网优分析方法（Network optimization analysis method） Network optimization analysis method OMC performance analysis According to the analysis of OMC performance data analysis method is commonly used in daily work and network, is an effective means to assess the performance of the network, through the longitudinal comparison of the same element in different time periods, and comparison between different network elements, can effectively dig out the existing problems in network. In the OMC performance index data, we need to focus on several aspects: call setup success rate, dropping rate, handover success rate, traffic overload, statistics and other data through the tool real-time signaling tracking (obtained Um, A, Abis, PPP and other interface information), business (global observation of business information, is conducive to backtracking problem) and observation station operation information (access to the current number of users, power etc.), alarm information (about fault in the base station). Road measurement and analysis Advantages of road measurement and analysis: Through the analysis of road test signals covering the entire coverage area of 1. road test, and test data analysis software statistics covering effect of the overall network of road, which covers the whole evaluation of the network, to determine whether the network coverage planning and design requirements; 2. this method through the analysis of the road test data processing, which can determine the signal coverage area of good quality, the area in which the signal coverage of poor quality, the test results at a glance, clear and intuitive, help operators grasp optimization as a whole; 3. this method can accurately record in each event in the process of road test (call, switching, dropping etc.) the actual signal occurs, and the corresponding location information for the network optimization engineers to analyze specific issues of network; 4., in the process of road testing, the network operator can directly
