Abstract

L'invention concerne un procédé de communication sans fil et un dispositif terminal. Dans le procédé selon l'invention : un premier dispositif terminal détermine si un premier identifiant de couche 2 (L2 ID) pour un deuxième dispositif terminal est valide ; si le L2 ID est valide, le premier dispositif terminal utilise le L2 ID pour envoyer un message au deuxième dispositif terminal. L'utilisation de L2 ID permet d'assurer la sécurité de l'établissement d'une connexion. En outre, avant que le premier dispositif terminal établisse une connexion directe avec le deuxième dispositif terminal, le taux de réussite de l'établissement de connexion directe peut être amélioré par détermination de la validité du L2 ID du deuxième dispositif terminal.
