Management of subscriber profiles simultaneously active in an eUICC card using a plurality of separate links
First Claim
1. A secure element configured to interact with a host terminal, the secure element comprising:
- a communication interface controller for communicating with the host terminal and comprising a plurality of subscriber profiles, each subscriber profile authenticating a user in a mobile telephony network, 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 with the host terminal with the plurality of active subscriber profiles,wherein a first communication link of the communication links, associated with a first active subscriber profile among the plurality of active subscriber profiles, is established on a first physical link between the secure element and the host terminal, andwherein a second communication link of the communication links, associated with a second active subscriber profile among the plurality of active subscriber profiles and distinct from the first active subscriber profile, is established on a second physical link between the secure element and the host terminal,the second physical link being distinct from the first physical link.

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.

19. A method for controlling communication between a host terminal and a secure element integrated in the host terminal and having a plurality of subscriber profiles stored therein that each authenticate a user in a mobile telephony network, the method comprising:
-
establishing, for each active subscriber profile of a plurality of subscriber profiles simultaneously active in the secure element, a separate communication link between the host terminal and the secure element, wherein a first communication link of the communication links, associated with a first active subscriber profile among the plurality of active subscriber profiles, is established on a first physical link between the secure element and the host terminal, and wherein a second communication link of the communication links, associated with a second active subscriber profile among the plurality of active subscriber profiles and distinct from the first active subscriber profile, is established on a second physical link between the secure element and the host terminal, the second physical link being distinct from the first physical link; and routing, 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 (20)
