METHOD FOR CONSTRUCTING VERTICAL POSITIONING MODEL, AND VERTICAL POSITIONING METHOD AND DEVICE

摘要

Embodiments of this application disclose a method for constructing a vertical positioning model, to enable a network device to obtain vertical information of a mobile terminal based on a vertical positioning model, thereby improving efficiency of obtaining the vertical information of the mobile terminal by the network device. The method in the embodiments of this application includes: determining, in measurement reports MRs of a mobile terminal, a signature feature of measurement report call information MRCALL, where the signature feature of the MRCALL is proportions of appearance of cells in one call of the mobile terminal; obtaining a round test signature feature of a target building, where the round test signature feature is proportions of the cells in the target building, and location information of the target building corresponds to information about a current location of the mobile terminal; and constructing a vertical positioning model based on the signature feature of the MRCALL, the round test signature feature, and height information of the target building, where the vertical positioning model is used to measure vertical information of a target mobile terminal.
