Abstract: A GPS positioning method for a mobile terminal, and a mobile terminal are provided. 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 identifier 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 of the mobile terminal.
