Method of establishing a link between the applications of a subscriber authentication card and an IMS network

摘要

The method involves establishing a secured link between a terminal (10) e.g. mobile telephone, and an internet protocol multimedia subsystem network. Resources of the secured link are shared between the terminal and a subscriber authentication card (11) by a proxy server (14) embarked in the terminal or by an internet protocol cell system that serializes internet protocol packets transmitted and received by the terminal and the card.
