are now witnessing the era of mobile multimedia unfolds before our eyes. After this, the ??Ubiquitous?? will arrive. Various objects will come to support communication capabilities. The next generation Era will be the years of the ??Mobile ubiquitous,?? in which the mobile environment and the ubiquitous environment will collaborate and coordinate with each other to create new values. I will talk about the system evolution scenario and about new and extended direction of research. The next generation radio access system will be.a packet base broadband system and will support various environments such as cellular, spot areas and indoor offices. Radio parameters will be adaptively controlled, to realize optimized systems for each different environment. Three major components of the ??mobile ubiquitous?? world are: ubiquitous network terminal or gateway device and mobile network. The ubiquitous network needs the function to re-configure itself dynamically. In the gateway device arena, aggregation functions for collecting real-world information from the ubiquitous network, and a conductor-like function for coordination with the ubiquitous network are required. In the area of mobile networks, research topics include the handling of real-world information collected through ubiquitous networks and reflecting that in dynamic service provisioning. Together with research to enhance the radio access and the network, our goal is to achieve substantial results that will he a foundation for a truly valuable mobile ubiquitous system for the individual and for the society.
