Abstract
(EN)
The present invention relates to a 5G-based positioning method and positioning system. The method comprises: a broadcasting step: a 5G base station acquires from a satellite positioning information of the 5G base station, obtains calibration information on the basis of the positioning information, and broadcasts the calibration information to the outside; an initial positioning step: a user terminal acquires from the satellite initial positioning information of the user terminal; a monitoring step: the user terminal accesses the nearest 5G base station in real time, and monitors and acquires the calibration information broadcast by the nearest 5G base station; and a calibration step: the user terminal calibrates, according to the calibration information acquired in the monitoring step, the initial positioning information acquired in the initial positioning step to obtain positioning result information. As described above, according to the present invention, 5G base stations can be used for achieving centimeter-level accuracy positioning, without providing additional CROS base stations and data centers, so that the cost of accurate positioning is reduced.

La présente invention concerne un procédé de positionnement basé 5G et un système de positionnement. Le procédé comprend les étapes suivantes : une étape de diffusion : une station de base 5G obtient à partir du satellite des informations de positionnement de la station de base 5G, obtient des informations d'étalonnage sur la base des informations de positionnement, et diffuse les informations d'étalonnage vers l'extérieur ; une étape de positionnement initial : un terminal utilisateur obtient à partir du satellite des informations de positionnement initial du terminal utilisateur ; une étape de surveillance : le terminal utilisateur accède à la station de base 5G la plus proche en temps réel, et surveille et obtient les informations d'étalonnage diffusées par la station de base 5G la plus proche ; et une étape d'étalonnage : le terminal utilisateur calibre, selon les informations d'étalonnage obtenues à l'étape de surveillance, les informations de positionnement initiales obtenues à l'étape de positionnement initial pour obtenir des informations de résultat de positionnement. Comme décrit précédemment, selon la présente invention, des stations de base 5G peuvent être utilisées pour obtenir un positionnement de précision au niveau du centimètre, sans fournir de stations de base CROS supplémentaires et de centres de données, de telle sorte que le coût de positionnement précis est réduit.
