The invention discloses a fingerprint database updating method, device and equipment and a computer storage medium, and the method specifically comprises the steps: obtaining measurement report (MR) sample data in a target fingerprint database, the MR sample data comprising at least one piece of MR sample data in a preset time period, each piece of MR sample data comprising terminal position data; determining whether each piece of terminal position data and at least one piece of position data in a first indoor position data set meet a preset relation or not to obtain a determination result, wherein the first indoor position data set is determined by MR sample data associated in advance and preset first indoor position feature information; according to the determination result, adding an indoor / outdoor identifier to the terminal position data of each piece of MR sample data to obtain corresponding MR target data; and updating the target fingerprint database according to the at least one piece of MR target data. According to the embodiment of the invention, the accuracy of the fingerprint data in the fingerprint database can be improved, so that the accuracy of the fingerprint database can be improved.
Description
technical field [0001] The invention belongs to the technical field of big data, and in particular relates to a method, device, equipment and computer storage medium for updating a fingerprint database. Background technique [0002] With the development of science and technology and the improvement of computing power, location-based services based on user terminals are playing an increasingly important role in fields such as advertising, marketing, and emergency rescue. Location service, also known as location service, is a location-related service provided by wireless operators for users. The operator has instruction information for interaction between the user terminal and the base station, which can be used for terminal positioning. In order to more accurately locate a user terminal, currently commonly used methods include a positioning method based on a measurement report (Measurment Report, MR). The measurement report refers to the signal strength measurement report o...
