Consideration and research issues for the future generation of mobile communication

With the explosive growth of the mobile communication and the expansion of Internet services, Mobile multimedia services, e.g. more than 2Mb/s, are expected for future mobile communication systems. As 3G is still not sufficient to support future mobile communication strategy and according to the historical indication of a generation revolution once a decade, it is high time to discuss the development of the future generation mobile communication systems. After illuminating the impetus force to driven the 4G research, this paper studies the vision and framework of 4G, describes the adaptability features of terminals, networks and applications in 4G system and proposes some technologies in the design of future mobile communication systems.
