Embodiment Construction

[0037] The prediction area division method based on the transmission loss of the drive test data designed in the embodiment of the present invention divides the large-area prediction area into the following division rules according to the test time, cell information and geographical location information of the drive test points in the drive test data. For the sub-region of the wireless signal, the parallel and efficient inversion prediction is realized for the field strength and propagation loss of the wireless signal.

[0038] The drive test data in practical applications is obtained through on-the-spot measurement, and at least includes test time, latitude and longitude of drive test points, received signal strength information, and cell information.

[0039] Table 1 lists the records of a road test data in the actual situation.

Abstract

The invention discloses a prediction area division method and device based on drive test data. The method includes: acquiring several drive test data belonging to the same community; Points are connected; according to several closed sub-regions surrounded by the connection lines of the road test points, the prediction area is determined to solve the problem in the prior art that the effectiveness and accuracy of dividing the prediction area are poor, and the network cannot be effectively controlled. , and the process of manual division is cumbersome, time-consuming, and slow, and it is not suitable for the problem of dividing a large area.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a prediction area division method and device based on drive test data. Background technique [0002] In mobile communication network planning, the quality of network coverage will be directly reflected by the quality of calls, which will affect user experience. Since the control of network coverage depends on the field strength prediction of the wireless signal in the network coverage area, if the field strength prediction of the wireless signal in the network coverage area is to be accurately predicted, the network coverage area needs to be divided first to determine the prediction area. [0003] At present, the field strength prediction methods of wireless signals in mobile communication networks researched at home and abroad include the field strength prediction method based on the statistical prediction model (for example, Aokang model, etc.) A field strength pred...
