Abstract:
A method for managing transmissions of multimedia data via an internet-type network between a first subscriber system and a second subscriber system including:at least one phase of signaling data exchange, via a signaling channel, using a predetermined signaling protocol, and a phase of exchanging said multimedia data via a data channel using a predetermined communication protocol; wherein at least said first subscriber system includes a first terminal provided with a web-type navigator and a first smart card reader that cooperate via a first smart card, said first smart card including an instance of a first software layer forming a specific communication protocol layer, and said first terminal including an instance of a second software layer forming a specific communication protocol layer and forming an interface with at least said web-type navigator; said first and second types of software layers each further including at least a first autonomous software entity of a client-type and a second autonomous software entity of a server-type, said entities cooperating in such a way as to enable an establishment of bi-directional data exchange sessions between said first terminal and said first smart card; wherein said first smart card offers the function of a client/web server for enabling an establishment of a bi-directional data exchange between said first terminal of said first subscriber system and said second subscriber system via said internet-type network; and wherein said first smart card further includes: a filter comprising application software of predetermined functional characteristics which receives and/or sends protocol data units to and/or from said first and second autonomous software entities of said first software layer, said filter being under the control of said second autonomous software entity of said first software layer and cooperates with said first and second autonomous software entities of said first software layer to open a session with said first and second autonomous software entities of said second software layer in order to form a first proxy function and to control predetermined characteristics of data exchanges that pass between said first subscriber system and said second subscriber system via at least one of said signaling channels and/or data channels during said phases of exchanging signaling data and/or multimedia data.
