Abstract
(EN) A data transmission method, a network device and a terminal device. The method comprises: a network device determining activation indication information, wherein the activation indication information is used for indicating the starting or stopping of a transfer control protocol (TCP) quick confirmation function; the network device sending the activation indication information, and where the activation indication information indicates the starting of the TCP quick confirmation function, maintaining a mapping relationship between a TCP sequence number and a radio link control layer protocol data unit (RLC PDU) sequence number; and the terminal device receiving the activation indication information, and starting or stopping the TCP quick confirmation function according to the activation indication information. Therefore, the method for performing data transmission by means of a TCP quick confirmation solution can be optimized.
(FR) L’invention concerne un procédé de transmission de données, un dispositif de réseau et un dispositif de terminal. Le procédé comprend les étapes suivantes : un dispositif de réseau détermine des informations d'indication d'activation, les informations d'indication d'activation étant utilisées pour indiquer le démarrage ou l'arrêt d'une fonction de confirmation rapide d'un protocole de commande de transfert (TCP) ; le dispositif de réseau envoie les informations d'indication d'activation et, lorsque les informations d'indication d'activation indiquent le démarrage de la fonction de confirmation rapide de TCP, maintient une relation de mappage entre un numéro de séquence de TCP et un numéro de séquence d'une unité de données de protocole de couche de commande de liaison radio (PDU RLC); et le dispositif de terminal reçoit les informations d'indication d'activation, et démarre ou arrête la fonction de confirmation rapide de TCP selon les informations d'indication d'activation. Ainsi, le procédé pour effectuer une transmission de données au moyen d'une solution de confirmation rapide de TCP peut être optimisé.
(ZH) 一种数据传输方法、网络设备及终端设备,网络设备确定激活指示信息,所述激活指示信息用于指示开启或者停止传输控制协议TCP快速确认功能;所述网络设备发送所述激活指示信息,在所述激活指示信息指示开启TCP快速确认功能的情况下,维护TCP序列号和无线链路控制层协议数据单元RLC PDU序列号的映射关系。终端设备接收所述激活指示信息,依据所述激活指示信息,开启或者停止TCP快速确认功能,能够优化采用TCP快速确认方案进行数据传输的方法。
