  • the PGW when the gateway determines that the UE is in the idle state, the PGW is instructed to deactivate the PDN connection of the UE, so that the UE occurs at the UE location after initiating the attachment to the EPS network separated from the control plane and the user plane.
  • the UE can be reactivated, which effectively avoids the waste of the bearer resources caused by the long distance between the new SGwU and the previously accessed PGwU, and the delay of the delivery of the user packets, thereby improving the user experience of using the service.

Abstract

La présente invention porte sur un procédé, un appareil et un système de commande d'équipement utilisateur, et sur une passerelle de réseau. Le procédé comprend les étapes suivantes : la passerelle de réseau détermine que l'équipement utilisateur, UE, est dans un état de repos ; et la passerelle de réseau ordonne à une passerelle de réseau de données par paquets, PGW, de désactiver la connexion PDN de l'UE.
