Abstract
(EN) This terminal device, for communicating with one or multiple base station devices, is provided with: a receiving unit which receives from the base station device an RRC reset message that includes DRB settings, the DRB settings including a DRB identifier and an EPS bearer identifier; and a processing unit which, if the DRB identifier is not part of the present settings of the terminal device, EN-DC is configured in the terminal device, and a DRB was configured for the EPS bearer identifier prior to receiving the RRC reset message, associates an established DRB and the aforementioned EPS identifier.
(FR) L'invention concerne un dispositif terminal, permettant de communiquer avec un ou plusieurs dispositifs de station de base, qui comprend : une unité de réception qui reçoit en provenance du dispositif de station de base un message de réinitialisation RRC comprenant des réglages DRB, les réglages DRB comprenant un identifiant DRB et un identifiant de support d'EPS ; et une unité de traitement qui, si l'identifiant DRB ne fait pas partie des réglages actuels du dispositif terminal, EN-DC est configuré dans le dispositif terminal, et un DRB a été configuré pour l'identifiant de porteuse EPS avant la réception du message de réinitialisation RRC, associe un DRB établi et l'identifiant EPS mentionné ci-dessus.
(JA) 一又は複数の基地局装置と通信する端末装置であって、前記基地局装置から、DRB設定を含むRRC再設定メッセージを受信し、前記DRB設定はDRB識別子及びEPSベアラ識別子を含む受信部と、前記DRB識別子が前記端末装置の現在の設定の一部ではなく、前記端末装置にEN-DCが設定されており、前記RRC再設定メッセージを受信する前に前記EPSベアラ識別子に対しDRBが設定されていた場合に、確立したDRBと前記EPS識別子とを対応付ける処理部と、を備える。
