Analysis And Optimization Of China Unicom Wcdma Radio Network Performance

With rapid development of the mobile communication technology, due to the emergence of various new business and the increasing number of users of different Chinese telecommunications operator, the network scale have to gradually expand to adapt to the needs of the development of, and this kind of the expanding of network size, would make the communication network face more and more problems and challenges. China unicorn as one of the three major operators, in this kind of development tendency will also be in the face of these new problems. This kind of situation as the network continuously expanding the scale and growing business users, it makes the importance of network optimization and maintenance the become increasingly highlight up.Concerning Unicom, the3G standard takes comparatively mature technology european-backed WCDMA system, WCDMA namely broadband Code Division Multiple Access (CDMA) of Italy, is Wideband Code Division Multiple Access of abbreviation, is the third generation wireless communication technology, it is created by3GPP organizations formulate, in order to GSM MAP as the core, UTRAN as wireless interface of the mobile communication system. For unicorn WCDMA is concerned, analyzes its WCDMA network performance and selecting proper optimization method and optimization tools optimization, for realizing unicorn3G and2G network resources more widely Shared, and improve the system of network resources use efficiency has very realistic significance, at the same time for unicorn3G business further optimization also plays an important role.This paper will be first to expound the development situation of communication technology in the domestic and foreign, at the same time, the3G network technical standards and characteristic will be also discussed. After that, some key technologies of WCDMA are introduced, the key techniques including the baseband processing, rf, intermediate frequency and WCDMA receiver enhancement technique, etc. After analysis of these relevant WCDMA theory technology is expounded, in combination with the specific goal based on network optimization goal request for unicom WCDMA network optimization principle and method to make clear, involves research have unicom business, network coverage and switch between svstem etc.After the research above, this paper will take unicom group business optimization as an example to analyze the packet data service agreement, the structure of the users, and at the same time the common data method will also make corresponding analysis,and then to put forward the different optimization scheme from these problems...
