| With the improvement of living standards, science and technology. Mobile communication technology has been got rapid development. As the carrier of the mobile communication technology. The intelligent terminal plays an important role in communication technology. One of the most directly, intuitive is the mobile devices. Network environment is good or bad will influence user experience norm like speech quality, Internet speed and download speed. Therefore, the development of communication technology contribute to improving the environment of the network, Optimizing network structure.As the leader of the communications industry, China Mobile provided 4G services firstly, and constantly optimizing the LTE network construction, increasing network coverage, to enhance the user’s perception.The background of this paper is the LTE optimization project by China Mobile in Daqing.with the aid of the implementation and development of China Mobile 4G. evaluating the Network status of Daqing area firstly, including network structure evaluation, covering and interference evaluation, parameters evaluation and network health degree evaluation.According to network status evaluation, combined with network actual demand in Daqing,determining the optimal task and clear target optimization, and puts forward the reasonable optimization scheme.The optimization scheme adopt RF optimization,KPI monitoring and enhance, CSFB optimization three means to optimize the existing LTE network in Daqing area. By using RF optimization to solve the weak coverage, the coverage area, pilot pollution problem; through the KPI monitoring and enhance to optimize the wireless connection rate, dropping rate and handoff success rate, through consistency check means, get good speech quality and then complete the CFSB optimization. Finally, optimizing special background project, achieving network optimization under special scene, providing empirical support for subsequent network optimization... |
