Intelligent Location Of Uplink Interference Based On Wireless Statistics Check System

With the rapid development of technology, the improvement of people’s living standard, and the acceleration of life rhythm, mobile communication has been closely interrelated to daily life. With the soaring number of mobile users, expanding the scale of the mobile communication network, and increasingly complex structure of communication systems, mobile operators pay much more attention to the quality of mobile network service. However, due to the open environment in which radio wave transmits, it is liable to be influenced by outside interference. It is the main content of daily radio network optimization to solve the problem of network interference.Uplink interference is one main reason for descent of communication quality. It directly affects KPI, including the wireless coverage, connection rate, rate of dropped calls, rate of channel availability, etc. Previous uplink interference location is not only complex, but also highly inefficient and a waste of time, it is an important reason for influencing network quality and performance. Solving the problem of uplink interference has become the key point of wireless network optimization. In according to an idea of theoretical analysis, feature extraction, algorithm formation and instance test, I study the principle of varieties of uplink interference, combined with FAS statistics, and then propose uplink interference intelligent location based on template matching algorithm.Firstly, I start from the theoretical study of uplink interference in GSM wireless network, deeply analysis varieties of uplink interference principle, propose the interference model. I comprehensively analyze the FAS statistics collected from OSS system, exploit its interference information and characteristic, and get the standard diagram of all types of interference. Secondly, I extract uplink interference map from wireless statistics reader system, use the classic template matching algorithm based on pixel gray value matching algorithm to match the interference map with standard diagram then get the type of interference map. Finally, I verify the accuracy of intelligent location of uplink interference with actual case.To sum up, intelligent location of uplink interference can achieve real-time analysis and monitor uplink interference of the all cells. It improves investigation efficiency and location accuracy and saves a lot of manpower and material resources, which has a preferable practicability and promising application prospects.
