Abstract

L'invention porte sur un procédé, un équipement et un système pour établir un chemin de communication directe. Le procédé comprend les opérations suivantes : après qu'une station de base dans laquelle un utilisateur appelant réside a reçu un message de requête concernant l'établissement d'une communication directe entre l'utilisateur appelant et un utilisateur appelé, la station de base attribue un identificateur de chemin de plan utilisateur de communication directe à l'utilisateur appelant et à l'utilisateur appelé, et attribue des informations de configuration de ressource d'interface radio à un chemin de communication directe entre l'utilisateur appelant et l'utilisateur appelé ; et la station de base dans laquelle l'utilisateur appelant réside envoie l'identificateur de chemin de plan utilisateur de communication directe et les informations de configuration de ressource d'interface radio attribués à l'utilisateur appelant et à l'utilisateur appelé, et indique à l'utilisateur appelant et à l'utilisateur appelé d'effectuer une configuration de support. Au moyen des modes de réalisation de la présente invention, le chemin de communication directe peut être établi entre deux équipements utilisateurs adjacents, de telle sorte que la transmission de données de plan utilisateur entre les UE adjacents ne nécessite pas la participation d'un réseau d'infrastructure, et un retard de communication et une occupation de ressources réseau sont réduits.
