Abstract

La présente invention concerne un procédé de transmission, un dispositif et un système de communication pour données de service. Le procédé de transmission des données de service comporte les étapes consistant à : déterminer un mode de transmission de données pour le service en fonction du type de service demandé par un utilisateur en périphérie de cellule; communiquer le mode de transmission de données déterminé pour le service à l'utilisateur en périphérie de cellule et mettre en œuvre la transmission des données du service avec l'utilisateur en périphérie de cellule en fonction du mode de transmission de données déterminé pour le service. Les modes de réalisation de la présente invention permettent d'améliorer la souplesse de la transmission de données de service pour l'utilisateur en périphérie de cellule, garantissant ainsi avantageusement la qualité de service demandée par l'utilisateur en périphérie de cellule.
