Abstract: A vertical positioning method provides a server receives measurement report MR information sent by a base station, where the MR information is reported by a terminal device and obtains engineering parameters of the base station based on the MR information, where the engineering parameters include a cell site height, a base station downtilt, and an antenna azimuth of the base station. The server extracts feature information of the terminal device from the MR information and inputs the feature information of the terminal device and the engineering parameters of the base station into a preset artificial intelligence AI model to predict a first height of the terminal device. The AI model is obtained through training by using engineering parameters of a plurality of base stations and feature information of a plurality of terminal devices as input samples and using a preset height as a label.

Abstract: A positioning method relating to the field of communications technologies includes: a positioning device obtains a positioning parameter set and sends the positioning parameter set to a positioning center, where the positioning parameter set includes multipath information of a to-be-positioned terminal, and the multipath information is used to position the to-be-positioned terminal. The positioning center may position the to-be-positioned terminal by using the multipath information of the to-be-positioned terminal.
