Xuancheng Unicom Optimization Of 2g/3g Interoperability

Now construction of network is just beginning, 3G network of Xuancheng Unicom is still not perfect, so it needs to make up for 2G networks. The purpose of this study is to improve the quality of Xuancheng Unicorn's 3G network by the optimization of 2G/3G interoperability. Unicorn's 3G network is currently operating a short time, the optimization of 2G/3G interoperability is not mature enough, this article describes the technical characteristics of 3G networks and the status of Xuancheng Unicom network, focusing on theoretical knowledge of 2G/3G interoperability, including theory of reselect and handover in the idle state and traffic state. This acticle Carries out the theoretical study to optimize 2G/3G interoperability of Xuancheng Unicom. Practical optimization work includes two parts:engineering optimization and performance optimization. in engineering optimization the optimization of the wireless environment, adjacent relationship optimization, parameter optimization will be detailed; performance optimization introduces key performance indicators, failure analysis, signaling analysis and associated with log analysis. In the actual optimization this study illustrates two methods of optimization, project of implementation by some typical cases. the optimization fo 2G/3G nteroperability has been completed, with very good results, and achieves the research purpose of this paper to improve the quality of the network...
