Abstract
(EN)
A handover management method according to an embodiment is performed by a session management function (SMF) device, and comprises the steps of: receiving handover information associated with a terminal receiving a predetermined service by accessing a source base station; after the handover information is received, acquiring resource information about a resource used by the source base station when a high reliability-low delay service is provided to the terminal; and requesting a user plane function (UPF) device so that a resource corresponding to the acquired resource information is secured in a target base station.
(FR)
Un procédé de gestion de transfert intercellulaire selon un mode de réalisation de l'invention est effectué par un dispositif de fonction de gestion de session (SMF), et comprend les étapes suivantes : recevoir des informations de transfert intercellulaire associées à un terminal recevant un service prédéterminé en accédant à une station de base source; après la réception des informations de transfert intercellulaire, acquérir des informations de ressource concernant une ressource utilisée par la station de base source lorsqu'un service à fiabilité élevée et faible retard est fourni au terminal; et demander un dispositif de fonction de plan d'utilisateur (UPF) pour qu'une ressource correspondant aux informations de ressource acquises soit assurée dans une station de base cible.
