Method and apparatus for determining base station wireless field strength overlay area range

Abstract

The invention discloses a method which determines the strong covering area coverage of a base station wireless field. The invention comprises the steps: location points which are corresponding to the latitudes and longitudes of all the base stations are reflected to be a whole base station point set on a plane; the whole base station point set is processed to be subdivision triangulation lattices; the circle center positions of circumcircles of the triangle, which contain the same base station point in the subdivision triangulation lattices, are determined and regions formed by the circle centers being sequentially connected with each other are determined to be a Thiessen polygon region of the base station; the overlap region of the Thiessen polygon region of the base station and the initial circle coverage region is determined and the scope of the overlap region is determined to be the scope of the strong covering area coverage of the base station wireless field. At the same time, the invention also discloses a device which determines the strong covering area coverage of the base station wireless field. By utilizing the invention, the factors of landform and physiognomy are not needed to be considered; the strong covering area coverage of the base station wireless field or a community can be simply and conveniently and fast determined.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for determining the range of a base station wireless field strength coverage area in wireless network planning. Background technique [0002] The wireless field strength coverage area in the mobile communication network refers to the area where services can be provided according to the specified service quality indicators. By understanding the wireless field strength coverage of the entire network in different geographical areas, reference data can be provided for adjusting and improving network service quality, thereby enhancing network operation competitiveness. A commonly used method for predicting the coverage area of ​​a base station's wireless field strength is a method based on a propagation model, such as the Okumura propagation model or the COST-231-Walfish-Ikegami model. Among them, the Okumura propagation model uses the urban area with qua...

Problems solved by technology

The COST-231-Walfish-Ikegami model is suitable for propagation loss prediction in the range of 20m to 5km. It can be used as a macro-cell model or a micro-cell model. However, when making micro-cell coverage predictions, it is necessary to have detailed terrain and geomorphic elements , such as street and building data, cannot use statistical approximations

[0003] The above-mentioned method based on the propagation model predicts the coverage area of ​​the wireless field strength of the base station, and it is necessary to consider the difference in terrain and topography. There are many calculation parameters, the method is complicated, and the efficiency is low. Moreover, the accuracy of the data of various topography and topography is very high. , because the topography is constantly changing, it is difficult to provide high-precision parameter data in reality. The existence of these factors brings great difficulties to network planning.
