Abstract: The disclosure provides a method and device for processing wallpaper. The method comprises: acquiring the position information of a mobile terminal; judging whether to replace wallpaper displayed by the mobile terminal with a content corresponding to preset position information or not according to the acquired position information and the preset position information; and displaying the content corresponding to the preset position information as the wallpaper based on that a judgment result is positive. By the disclosure, the problem of poor user experience when a user of the mobile terminal uses the wallpaper or a theme in the prior art is solved, and effects of automatically replacing the wallpaper and meeting diversified and personalized requirements of the user are further achieved.

Abstract: The present invention provides a system, method and terminal for communication between WAPI terminals, and the method includes: a calling terminal that has a WAPI function sending a WAPI link establishment request to a called terminal that has a WAPI function, and establishing a WAPI link with the called terminal, the calling terminal communicating with the called terminal directly through the established WAPI link. Using the technical scheme according to the present invention, the direct communication between the WAPI terminals can be realized, and the technical scheme is easy to implement and can reduce the communication costs, and would not be influenced by the coverage ratio of radio signal of a radio operator, a real-time communication will be realized as long as it is within the application scope of the WAPI.
