But, the development of the third generation mobile communication is not smooth, because of the technology is not maturity, many countries are in the process of using all sorts of problems. According to their experience in the development of the third generation mobile communication, how to from the second generation of mobile communication smooth transition to the third generation mobile communication is vital. The graduation design mainly is to analyze the related technologies and the development of the third generation mobile communication, and discusses its smooth transition. keywords: the third generation mobile communication smooth t
