Abstract
When location information and a user Identification (ID) is received from a client terminal device of a user X, a grid Y, to which the location information belongs, is determined. The user ID and the location information of the user X is stored in a list of the grid Y. The grid Y is in a grid array obtained by dividing a surface of the earth into the grids and areas of the grids are the same. Users in the grid Y and other grids are searched. The grid Y and the other grids form an N-grid and the grid Y is a center of the N-grid. The users are ranked in an ascending order of distances between the users and the user X. The ranked user IDs and distances between the users and the user X are sent to the client terminal device of the user X.
