A positioning method includes: obtaining a cell identity of a to-be-positioned terminal; determining at least one neighboring terminal of the to-be-positioned terminal according to the cell identity of the to-be-positioned terminal, where a cell identity of each neighboring terminal of the at least one neighboring terminal is the same as the cell identity of the to-be-positioned terminal; obtaining geomagnetic information of a location of each neighboring terminal of the at least one neighboring terminal and geomagnetic information of a location of the to-be-positioned terminal, to generate a geomagnetic information group of the to-be-positioned terminal; and obtaining, geographic location information of the to-be-positioned terminal.
