Abstract

The invention provides a positioning method by utilizing a base station. The positioning method comprises following information: in a mobile communication network, a server receives wireless network environment information of a positioning communication device in the mobile communication network through the positioning communication device or a serving cell of the positioning communication device, and the wireless network environment information comprises coordinates of cells and receiving power of cell transmitting signals in the positioning communication device; the cell comprises the serving cell and at least one adjacent cell of the positioning communication device; the server uses the wireless network environment information and estimates a position of the positioning communication device. According to the positioning method by utilizing the base state provided by the invention, overevaluation and lack of evaluation of the cell coordinates for positioning can be prevented, and accuracy of the base station positioning can be improved in a stable manner.

Description

technical field [0001] The present invention relates to a positioning method, in particular to a positioning method using a base station. Background technique [0002] In recent years, with the diversification and popularization of wireless transmission technology, positioning methods have also become diversified, and are no longer limited to the traditional GPS (Global Positioning System) global satellite positioning method. At present, other common positioning methods include mobile communication network base station positioning method (base station positioning method for short), WIFI hotspot positioning method and RFID sensor positioning method. The accuracy and coverage of each positioning method are different, and have different applications. [0003] In the RFID sensor positioning method, the coverage of a single sensor varies with the frequency band used, generally within tens of centimeters to several meters, so its coverage is relatively narrow, but the accuracy I...
