During this state, the UE 1000 may power down for brief intervals of time and thus save power.

  • An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours).

Abstract

La présente invention concerne des systèmes, un appareil, un équipement utilisateur (UE), un nœud évolué B (eNB), des supports lisibles par ordinateur et des procédés destinés à l'automatisation des relations de voisinage dans des systèmes de communication LTE (évolution à long terme), LTE avancés ou similaires. Selon un mode de réalisation, un eNB transmet une première communication de configuration ANR demandant à l'UE de rechercher un ou plusieurs points d'accès (AP) de réseau local sans fil (WLAN) qui partagent un premier réseau mobile terrestre public (PLMN) avec l'UE. L'UE reçoit des détails de terminaison WLAN (WT) associés au premier AP, puis génère une entrée de table de relations ANR en associant le premier AP au WT. Ceci peut alors être utilisé pour établir une connexion Xw avec le WT et peut également être utilisé pour l'agrégation LTE/WLAN (LWA) dans certains modes de réalisation.
