US 7,406,332 B1 · Radiotelephone terminal with chip card provided with browser

Abstract

This invention improves the intelligence of chip cards (SIM) in mobile radiotelephone terminals, so that a subscriber may, through the terminal, easily access databases (DB), attached to a server of services (SV). It facilitates the dialog between a subscriber who owns a mobile radiotelephone terminal and a server of services through the medium of an exchange of request and response messages. The card comprises a browser (NV) which interacts with the server and which can be triggered by selection in the mobile terminal or remotely by the server. The card and the server exchange short messages. Libraries of supplementary functions (BI), stored in the card, can be triggered by the server through the browser. The invention also relates to communications between the card that is equipped with the browser and the server.
