Base station positioning method and device based on crowdsourcing data, equipment and medium

Abstract

The invention relates to a base station positioning method and device based on crowdsourcing data, equipment and a medium, and belongs to the technical field of communication positioning. The method comprises the following steps: taking communication data of each terminal and a base station as observation data, taking self positioning information of each terminal as crowdsourcing data, then carrying out grid division, and carrying out extended Kalman filtering positioning considering a non-line-of-sight error by using a data grid to obtain a first positioning result; according to the method, the non-line-of-sight error is determined to improve the base station positioning, especially the positioning accuracy in a city, the second positioning result is obtained by performing factor graph optimization-based positioning through the data grid, the historical observation data is fully utilized to suppress the influence of abnormal data on the positioning result in the base station positioning process, the base station positioning accuracy is improved, and the positioning accuracy of the base station is improved. And finally, the target base station is positioned according to the first and second positioning results. The method is completed based on crowdsourcing data, an operator charging base station database does not need to be adopted, the positioning accuracy is high, and low-cost accurate positioning of the base station is achieved.
