Abstract

The invention discloses a method and system for obtaining and correcting radio propagation model parameter, which is applied to treat DT data in existing mobile communication system, comprising a data reading module for finishing format identification and reading of base station information and DT data; a data processing module for identifying and sieving sector data points, deleting special datapoints and processing data calculated by a special algorithm; a data output module for ranking propagation environments and finishing specified format data conversion and output; a propagation model correcting module for correcting the propagation model. The invention solves the inconvenient problems that present CW field density test needs much manpower and material resources, takes time, has low efficiency in practical operation for obtaining and correcting radio propagation model parameter.

Description

technical field [0001] The invention relates to a method and a system for processing DT (Drive Test) data in a mobile communication system, acquiring and correcting wireless propagation model parameters. Background technique [0002] In the network planning and optimization of mobile communication systems, the wireless propagation model is the basis of its design, but usually standard propagation models such as Hata, COST231 and other models cannot accurately reflect the local propagation characteristics, affecting the quality and accuracy of planning, design and optimization. sex. Such as figure 1 As shown, it is necessary to carry out CW (Continuous Wave) field strength test for this purpose, and correct the propagation model with the test data. The CW field strength test needs to set up a dedicated CW transmitter to simulate the emission of the base station, and at the same time use the supporting receiver to collect test data points; this test is mainly used for propag...
