Abstract


The rapid development of science and technology has brought rapid changes to people's lives , advances in communication technology have had a profound impact on social civilization and progress . The emergence of the concept of personal communication for future communication services show a bright future , and its development will enable mankind into a new \As a hot spot in recent years the development of third-generation mobile communication systems (3G) has received international attention , and is one of the most important direction of development of the field of communication in the early 21st century . The third generation mobile communication system is a relatively first , second generation mobile communication system more advanced mobile communication system . Its highest goal is to make the individual end-user at any time , anywhere , with anyone through any means to achieve high quality transfer of any information . International Telecommunication Union ( ITU International Telecommunications Union ) has been committed to the standardization of the third generation mobile communication system formulation and selected from various manufacturers and research institutions submitted 10 wireless transmission technology , Europe 's CDMA' dissertation">WCDMA, North America CDMA2000 and China 's TD-SCDMA 3G technology , WCDMA technology is a wireless technology is the most mature and most widely used communication technology . The paper first introduces the background and current status of the WCDMA radio interface structure of the WCDMA system carried out a careful analysis of WCDMA network air interface for high-speed packet service processing , combined with the results obtained from studies Unicom WCDMA network - specific applications a set of packet radio service to optimize the treatment process and a set of basic data on the air interface layers and various parameters . Verified by experiment optimization and application of the actual work on the air interface and high - speed packet service .
