The present invention discloses a method for obtaining the direction of a target location through a handset, which includes: the handset obtains geographical information of a current location and that of the target location, determines a geographical meridian line of the current location and a angle of this geographical meridian line displayed on the screen of the handset; the handset determines the direction from the current location to the target location according to geographical information of the current location and that of the target location, determines an included angle between this direction and the geographical meridian line. According to the included angle and that of the geographical meridian line displayed on its screen, the handset determines the direction displayed on the screen of the handset from the current location to the target location, and displays the direction of the target location on the screen according to the displayed direction. The present invention solves the problem that existing handsets cannot provide the direction of the target location for the user. The user can confirm the direction of the target location through the handset.
