MANAGEMENT OF SUBSCRIBER PROFILES SIMULTANEOUSLY ACTIVE IN AN EUICC CARD USING A PLURALITY OF SEPARATE LINKS
First Claim
1. A secure element (300) suitable for interacting with a host terminal (200), the secure element comprising a communication interface controller (305) for communicating with the host terminal and comprising a plurality of subscriber profiles (P), each subscriber profile authenticating a user in a mobile telephony network (100, 100′
- ), and being configured to simultaneously activate a plurality of subscriber profiles, wherein the communication interface controller is configured to respectively associate a plurality of separate communication links (100, 410-1, 410-3, 410-4, 420-1, 420-3, 420-4) with the host terminal with the plurality of active subscriber profiles.

Abstract
Disclosed is management of a plurality of active subscriber profiles at the same time within the same secure element integrated in a host terminal. A baseband processor of the terminal and a communication interface controller of the secure element together establish different separate links for each one of the active profiles. It is thus possible to address, and therefore to simultaneously use, a plurality of profiles. A link can be the conventional ISO 7816 link. The HCI/SWP interface allows a large number of logical links (or HCI pipes) to be established using a single additional tab for connecting the secure element in the terminal. Each active profile is thus associated with an HCI pipe for routing messages relating thereto. As a variant or in combination, an SPI interface allows master-slave logical links to be established.

14. A method for controlling communication between a host terminal (200) and a secure element (300) integrated in the host terminal and comprising a plurality of subscriber profiles (P), each authenticating a user in a mobile telephony network (100, 100′
- ), the method comprising;
establishing (44), for each active subscriber profile (P) of a plurality of subscriber profiles simultaneously active in the secure element, a separate communication link (100, 410-1, 410-3, 410-4, 420-1, 420-3, 420-4) between the host terminal and the secure element; and routing (50-52, 65-67), in the host terminal or in the secure element, a stream of messages relating to an active subscriber profile to the communication link established for said active subscriber profile. - View Dependent Claims (15)
