| With the popularity of mobile communication, GSM has become the most full-blown second-generation mobile communication system. The vast majority of mobile operators worldwide have adopted the GSM standard. By 2003 GSM network has been covered nearly 200 countries. There are 450 operators operating GSM networks. The total number has more than 800 million customers. Customers are sharing of 80% of the global mobile users. By 2004, the world's GSM users reached one billion. Meanwhile, along with the opening of GPRS, and to develop, GSM network has been drawn to the flat 2.5G mobile communication systems, and 85% of the GSM mobile operators choose GSM-GPRS-3G's development. According to the European plan, GSM transition to WCDMA, WCDMA is the most mature, but also in the future mainstream third-generation mobile communication system.In recent years, with the rapid development of mobile networks, network quality of service problem has been more and more people's understand. To improve network characteristic, and make better network coverage, operators can not only establish a good image in the eyes of the customer, but also enhance the competitiveness of enterprises for sustainable development of enterprises to provide strong support. Currently, GSM mobile communication network are already quite mature and stable, large-scale expansion has been drawing off.How to make use of existing network resources, to improve the network quality is an enormous economical benefits and momentous issue relating to company development. Many mobile phone operator has taken shape in China, of unprecedented fierce competition, how to run the network to achieve the best operating conditions, to provide users with high-quality network services, network operators have become the primary task of. At the same time, a comprehensive optimization of the accumulated much valuable experience for future construction and optimization of 3G basis. How to rational use and allocation of present-day network equipment, power sources and capabilities to maximize the network average length of service property, improving efficiency. How to make the network in the growing course of events, be able to protect the network quality of service does not to reduce.How to make the network in the growing course of events, to maintain the network quality of service does not decline, so that mobile communication network optimization of mobile communications network operators improve service levels and protect the important work of the content of communication quality. Network optimization is the entire network of resources and development of demand-driven deployment of the situation, to achieve a reasonable target.At the same time, for problems in network operations, such as poor coverage, voice of poor quality, dropped calls, network congestion, switching and low success rate, through the network optimization to solve. Network optimization is a syntheses and difficult systems project in the country. GSM mobile network go into a low building of high-maintenance phase, the network optimization is especially important and imperative. Network peak is a long and complex course of events, run through the whole process of network development. Network optimization problems encountered in all kinds of used, but solutions to these problems are derived from the professional knowledge, understanding, and therefore GSM network structure and various parameters is of the understanding of a direct impact on the effect of network optimization.Network optimization objective is to improve or maintain network quality and network quality is the result of the interplay of various factors, With the optimization of in-depth development and optimization technologies to improve and optimize the network from the current penetration to include market forecasting, network planning, implementation of the project put into operation until the whole cycle of each part.With the rapid growth in the number of users on the GSM mobile communication network, the network continued expansion, GSM900 frequency due to resource constraints, the largest number of users can carry around 40 million, so have been unable to meet the development needs of GSM networks in some areas, have emerged GSM900 frequency band resource constraints, traffic density, such phenomena as excessive .Although the frequency-hopping technology to solve network capacity needs, but does not provide an ideal voice quality. Meanwhile, the 1800 network band width, frequency rich, can better address the traffic needs of large urban areas. However, in the daily work of network optimization, but we are facing difficulties, and the heavy workload, it is cumbersome, resulting from the discovery of problems in the network to solve the problem for a long time, for such a phenomenon of serious impact on the user perceptions .we have put forward the concept of network optimization platform. We must strive to improve network quality and maintain customer loyalty and achieve an even higher market share in the communications business in their daily operations. It has always been an important research subject and the objectives pursued. On the GSM mobile communication system and the newly opened 3G networks, the impact of the indicators on wireless networks are an important factor in customer perception, but the fundamental basis of network quality assessment for operators.Network optimization must proceed from the whole net. we must constantly observe and monitor the entire network operation and various indicators of change, identify failures and troubleshooting, improve network efficiency, so that existing mobile network resources can be best value for money. Road test, CQT testing and quality analysis is in an integral and important part of the network optimization work. Network throughout the life cycle can not be a lack of testing and quality analysis, they can continue to effectively optimize network performance, maintaining customer satisfaction, reduce the loss of the user. In the mobile network quality analysis, we are primarily concerned with the following indicators or condition: dropped calls, congestion, access failure, downlink quality, switch failure, the base station coverage, etc. If we were to find and solve network problems, it must be based on test results, a more in-depth analysis and judgments, but also need some other supporting tools (such as the district maps, statistics, reports, and a variety of mobile network optimization software) to joint Support.GSM mobile network optimization of auxiliary systems sold on the market are a lot, but most of the system software functions are used to extract statistics and GSM mobile networks, wireless systems of indicators, and equipment failure was very poor in the statistical aspects of the system software.Network optimization in the daily faced with various problems, equipment failure, it is a great impact on the entire network, but also has a regional. Therefore, we should first ensure equipment under normal circumstances in the optimization dirty, and tap of other problems in the network: Parameter setting unreasonable, the antenna tilt angle irrational, unreasonable transmission power, frequency points, setting unreasonable, irrational relationship between clinical areas.And then to solve network problems used by network optimization techniques one by one, and gradually improve the network quality. In mobile communication networks, network optimization is not simply short-term jobs, but rather a gradual process. This article is based on equipment failures to find ideas for the design, to design that will help the daily work of network optimization system, we can exclude the first equipment failure caused by network problems used by this system every day, and then the whole network indicators TOPN analysis, for every poor indicator in each indicator to make rectification and reform program. The system choice as a development platform for Windows XP, the system has good stability, high reliability, high integration and user-friendly characteristics, is the more common user system. Others are also compatible with Windows 98, Widows 2000.Visual Basic6.0 will be used in the main development language in the system. VB is a very powerful programming language, with its flexibility and efficiency in development widely in the field of software. The system service program selected in the Visual Basic6.0 to compile the development environment, resource management, program development environment for Visual Basic.NET, therefore the same resource management choice to achieve in this environment.First we made the basic content of network optimization and a description of network optimization method in this paper. GSM network optimization is focus on in-depth study of some of the key issues, including wireless devices, failure network optimization theory. Meanwhile, the article also needs to combine for JiLin Province, China Unicom's existing GSM network conditions, a simple procedure through the charts and an introductory statement to the conclusion in this paper (GSM mobile network optimization software in the real work of the important position in the development of phenomenon). We analysis of network quality through a variety of mobile network optimization software, the joint support, analyze the real problems quickly and effectively that exist in the entire network, so that indicators of the network as a whole can be mounted to a new level. But also can guarantee the quality of network operations, allowing companies to seize the business opportunity. We are the driving position in the competition. And further illustrates the network optimization work each operator importance. |
