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.
