Title
(EN) ESTABLISHING A DEVICE-TO-DEVICE COMMUNICATION SESSION
(FR) ÉTABLISSEMENT D'UNE SESSION DE COMMUNICATION DE DISPOSITIF À DISPOSITIF
Abstract
(EN)
A method is disclosed for establishing a device-to-device communication session between mobile devices (MD1, MD2) which are mutually connectable via a D2D communication channel (DDC) and individually connectable to a mobile network (MN), comprising: • - preloading (120) an initiation key on each of the mobile devices (MD1, MD2), the initiation key being associated with a validity period; and on each of the mobile devices (MD1, MD2): • - verifying (140) a validity of the initiation key based on a current time; • - if the initiation key is deemed valid, generating (160) a session key using the initiation key by using the initiation key in performing (164, 166) a key agreement procedure between the mobile devices (MD1, MD2) over the D2D communication channel (DDC), the key agreement procedure resulting in the session key if the initiation key used by each of the mobile devices matches; and • - establishing (180) the D2D communication session over the D2D communication channel (DDC) based on the session key.

L'invention concerne un procédé pour établir une session de communication de dispositif à dispositif entre des dispositifs mobiles (MD1, MD2) qui sont mutuellement connectables par l'intermédiaire d'un canal de communication D2D (DDC) et individuellement connectables à un réseau mobile (MN), comprenant : •-le préchargement (120) d'une clé d'initiation sur chacun des dispositifs mobiles (MD1, MD2) , la clé d'initiation étant associée à une période de validité ; et sur chacun des dispositifs mobiles (MD1, MD2) : •-la vérification (140) d'une validité de la clé d'initiation sur la base d'un temps actuel ;-si la clé d'initiation est estimée valide, la génération (160) d'une clé de session au moyen de la clé d'initiation en utilisant cette même clé d'initiation dans l'exécution (164,166) d'une procédure d'approbation de clé entre les dispositifs mobiles (MD1, MD2) sur le canal de communication D2D (DDC), la procédure d'approbation de clé permettant d'obtenir la clé de session si la clé d'initiation clé utilisée par chacun des dispositifs mobiles correspond; et •-l'établissement (180) de la session de communication D2D sur le canal de communication D2D (DDC) sur la base de la clé de session.
