Abstract
(EN)
Provided are a cell handover method and device. The method comprises: sending a handover request to a target eNB, so that the target eNB uses a current serving small node as a user plane serving node of a UE after the handover and uses the target eNB as a control plane serving node of the UE after the handover; receiving a handover request acknowledgement sent by the target eNB; sending shunting configuration information about the current serving small node to the current serving small node, and sending the RRC reconfiguration information about the UE to the UE, so that the current serving small node and the UE respectively perform a shunting configuration. Thereby avoiding the problems of the increase of resources required for transmission and large time delay due to the fact that the currently serving small node transmits a large amount of data to the target eNB in the process of cell handover.

L'invention concerne un procédé et un dispositif de transfert intercellulaire. Le procédé consiste : à envoyer une demande de transfert à un nœud B évolué (eNB) cible, de telle sorte que l'eNB cible utilise un petit nœud de service actuel en tant qu'un nœud de service de plan utilisateur d'un équipement utilisateur (UE) après le transfert et utilise l'eNB cible en tant que nœud de service de plan de commande de l'UE après le transfert ; à recevoir un accusé de réception de demande de transfert intercellulaire envoyée par l'eNB cible ; à envoyer des informations de configuration de dérivation concernant le petit nœud de service actuel au petit nœud de service actuel, et à envoyer des informations de reconfiguration de commande de ressource radio (RRC) concernant l'UE à l'UE, de sorte que le petit nœud de service actuel et l'UE effectuent, respectivement, une configuration de dérivation. Ce qui permet d'éviter les problèmes de l'augmentation des ressources requises pour la transmission et de retard important du fait que le petit nœud de service actuel transmet une grande quantité de données à l'eNB cible dans le procédé de transfert intercellulaire.

本发明实施例提供一种小区切换方法及设备。该方法包括:向目标eNB发送切换请求,以使目标eNB将当前服务小节点作为UE切换后的用户面服务节点、将所述目标eNB作为所述UE切换后的控制面服务节点;接收所述目标eNB发送的切换请求确认;向所述当前服务小节点发送所述当前服务小节点的分流配置信息,并向所述UE发送所述UE的RRC重配置信息,以使所述当前服务小节点和所述UE分别进行分流配置。从而避免在小区切换过程中当前服务小节点将大量数据转发至目标eNB导致传输所需的传输资源增加、时延较大的问题。
