Abstract

When an application activation instruction is input, it is decided whether the application is expected to access a high-level protection resource or low-level protection resource (step S 31 ). If the decision is affirmative, display is done to prompt the user to select whether to permit activation of the application (step S 32 ). When the user inputs an activation permission instruction, the application is activated (steps S 33 to S 36 ). As a result, only when the user permits an application, which is expected to access a high-level protection resource or low-level protection resource, to access a predetermined resource immediately before its execution, the application is executed. Hence, the basic processing part and application can operate in cooperation with each other while limiting access to various kinds of resources by the application in a reasonable range.

         32 . A method for downloading an application to a mobile communications terminal, the terminal comprising one or more resources having access protection, the method comprising:
 instructing the download of the application at the mobile communications terminal;   retrieving information representing whether the application is expected to access the one or more resources having access protection, prior to downloading the application;   determining, in the mobile communications terminal, whether download of the application is permitted based on which of said resources the application is expected to access; and   downloading the application to the mobile communications terminal, if download of the application is permitted.   
     
     
         33 . The method of  claim 32 , wherein
 the step of determining whether download of the application is permitted further comprises   displaying a first selection screen on a display of the mobile communications terminal, the first selection screen displaying information indicating which of the one or more resources the application is expected to access, and   requesting input to permit the downloading of the application.
