Provided is a mobile communication system capable of determining a communication path to implement fast communication by multihop connection. A mobile communication system (1) comprises a mobile station (10), at least one relay station (30), and a base station (20) and implements packet transmission from the mobile station (10) to the base station (20) through a communication path with an intermediary of at least one relay station (30) or through a communication path without an intermediary of a relay station. The mobile communication system (1) is provided with a communication path determiner for determining a communication path with a largest communication speed or a communication path satisfying a required line quality, based on interference levels of respective signals received at a relay station (30) constituting a communication path between the transmitting station and the receiving station, and at the base station (20).
La présente invention concerne un système de communication mobile capable de décider d'un chemin de communication qui peut réaliser une communication haute vitesse à sauts. L'invention concerne plus particulièrement un système de communication mobile (1), qui comprend une station mobile (10), une ou plusieurs stations relais (30) et une station de base, et qui exécute une émission de paquets depuis la station mobile (10) vers la station de base (20) via une ou plusieurs stations relais (30) ou via aucune station relais. Le système de communication mobile (1) comporte un module de décision de chemin de communication chargé de décider, sur la base des niveaux d'interférences des signaux reçus par la station de base (20) et par les stations relais (30) constituant les chemins de communication entre les stations d'émission et de réception, d'un chemin de communication qui fasse preuve de la vitesse de communication la plus élevée, ou d'un chemin de communication qui satisfasse à une qualité de ligne requise.
