The Study Of Optimization For Load Balancers In The GSM And WCDMA Mobile Communications Netword

The first generation of mobile communication system in the early 1980s, which began commercial use is frequency division multiple access communication system, belong to analogue cellular system. Mobile communications second generation system began in the 1990s after, it used TDMA or the communication system, belong to CDMA digital cellular system. In order to realize human mobile development ultimate goal, ITU proposed in 1985, the third generation mobile communication system concept. China mobile communications consistently high development, to May 2003 mobile users by the end of 2002 to 2.3 billion (2.0661), fixed telephone 2.3 billion (by the end of 2002 2.1442), Internet users 5221 million (by the end of 2002 4829), China mobile users penetration rate is about 16.3%respectively.With communication technology development, how to make better use of network resources, optimize network structure itself, to provide better network quality, make the network moments in the best state is very important. Network optimization work also mainly divided into the wireless network optimization and core network optimization two aspects. Core network optimization aims to improve its mobile network operation quality and network operating indexes at the same time, in order to improve users'perception as the foundation, pay more attention to in solving end-to-end network and service network Settings, enhancing the rationality, the promotion network resources utilization, eliminate hidden dangers and reduce network operation risk, improve end-to-end network and service quality, enhance network meet the future of new technology and new business development capability,In the article.we first introduces the mobile communication system the current development situation, and introduces the GSM nets and WCDMA network basic network structure and development of the basic situation and GSM network to 3G network evolution process. Then puts forward corresponding core network optimization goal, and the methods and optimization process. Through the systematic research core network narrowband 7 signaling and WCDMA network signaling, puts forward the core network optimization based on the optimization of signaling when analytical methods and measures, and the parameters optimization aspects were introduced, and summarizes some core network optimization experience. On the basis of the core R4 version now network analysis of the current situation, combine JiLin Unicom currently R4 version core network,based on our web traffic and user cellphone registration Internet process studies, and puts forward the GSM. WCDMA two nets load equilibrium optimization idea, and passed the now nets actually test, completed this topic research.Through these work to the core network optimization network resource allocation, improve the network operation environment and the network operation quality, satisfying customers' business requirements, all has the important practical significance.
