Next-generation mobile-access IP network

The recent growth in the use of the Internet and mobile communications is remarkable. It has resulted in Internet access using mobile communications being positioned to overtake fixed network access. However, the data-transfer capabilities of current mobile communications, which is based mainly on circuit switching for voice, are insufficient for implementing systems to distribute music and maps and particularly for distributing movies, which require higher speed data transfer. The next-generation of mobile communications now being standardized thus takes into account the need for high-speed data transfer. Practical implementation is targeted for 2001. This paper describes an IP access network system that enables high-speed data transfer suitable for the next-generation mobile-communication IP network and that will enable mobile application of push-type services.
