Method for estimating location and apparatus using the same

Abstract

A method and apparatus for displaying a map are provided. The method includes receiving user input for displaying a map, receiving location information regarding surrounding apparatus from each of at least one of the surrounding apparatus using short range wireless communication, in response to the user input, and displaying a message indicating that map may not be viewed when the location information is not received from the surrounding apparatus, determining a position estimation area in which the mobile device may be located based on received location information regarding surrounding apparatus and displaying a map on which the position estimation area is indicated when the location information is received from the surrounding apparatus.

What is claimed is: 
     
         1 . A method for displaying a map of a mobile device, comprising:
 receiving user input for displaying a map;   receiving location information regarding surrounding apparatus from each of at least one of the surrounding apparatus using short range wireless communication, in response to the user input; and   displaying a message indicating that map may not be viewed when the location information is not received from the surrounding apparatus, determining a position estimation area in which the mobile device may be located based on received location information regarding surrounding apparatus, and displaying a map on which the position estimation area is indicated when the location information is received from the surrounding apparatus.   
     
     
         2 . The method according to  claim 1 , wherein each of the at least one of surrounding apparatus receives a GPS signal to acquire a corresponding location information. 
     
     
         3 . The method according to  claim 1 , wherein the position estimation area correspond to a circle with a radius of a predetermined distance from the location of a corresponding one of the at least one of surrounding apparatus. 
     
     
         4 . The method according to  claim 3 , wherein the predetermined distance is equal to either a distance between the mobile device and the corresponding one of the at least one of surrounding apparatuses, or half of a distance within which the corresponding one of the at least one of surrounding apparatuses is communicable. 
     
     
         5 . A mobile device, comprising:
 a display;   an input unit to receive user input for displaying a map;   a transceiver to receive location information regarding surrounding apparatus from each of at least one of the surrounding apparatus using short range wireless communication, in response to the user input; and   a processor to control the display to display a message indicating that map may not be viewed when the location information is not received from the surrounding apparatus, to determine a position estimation area in which the mobile device may be located based on received location information regarding surrounding apparatus, and to control the display to display a map on which the position estimation area is indicated when the location information is received from the surrounding apparatus.   
     
     
         6 . The mobile device according to  claim 5 , wherein each of the at least one of surrounding apparatus receives a GPS signal to acquire a corresponding location information. 
     
     
         7 . The mobile device according to  claim 5 , wherein the position estimation area correspond to a circle with a radius of a predetermined distance from the location of a corresponding one of the at least one of surrounding apparatus. 
     
     
         8 . The mobile device according to  claim 7 , wherein the predetermined distance is equal to either a distance between the mobile device and the corresponding one of the at least one of surrounding apparatuses, or half of a distance within which the corresponding one of the at least one of surrounding apparatuses is communicable.
