Abstract: Provided is a method for steering a terminal cooperating with a secure element in a telecommunication network to the user's home MNO or MVNO. The method includes steps of Detecting (10) a cell ID change in the telecommunication network; Verifying (11) that the terminal is present in another country than his MNO/MVNO; Verifying (12) if the secure element is connected to his MNO/MVNO; Verifying (13) if the cell ID is already memorized in the terminal or the secure element; Clearing the location information files of the secure element and make a Refresh (14) of the secure element; Verifying (15) again if the secure element is connected to the home MNO or MVNO; and G-Storing (16) the cell ID of the current telecommunication network in the terminal or in the secure element with the associated national MNO partner if it has not been previously stored.

Abstract: Provided is a method for attaching a terminal cooperating with a secure element to the network of a MNO of a visited country. The method includes steps of switching a set of files of said secure element to a new value, including a new SUPI, called entity support SUPI; Building at the level of said secure element an entity support SUCI; Routing an attachment request to said support entity with said entity support SUCI; Decrypting in said support entity said entity support SUCI back in said entity support SUPI; and Swapping said support entity SUPI to the SUPI corresponding to the MNO of the home country. If an authentication is performed that is positive, an attachment acknowledgement message is sent to connect said terminal to said network of said MNO of said visited country.

Abstract: A method for replacing by a HPLMN or a user equipment a set of URSP rules used by the user equipment communicating with a MNO network, the set of URSP rules being called current set of URSP rules, by another set of URSP rules, called new set of URSP rules, the user equipment cooperating with a secure element, the method including storing in the secure element a plurality of URSP rules; when the home network or the user equipment decides to switch from the current set of rules to the new set of rules, sending to the secure element a switching command comprising a list of selection criteria of the new set of URSP rules; replacing in the secure element the current set of URSP rules by the new set of URSP rules, and sending a refresh command.

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.
