Embodiments of the present invention provide a GPS positioning method for a mobile terminal, and a mobile terminal. The method includes: after GPS positioning is started, acquiring a first cell identifier of a first cell in which the mobile terminal is located; acquiring, according to the first cell identifier, first latitude and longitude information corresponding to the first cell from a correspondence table stored on the mobile terminal, where the correspondence table includes a cell identifier and latitude and longitude information corresponding to the cell identifier; and with reference to the first latitude and longitude information, and time information and ephemeris information that are acquired in advance, performing GPS positioning on the mobile terminal by using a GPS receiver in the mobile terminal. According to the embodiments of the present invention, when the mobile terminal performs GPS positioning, latitude and longitude information corresponding to a cell in which the mobile terminal is currently located is acquired from a correspondence table stored on the mobile terminal, and a speed at which a GPS receiver performs the GPS positioning may be increased according to the latitude and longitude information, and time information and ephemeris information that are obtained in advance.
