Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif de création de tranche de réseau. Le procédé de création d'une tranche de réseau comprend les étapes suivantes : un terminal transmet à un élément de réseau de communication un message de demande de création de tranche de réseau comprenant des informations d'identification du terminal et des informations de demande de tranche de réseau; le terminal reçoit un message de réponse de création de tranche de réseau transmis selon le message de demande de création de tranche de réseau et à partir de l'élément de réseau de communication, le message de réponse de création de tranche de réseau comprenant des informations d'identification de tranche de réseau. Les modes de réalisation de l'invention peuvent mettre en œuvre une création de tranche de réseau souple et dynamique sur la base d'une exigence de transmission de données de terminal, augmentant ainsi efficacement un taux d'utilisation de ressources de réseau.
