Embodiment Construction

[0057] The present invention proposes a method and system for wireless signal coverage analysis, wherein the collection server automatically collects, summarizes and analyzes the original compressed CDR generated by the BSC. The analysis server calculates the latitude and longitude of each call record, executes the judgment criteria of pilot pollution and weak coverage, and displays the data geographically.

[0058] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0059] figure 1 It is a schematic structural diagram of a system for wireless signal coverage analysis in the present invention, the system includes an acquisition server and an analysis server.

[0060] The acquisition server downloads the original CHR file, parses the original CHR file into a CHR plaintext file, and extracts the data field information required by the analysis server to analyze weak coverage and pilot pollution from the parsed CHR plai...

Abstract

The invention provides a method and a system for performing wireless signal coverage analysis. An acquisition server downloads a CHR file and analyzes the CHR file into a CHR plaintext file, extracts data field information, required for weak coverage and pilot pollution analysis by an analysis server, from the CHR plaintext file, and converts the data field information into a format which can be identified by the analysis server; the analysis server calculates the longitude and latitude of a terminal corresponding to each call record according to the CHR plaintext file and base station information; and the analysis server rasterizes a vector map, determines the position of each call terminal according to the longitude and latitude of the terminal, groups the terminals into grids, and analyzes the pilot strength, the Ec/Io and the pilot number when the call of a terminal in each grid is accessed so as to determine whether a corresponding area in the grid is a weak coverage and/or pilot pollution area or not. By adopting the method and the system of the invention, the problems of complicated artificial analysis steps, heavy workload, low efficiency, incapability of geographic display, and the like in CDR analysis work are solved.

Description

technical field [0001] The invention relates to the field of data analysis of mobile communication systems, in particular to a method and system for wireless signal coverage analysis. Background technique [0002] CDR (Call Detail Record, call detail record data) is the user call detail record data automatically generated by the BSC (Base Station Controller, base station controller) in the wireless communication BSS (Base Station Subsystem, base station subsystem). Important information such as wireless signal status, base station resource occupancy, business type, frame error rate and other important information during a call. These information are classified and recorded by more than 600 fields. Wireless network operators can conduct combined analysis based on these fields to find out the user Key information required for network optimization such as the voice quality of a call, the used sector, and wireless signal strength, and accurately find weak coverage and pilot poll...
