A method includes calculating, by a mobile station, a second coordinate according to a first coordinate and a first observation value of a first base station, and a second observation value published by a second base station; and determining, according to the calculated second coordinate, whether there is a deviation in a third coordinate published by the second base station. When there is a deviation in the third coordinate, calculating location information of the mobile station according to the second coordinate and the observation value of the second base station, wherein the first coordinate and the first observation value are information used for calculating the location information of the mobile station before base station is switched. The first base station publishes the coordinate to the mobile station before base station is switched; and the second base station publishes the coordinate to the mobile station after base station is switched.
