PHS Wireless Network Optimization Of The Jilin City

Network Optimization is an important component of maintenance work for mobile communication. Its effect determines the service quality of network and brings far-reaching influence on the development of the business market directly. PHS system adopts the structure of little honeycomb and slight honeycomb, so it brings certain degree of difficulty to the planning and optimization of the network. At the same time the technological characteristic of PHs determines Network Optimization is a long-term and challenging work.In this thesis, setting out form the introduction of the development of mobile communication system and commercial application of PHS in China, we firstly described the basic knowledge of PHS. And then, according to the system characteristic analysis and fulfillment in the work experience, we summarized the thought of the net work optimization and proposed various kinks of problem analytical methods. Especially we carried on an overall analysis to the serious phenomena in chapter6 of this thesis, such as tele-traffic jam and wireless interference, appeared in PHS network. At the same time, we put forward the effective methods of solving the problems of wireless covering, capacity and interference in PHS network. Finally the surviving prospect and further development of PHS technology had been discussed.In a broad sense, all help to improve the quality of the PHS network engineering activities can be defined as network optimization activities. Put into operation on the PHS wireless network parameters collection and data analysis, find out the impact of the quality of wireless networks, through technical means to adjust the parameters or make the best wireless network running.In this paper, the wireless network optimization classified a total of four categories: to maintain excellent network category, type of network failures excellent, excellent network engineering, network-type system better and better in all types of network attention on the issues; for this article Wireless networks to assess the indicators, wireless network optimization methods were carried out of the system, wireless network optimization process of analysis, in day-to-day wireless network optimization process, the user can be a reflection of complaints, data and the way Huawutongji Measured, and other problems. Once a traffic fail indicator, decreased quality of the wireless network or to reflect the user to concentrate more, should be in time for the wireless network optimization.Wireless network optimization of the new technologies are adaptive antenna technology, high-sensitivity receiver technology, SDMA technology; network operators affected by the quality of the factors in the following areas: side of the base station layout irrational installation, call irrational division of zone, traffic The uneven burden, the frequency of conflict resources, equipment, such as job insecurity. Based on the wireless network optimization projects, the development of the network will generally be divided into three phases, for different stages of wireless network optimization side of a different focus. In the early opening of the system, with a focus on optimizing the coverage; in the pre-operating system, with a focus on optimizing traffic; in the latter part of operating system, with a focus on resource optimization frequency.In this paper, the on-site testing methods were studied. Network operators to accurately understand the actual situation must be tested regularly to the site, mainly to test the indoor and outdoor base stations, network coverage, in the air simultaneously, and call quality. At the beginning of testing before the first test to exclude the regional base of the fault lines and cut power to resolve such issues to ensure the normal operation of the base station. Network operators test the quality standards are synchronized, covering wireless Rate incoming side, the side of the wire through rate, the busy traffic base stations, base station channel availability, PA division, and other content.PHS network of large-scale construction period has been basically completed, the network has entered a comprehensive maintenance and optimization of the stage. PHS for the technical characteristics of the current PHS network bottlenecks and optimize the focus on the wireless side. With the growing volume of users and the overall value-added business applications, wireless network side under increasing pressure, how to make use of limited resources, wireless, wireless network to provide excellent services to optimize the PHS networks priority projects. In order to optimize the network theory applied to practice, verify reasonableness of the City of the examples in this article analyzed. Way through the on-site testing, data analysis, testing and call simultaneous response to the designated test area network status quo, and to make scientific and rational adjustment of the network optimization program, to enhance the quality of the network, at the same time establish the customer's brand image and improve customer satisfaction. Through the detailed survey and analysis of the test, compared with the overall good network coverage, but the individual regions to set up base stations because of the unreasonable position, around the base of a certain degree of signal interference caused by signals of individual regions compared with chaos, not master Using signals in the call, frequent switching, leading to dropped calls. To solve these problems, our individual regional base for the restructuring and reform.Network optimization is a long-term, complex, step-by-step process, starting from the day-to-day maintenance should focus on the following aspects: the base station to update and improve the database. Base is a database network optimization and maintenance basis, it is necessary to ensure the accuracy of the information base and timeliness; day-to-day inspection equipment alarm. Key Inspection base line fault, E1 fault, strong back, and other important warning should be classified analysis of the reasons for exclusion in a timely manner; day-to-day situation of simultaneous inspection; day-to-day network traffic to track the data. In this paper, the PHS to 3G smooth transition of the program was discussed. Although the technical system on the two products vary, but can layer in the network equipment business, the core network and terminals to take on the integration of different positions or strategies to maximize the reuse of existing PHS network PHS and 3G co-exist in harmony with softswitch-based next-generation networks. Overall, 3G and PHS are two different levels of technology, 3G because of a higher frequency efficiency, greater capacity, better quality and business, PHS will have an impact on the development. However, PHS will continue to improve, such as the development of a richer and business applications.Through the wireless network optimization theory and practical combination, in Jilin City on a wireless network is optimized. After nearly two years of constant improvement of the City's current wireless network quality has improved. Due to complicated and ever-changing situation on the ground, some theoretical calculations and there is still a real difference, but the overall effect of significantly more optimization. After practice, overcome many difficulties, and finally enhance the quality of the network, users have been generally recognized. The research of this thesis provided a heuristic case, in which many difficulties in wireless network optimizations had been settled. It carried on effective try to enlarge the wireless capacity by the method of reducing various wireless interference. In this thesis, the thought of network optimization also had realistic meaning to other mobile communications.
