Abstract: In a multi-application IC card system which is loaded with a plurality of applications and is provided with a platform allowing deletion of the applications, the platform (1) contains an AID control table for controlling the correspondence between each application and its application identifier (AID), and the change of each AID is conducted by rewriting the corresponding AID in the AID control table. Alternatively, the platform (1) has a function of applying an alias AID in addition to the application identifier (AID) assigned to each application and controls the correspondence among each application, its AID, and its alias AID by using an AID control table.

Abstract: The remote control system utilizes a mobile communication terminals 20, the IC card 201 a the mobile communication network to remotely control home-electronics information terminals 11 to 15, 19, 40. In an automatic control mode, when it is detected that the user's mobile communication terminal 20 is moved from the cell area EL where the house is to the neighboring area CR, the mobile communication terminal commands the change of the specific home-electronics information terminal to Going-out status. When it is detected that the user's mobile communication terminal 20 is moved from the neighboring area CR to the cell area EL, the mobile communication terminal commands the change of the specific home-electronics information terminal to Staying status. In such a system, the user can deliberately issue control command in the manual mode.
