Abstract

L'invention concerne le domaine des télécommunications, notamment un procédé et un dispositif de transfert de messages sur la base de LTE-LAN qui active une technique d'adressage de couche deux pour réaliser des communications entre un AP et d'autres éléments de réseau dans un système LTE-LAN. Ledit procédé consiste : en ce qu'un AP reçoit un premier message de données provenant d'un premier élément de réseau, obtient les informations d'identification d'un UE et les informations identifiant la couche deux configurée correspondant aux informations d'identification de l'UE, génère un second message de données sur la base du premier message de données, et transmet le second message de données à un second élément de réseau selon les informations d'identification de couche deux, le premier élément de réseau et le second élément de réseau étant un UE et un GW respectivement, un GW et un UE respectivement, ou les deux GW. Le procédé permet ainsi de résoudre le problème de transfert de messages de données de couche deux dans des systèmes LTE-LAN, active les communications entre des UE, des AP, et des GW, et conserve les dépenses d'interface hertzienne. En outre, un AP ne nécessite pas de fonctions de transfert de couche IP, ce qui réduit efficacement les coûts de fabrication de AP, ainsi que le coût de déploiement de réseau de système LTE-LAN, de son fonctionnement et de son entretien.
