Abstract

La présente invention concerne un terminal de communication fonctionnant comme un point d'accès destiné à un terminal esclave afin d'établir de manière appropriée une connexion de communication entre le terminal esclave et une tranche. Dans un terminal d'utilisateur (100) qui fonctionne comme un point d'accès pour un terminal, et établit une connexion de communication entre le terminal esclave et une tranche qui est un réseau virtualisé généré sur une infrastructure de réseau, des informations de gestion de terminal esclave associant des informations d'identification d'un terminal esclave (110) et des informations d'identification (ID de tranche) d'une tranche servant de destination de connexion de communication sont stockées sur la base d'informations de tranche de connexion. Une unité de commande de communication (101) réalise un traitement de communication entre le terminal esclave (110) et la tranche servant de destination de connexion de communication sur la base des informations de gestion de terminal esclave stockées dans une table de gestion de terminal esclave (102).
