Abstract: A mobile terminal collects information items identified by a user of the mobile terminal, the collected information items having different formats of data that are to be rendered by different applications at the mobile terminal. The mobile terminal synchronizes itself with the remote server so that the user can access the plurality of information items stored at the remote server from another terminal. Next, the mobile terminal displays some information items in a chronological order. In response to detecting a user selection of one information item, the mobile terminal determines whether data associated with the information item is in the mobile terminal or not. If the data is present in the mobile terminal, the mobile terminal then renders the data on the mobile terminal. Otherwise, the mobile terminal first downloads the data from the remote server and then renders the data on the mobile terminal.

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.
