Abstract

La présente invention concerne un procédé de traitement pour un nœud B évolué secondaire (SeNB), lequel procédé comprend les étapes suivantes : une entité de gestion de mobilité (MME) reçoit un premier message de demande en provenance d'un nœud B évolué maître (MeNB), le premier message de demande servant à demander la mise en œuvre d'un traitement de connexion double sur le SeNB ; et la MME envoie un second message de demande au SeNB en fonction du premier message de demande, le second message de demande servant à demander au SeNB la mise en œuvre d'un traitement de connexion double. Cette solution permet de résoudre le problème existant dans l'état de la technique selon lequel une connexion double d'un nœud B évolué ne peut pas être effectuée en cas d'absence d'interface X2, de sorte que l'effet de connexion double du nœud B évolué puisse également être obtenu en cas d'absence d'interface X2.<sb />
