CDMA2000-1X Performance Analyze Optimization

With the sharp increase of China Unicom subscribers, the problem that how to exchange minimum cost for the best voice service quality becomes key point for communication managers. At the same time, the globe wireless communication markets have developed rapidly during recent years. Not limited in mobile telephony service, the integrated services as data communication and multimedia communication has become a growing trend and R&D hot spot. All of these indicate that the network optimization is becoming more and more important. The CDMA wireless network optimization work is a comprehensive systems engineering, involves the knowledge and the content are extremely numerous and disorderly. If hoped can in the skilled analysis research network have the problem actual in the daily work, the solution difficult, first must study the CDMA technology earnestly the related elementary knowledge, next must grasp the basic analysis method and the analysis method which the CDMA wireless network optimization work uses, simultaneously optimizes regarding the CDMA system daily network saw the frequently asked questions should have the quite comprehensive analysis method. The question which meets to the practical work in carries on processing using these theory knowledge, may achieve the twice the result with half the effort effect.How therefore this article does revolve to improve the CDMA wireless correspondence quality to conduct the research, the prime task summary is as follows:1. This paper introduces the CDMA network's key technology, call flow and air interface firstly, also It explains CDMA network optimization technology and method.2. Through discovering the phenomenons of the Dropped Call, Access Failure, and FER, the concrete analysis of various kinds of situations are brought forward. The resolvent are brought out. Based on resolutions, this paper continually analyzes some correlative cases. 3. This paper analyzes a lot of practice case and TaiYuan CDMA different case based on theoretic. For example, the PCH overload can be reduce by improving the PCH using limitation of SMS. The application of HASH arithmetic can balance the overload of carriers, and improve call service quality.
