METHOD FOR MANAGING TRANSMISSIONS OF MULTIMEDIA DATA VIA AN INTERNET-TYPE NETWORK IN PARTICULAR TELEPHONE OR VIDEOPHONE DATA, AND SMART CARD FOR IMPLEMENTING THE METHOD

摘要

The invention relates to a method for managing data transmissions via an internet network (RI) between calling (Aa) and called (Ab) subscribers. A ca rd (2a) cooperates with a terminal (1a) and has client/webserver (S WEB), CGI a nd proxy (27a) functions. The proxy function is used for the signaling channels (CS) and data channels (CD). The terminal (1a) and the card (2a) include specific communication protocol layers that make it possible to establish sessions for bidirectional transmission between them and/or with the interne t network (RI). The smart card (2a) stores applications associated with protocols for listing (900a) and for locating subscribers (901a), as well as subscriber profiles (903a). It plays the role of a proxy in the signaling channel (CS) and/or data channel (CD). The invention also relates to the associated card.
