Abstract: front page image
(EN) The present application provides a communication method and a network device, the method comprising: sending data transmission state report instruction information to a DU1 by means of a CU to instruct the DU1 to report data transmission state information between the DU1 and a UE; and sending, to a DU2 by means of the CU, configuration information of the UE and the data transmission state information between the DU1 and the UE reported by the DU1. Therefore, the switching of the UE from the DU1 to the DU2 is implemented, or a bearer of the UE under the DU1 is migrated to the DU2; moreover, the UE is oblivious to the process, so that the continuity of data transmission is improved.
(FR) La présente invention concerne un procédé de communication, et un dispositif de réseau. Le procédé consiste à : envoyer des informations de commande de création de rapport d'état de transmission de données à une DU1, au moyen d'une CU, pour commander à la DU1 de rapporter des informations d'état de transmission de données entre la DU1 et un UE ; et envoyer, à une DU2, au moyen de la CU, des informations de configuration de l'UE, et des informations d'état de transmission de données entre la DU1 et l'UE rapportées par la DU1. L’invention implémente la commutation de l'UE, de la DU1 à la DU2, ou la migration d’une porteuse de l'UE, de la DU1 à la DU2, de façon transparente, améliorant ainsi la continuité de la transmission de données.
(ZH) 本申请提供一种通信方法和网络设备,通过CU向DU1发送数据传输状态上报指示信息,指示DU1上报与UE之间的数据传输状态信息。CU向DU2发送UE的配置信息以及DU1上报的与UE之间的数据传输状态信息。从而,实现UE从DU1切换到DU2,或者,将UE在DU1下的承载迁移到DU2,而在此过程中UE无感知,提高数据传输的连续性。
