Abstract

Les modes de réalisation de la présente invention concernent un procédé de commande de communication et son dispositif associé. Le procédé comprend les étapes suivantes : un premier équipement terminal acquiert des premières informations de type d'équipement diffusées par un second équipement terminal, les informations de premier type d'équipement étant utilisées pour indiquer le type d'équipement du second équipement terminal ; et selon les premières informations de type d'équipement, il détermine s'il faut établir une communication directe à courte portée avec le second équipement terminal. La présente invention réalise ainsi une communication directe à courte portée entre des équipements terminaux et réduit la complexité de communication entre les équipements terminaux.
