The Research Of Evalution Method Of Mobile Network Service Quality Based On Signaling Analysis

In the mobile communication network operation and maintenance work, the network optimization plays a decisive role. From the moment the completion of the network since the beginning of the network optimization. It contains many aspects, such as wireless network optimization, core optimization, transport optimization. With the advancement of mobile network technology is constantly evolving. Due to the ever-changing network equipment, increasing the number of network users, mobile networks have had huge amounts of data all the time. Features can be said that the era of big data in the mobile communications field reflected most vividly. In this context, data mining technology and network optimization combine emerged. Intelligent network optimization method based on data mining greatly conforms to the trend of the times, more and more prominent role in its network optimization work.This paper relies on China for a local network operators to assess and diagnose project to practical application as a starting point and end point, aims to combine the data mining technology and web-based end-user perception of assessment methods to realize the mobile communication network quality assessment. Through the evaluation of the actual network validation, the network is a scientific assessment of the proposed method, standardized and efficient approach, with practical significance. This paper describes the functions of the various network elements WCDMA network structure, and summarizes the local network assessment, diagnosis and optimization methods, including targeting optimization, classification method selection, evaluation and other diagnostic procedures. Analysis and comparison of KPI-based network performance evaluation and assessment methods KQI based networks. Paper combines the existing network data using data warehouse, data marts and data mining techniques to the local network for the assessment and diagnosis, the paper use PL/SQL, Clementine, and SAS EG existing network tools such as WCDMA network data is analyzed and assessment. For single-pass and voice access delay of two topics, the use of network optimization support system, signaling CDR, through behavioral characteristics, such as prior knowledge of the incident scene and made an assessment of the local network diagnostic analysis methods, improved voice quality, improves the user’s perception is one of the effective methods to locate the problem.
