The social and economic development speed are accelerated, so as to promote the updating and application for all kinds of information technology. In the development of Social's, the competition of operators are becoming more and more intense. Adapt to social development, we need to improve the quality of wireless networks. and to improve the quality for wireless networks, we have to do a a-job of optimization. According to technical requirements, wireless network optimization are an adjustment process. Optimized wireless network, its performance, coverage and capacity would be significantly improved. In the gradual development of society, wireless network optimization are facing more and more challenges.

From the technical point of view, the essence of wireless network optimization is to adjust the network antenna feed and equipment, and then improve the wireless network coverage, improve performance and capacity. In the actual optimization work, the technical personnel must use the corresponding equipment. For operators, field testing is an effective method to optimize patrol type, which can meet the need of reality. Technicians use OMC to discover and adjust parameters. According to the characteristics of network operation period, the optimization model is divided into engineering optimization and operational dimension optimization. The object of engineering optimization is large-scale network investment project, such as New project and expansion project. After the completion of the work, the equipment can be put into use. There are several methods in the optimization project, such as Test call quality and road survey coverage area. If the system is put into use, in order to ensure the network quality, for subsequent expansion to lay a good foundation, we need to use engineering optimization methods. Engineering optimization methods do not have large-scale network investment. The purpose of this work is to improve customer awareness to identify possible problems during network usage.

During the optimization of wireless network, the value of quality index and KPI is more important, and the data are collected by means of road measuring equipment, Protocol analyzer and network management system. Based on the analysis and statistics, the optimization software is used to adjust and revise the correlative parameters. After the relevant work procedures are completed, we can summarize the holistic solution, adjust the network according to the whole scheme, and complete the one-time cycle. Based on the development of network technology, there is no definite change in wireless network optimization, but it will reflect the new features of the series. With the continuous expansion of network scale and the rapid development of computer technology, more and more new technologies are gradually applied in wireless network optimization. From the point of view of management, network optimization is to make full use of the existing human, financial and material resources, such as resource organization to achieve the optimization.

The challenges posed by wireless network development. In the time of simulating cellular communication, the optimization of wireless network is to adjust the RF parameters to improve the coverage of wireless network and ensure the security of the system. 2G cellular communication, wireless optimization is mainly reflected in the improvement of wireless coverage, to find a good frequency allocation scheme, so as to improve the frequency of resource utilization, reduce the adjacent frequency and frequency interference. GSM network optimization includes testing coverage, analyzing and collecting data, analyzing network index, wireless traffic statistic analysis, adjusting and optimizing wireless parameter, etc. In the increase of the commercial degree of CDMA network, the network optimization needs new adjustment. CDMA has the concept of soft capacity, resulting in respiration effect. The presence of interference factors can consume network capacity and increase noise level. As a result, the focus of the optimization effort is to select the optimal system capacity to reduce interference. The WCDMA optimization includes the fast power in the control system, the fast control congestion, the link adaptive, the allocation channel and the control load. At the same time, we should adjust network performance on the basis of experience or statistics to realize network optimization.

Under the influence of environmental factors, the commercialization of TD-SCDMA network in China has been continuously improved. TD-SCDMA will introduce the smart antenna, joint detection, relay switching and other technologies, thus providing new requirements for network optimization. According to the actual application situation, the optimization is the scope of the measurement switch, the decision switching threshold exists difference. With the increase of TD-SCDMA frequency bands, indoor attenuation will increase. The key problem is to improve indoor coverage effect and solve the indoor weak cover.

In the open concept of Internet and the concept of telecom closed operation management, IP technology is gradually being used by telecom network technology. In the process of optimizing the wireless network, compared with the traditional voice service, the booming of data business also brings more challenges to the optimization of wireless network. The optimization of wireless network quality can not be limited to coverage, frequency interference and so on, but also the IP of wireless network and business data quality relationship analysis. Later development will pay more attention to the optimization of business level.

Collaborative optimization of wireless network integration. In the gradual increase in operator size, optimization is no longer a simple technical issue. Operators need to operate a variety of cellular wireless networks in a unified time period, thus increasing the difficulty of optimizing wireless network technology. To optimize your wireless network, the scope will become broader. When optimizing different types of wireless networks, the 2G, 3G and 4G networks should be optimized for short distances. But the actual situation is that each operator in the network development, the Optimization personnel training and the quantity existence serious insufficiency phenomenon. And how to use the existing resources to achieve synergy optimization will be an important problem.

With the use of different types of wireless networks, wireless network optimization methods are constantly updated. Optimizing the management of wireless network technology requires constant change.

First, the construction of centralized network optimization support system. For the whole wireless network optimization work, the development of the Optimization support tool has very important significance. In the current development situation, the staff in the overall optimization process of personal habits and work experience accounted for a heavier proportion. Streamline small programs to complete all kinds of ancillary work. The effectiveness of wireless network optimization is largely dependent on the experience and expertise of the optimization staff. For the telecom operation, we should make use of the vast amount of users and business volume to increase profits, so as to reduce human costs and improve profit margins. This will increase network optimization personnel. In the process of increasing network scale, it is necessary to use centralized network to optimize the support system, to rationally make resources and improve the efficiency, so as to realize the standardization and process of work. Modern enterprise attaches importance to IT system. Improve the quality of wireless networks by centralizing network platforms and specialized network optimization tools.

Second, business optimization. Business optimization should be based on customer perceptions. During the 2G Cellular network operation, the user provides the digital voice service, through the network index to judge the feasibility of network optimization. In the continuous development of the business, telecom network users of the business needs of a variety of characteristics. It is difficult to achieve the actual effect by relying solely on network metrics to measure the optimization of wireless networks. The data business group forwarding characteristic, the user's actual feeling is unsatisfactory. At this point we need to optimize the business based on customer perceptions. To improve the quality of the whole network, the customer's actual perception as an optimized guide can be used to help the operators to discover the product problems on the side of the terminals and the network side during optimization.

Optimize the wireless network, face more challenges. From the technical level, the key technologies used in the network can promote the optimization of the network and the actual production of the integration, in order to improve the overall quality of wireless networks.
