Mobile communication network optimization,also called the radio network optimization,and wireless network optimal or nets optimal for short, is mainly to maintain or improve the performance of telecom or mobile business. CDMA is one of them, which has many advantages such as the good secrecy, anti-jamming performance and resistance to multipath fading. Based on these features, CDMA technology has been formulated as international technical standards, become the main technology of 3G and so many users can enjoy various CDMA equipment and terminal prooduced by the technical standard, and rapid communication services that CDMA network brought.The network optimization has been done by the union of three parties, mainly through the telecom and the third party cooperation optimization. The contents include network foundation site started, quality improvement, network covering performance optimization, and the user’s actual feeling improving, the customer complaint reducing, to find and solve major problems of network. The purpose focused on optimizing the allocation of resources, and improving the performance of the network and the network of the whole quality of service, assisting shanxi telecom yuncheng branch network to make high-quality goods.Network optimization contains many contents, through the feedback network verification, the alarm track processing, complaint classification, network parameters of verification, and NETMAX data analysis, and relevant optimization, this article makes the high-quality goods network. Mainly aspects are in the following:(1) NetMAX optimization subject; (2) TOPN special optimization; (3) wireless network resources efficiency special optimization; (4) the customer complaint optimization analysis; (5) boundary switching optimization; (6) One way optimization problem; (7) system parameters to adjust; (8) multiple signal carrier optimization; (9) access project optimization; (10) coverage optimization; (11) EVDO optimization, etc.In this paper the achievements of the optimization of the work has two main aspects: first, to improve the performance of the whole net, including voice busy simulation.one voice call, establish the success rate, voice soft handoff success rate, voice soft handoff factor, voice traffic, DO global wireless drops rate of yuncheng EVDO DT test and the average index have been greatly improved; Second, the improvement of the network coverage, through the RF optimization, the cover of yuncheng business indexes higher ascension.Above these work to optimize network the allocation of resources, improve the operation of the network environment, and improve the operation of the network quality, all has the important practical significance.
