In2008, the Ministry of industry and information technology under theguidance of the communications industry, Chinese completed second reconstruction. China Telecom as capital is110000000000yuan RMB, the successful acquisition of the original China Unicom’s CDMA mobile communicationnetwork and the network users. Since then, China Telecom owned his first mobile operating licence.From the acquisition of early nearly30000000users, which lasted fiveyears mastermind with painstaking effort to the current nearly150000000users, China Telecom traversed an extraordinary path of development. Has made such a gratifying achievements, and large-scale capital investment and equipment renewal is inseparable. At the same time, network optimization hasplayed a crucial role in. In the premise of the market operation cost pressurebig, how to solve the larger problem in the limited funds, the mobile communication network more stable, give users perceive better every China Telecommanagers must consider the problem. This paper demonstrates the optimization of CDMA1X and EVDO networks from the following points.1, through the process of the development of CDMA technology and experience of technical innovation as the research foundation, summarized the development process of CDMA.2, the CDMA1X network system structure, interface types and important element are introduced. The1X traffic in the dropping rate and frame error rate,transmission of data loading, data business, analysis of resource use data related business, find the key point to influence the performance of the system.At the same time, put forward suggestions for optimizing the system networkto optimize the use of existing equipment. This paper states the importanceof1X network optimization, the focus is to optimize the analysis research to the PN code optimization strategy, optimization strategy of adjacent intervaland EVDO optimization.3, the implementation of optimization scheme, in the practical application ofthe calibration scheme, through actual examples of system engineering, analysis of the reasons can affect the network performance in actual system in engineering. At the same time, through the test of power transceiver, pilot pollution, congestion, carrier to interference ratio of the system optimization. According to the optimization of the system behind the conclusion, the concentration of1X voice traffic of area network, research on system optimization ofrelated key parameters affecting the process of system network. In addition,with the carrier frequency, data rate, capacity limit, DO overload parametermodification technology across frequency refers to the system in this paper,to optimize technology in operation, accurate application to enhance the research task of this paper, through the actual operation results show that the optimization scheme of this paper is to improve the stability of the system, optimization the existing system, improve the quality of service.This paper details the development course, China Telecom CDMA mobile communication network technology, effect and benefit and importanceand to optimize the network in daily operation after the. Analysis of the current operation status, to maintain the existing system equipment standard optimizing system performance, to meet the higher, more extensive user needs.
