The invention provides a method for applying drive test data to the propagation model tuning, which comprises: step 1, obtaining the original drive test data; step 2, selecting the data satisfying the preset conditions, as valid drive test data, from the original drive test data; step 3, extracting the valid drive test data to form a data file for the propagation model tuning. The invention also provides a device for applying drive test data to the propagation model tuning, which comprises a drive test data acquisition module adapted to obtain the drive test data from a region to be tuned; a valid drive test data generation module adapted to generate valid drive test data from the drive test data based on the preset conditions; and a data file generation module adapted to extract the valid drive test data to generate a data file for the propagation model tuning. Based on the test data of the existing network, the invention can greatly reduce the test operation of CW, save the cost of network construction, and ensure that the tuned model can accurately show the local propagation characteristics, thereby optimizing the configuration of base station.
