Abstract

La présente invention concerne un procédé et un système destinés à une commutation aléatoire de conversation entre les deux côtés lors d'un service d'appel, le procédé comprenant : lors d'un procédé de conversation entre un premier terminal d'utilisateur et un deuxième terminal d'utilisateur par l'intermédiaire d'un serveur d'application (AS), lorsque le serveur AS sait que le premier terminal d'utilisateur met en garde la présente conversation et que le serveur AS reçoit un message de demande portant un code de service de commutation aléatoire provenant du premier terminal d'utilisateur, le serveur AS permet au premier terminal d'utilisateur et à un troisième terminal d'utilisateur associés au message de demande d'effectuer une négociation multimédia mutuelle et permet au deuxième terminal d'utilisateur et au troisième terminal d'utilisateur d'effectuer une négociation multimédia mutuelle, de manière à établir une conversation entre le deuxième terminal d'utilisateur et le troisième terminal d'utilisateur ; ensuite, la conversation entre les premier et deuxième terminaux d'utilisateur est interrompue. La présente invention n'a aucun lien avec les terminaux et les terminaux n'ont pas besoin de prendre en charge la capacité d'envoi d'un message « REFER ». De cette manière, divers types de terminaux du présent réseau peuvent être utilisés. Des conversations peuvent être commutées vers un utilisateur associé ou un utilisateur désigné.
