The communication system according to the present invention is made up of: a connected communication terminal (1) to which communication is requested; a connecting communication terminal (3) that requests a communication with the connected communication terminal (1); a session management server (4) that manages sessions between the communication terminals; a trigger server (5) that transmits, to the connected communication server (1), the request made by the session management server (4); and routers (6 and 7) that relay between the connecting communication terminal (3) and the connected communication terminal (1), and a network (2). In the system, the connected communication terminal (1) holds a permission list (L) that is a list of communication terminals to which connection is permitted, and the session management server (4) judges, with reference to the permission list (L), whether or not the communication between the connected communication terminal (1) and the connecting communication terminal (3) is permitted.
Le système de communication selon la présente invention est fait: d'un terminal de communication connecté (1) auquel une communication est demandée; d'un terminal de communication se connectant (3) qui demande une communication avec le terminal de communication connecté (1); d'un serveur de gestion des sessions (4) qui gère les sessions entre les terminaux de communication; d'un serveur de déclenchement (5) qui transmet, au serveur de communication connecté (1), la demande faite par le serveur de gestion des sessions (4); et de routeurs (6 et 7) qui font le relais entre le terminal de communication se connectant (3) et le terminal de communication connecté (1) et d'un réseau (2). Dans le système, le terminal de communication connecté comporte une liste de permissions (L) qui est une liste de terminaux de communication avec lesquels la connexion est permise et le serveur de gestion (4) juge, en se référant à la liste des permissions (L), si la connexion entre le terminal de communication connecté (1) et le terminal de communication se connectant (3) est permise ou non.
