Abstract
The present invention discloses a positioning method, including: acquiring, by a mobile terminal, a location of the mobile terminal in open space; determining, by the mobile terminal according to the location of the mobile terminal in the open space, first closed space that corresponds to the location of the mobile terminal in the open space and in which a closed positioning service is provided; and performing, by the mobile terminal after determining the first closed space, closed positioning for the mobile terminal by using a closed positioning program and map data. The method of the present invention enables a mobile terminal to automatically perform closed positioning without the need to artificially identify closed space in which the mobile terminal is located and search for a corresponding closed positioning program, and therefore provides convenience for a user and can improve accuracy of closed positioning.
