Abstract

The embodiment of the invention discloses a calibration method and device of a coverage database. The method of the embodiment of the invention comprises the following steps: a measurement control message is sent to a terminal in a network coverage area, and the measurement control message is the information indicating the geographic position of the terminal which is carried by the terminal supporting a global positioning system (GPS) in a reported measurement report; the measurement report sent by the terminal is received; and if the measurement report contains signal strength and the geographic position information, the district signal strength and the geographic position information of the terminal are stored in the coverage database. With the scheme disclosed by the invention, the calibration time and the calibration cost are reduced, and the positioning technology is convenient to apply and popularize.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a calibration method and device for covering a database. Background technique [0002] In the cellular wireless communication system (such as GSM, UMTS), in order to make some applications possible for network-side devices, some positioning methods have emerged. These applications include: traffic distribution, user behavior analysis, coverage analysis, problem location, etc. A positioning method based on Measurement Report (MR) is one of them. [0003] In a cellular network, a terminal can usually receive signals from multiple surrounding cells at one point. A basic assumption of the MR-based positioning method is that the combination of the strengths of the signals received from different cells at each geographical point is unique. Then, the location of each point in the network coverage area and the received signal strength of different cells can form a database...
