Abstract

La présente invention concerne, selon des modes de réalisation, des procédés et des appareils de distribution de spectre dans une communication D2D. Un procédé mis en œuvre au niveau d'un élément de réseau de gestion de politique dans un système de communication consiste : en réponse à la réception (210) d'une demande de rattachement ou d'une demande de mise à jour d'emplacement à partir d'un dispositif terminal transmis par un élément de réseau d'exécution de politique dans le système de communication, à générer, au niveau de l'élément de réseau de gestion de politique, une politique de distribution de spectre dans la communication D2D pour le dispositif terminal ; et à transmettre (220) la politique générée à l'élément de réseau d'exécution de politique destinée à être utilisée dans la distribution de spectre dans la communication D2D pour le dispositif terminal. Ainsi, un mécanisme de distribution de spectre dynamique et flexible basé sur une commande de politique peut être fourni pour une communication D2D, ce qui permet de profiter pleinement d'une ressource de spectre limitée dans des communications D2D en vue d'un bénéfice maximal.
