Abstract
(EN)
The invention relates to a method for establishing a direct radio communication between two or more user devices in a cellular mobile communication system, whereby said users are subscribed to the same operator. According to the invention, a cognitive radio technique is used to detect spectrum resources available for radio communications in a predetermined area containing said at least two user devices. The method is characterised in that it also includes the following steps in which: at least one resource is selected from the available resources, said resource being a resource of the operator common to the two or more user devices; and a direct radio link is established between said two users using the detected free resource of the operator. The invention also relates to a system for establishing a direct radio communication between two or more user devices in a cellular mobile communication system.

La invención se refiere a un procedimiento para establecer una comunicación radio directa entre dos o más dispositivos de usuario dentro de un sistema celular de comunicaciones móviles, estando dichos usuarios suscritos a un mismo operador, que comprende: utilizar una técnica de radio cognitiva para detectar recursos de espectro disponibles para comunicaciones radio en una determinada área dentro de la que se encuentran dichos al menos dos dispositivos de usuario, caracterizado porque el procedimiento además comprende: - seleccionar al menos un recurso de entre los recursos disponibles, siendo dicho recurso un recurso del operador común a dichos dos o más dispositivos de usuario, y establecer un enlace radio directo entre dichos dos usuarios utilizando dicho recurso libre detectado del operador. La invención también se refiere un sistema para establecer una comunicación radio directa entre dos o más dispositivos de usuario dentro de un sistema celular de comunicaciones móviles.

L'invention concerne un procédé permettant d'établir une communication radio directe entre au moins deux dispositifs d'utilisateurs dans un système cellulaire de communications mobiles, les utilisateurs étant abonnés à un même opérateur. Ce procédé consiste : à utiliser une technique de radio cognitive permettant de détecter des ressources de spectre disponibles pour des communications radio dans une zone déterminée dans laquelle se trouvent lesdits dispositifs d'utilisateurs. Ce procédé est caractérisé en ce qu'il consiste en outre : - à sélectionner au moins une ressource parmi celles disponibles, cette ressource étant une ressource de l'opérateur commune auxdits dispositifs d'utilisateurs et à établir un lien radio direct entre lesdits utilisateurs en utilisant la ressource libre détectée de l'opérateur. L'invention concerne également un système permettant d'établir une communication radio directe entre au moins deux dispositifs d'utilisateurs dans un système cellulaire de communications mobiles.
