Abstract: The present disclosure relates to mode switching methods, data flow splitting methods, and apparatus. One example mode switching method includes generating, by a first device, first indication information, where a packet data control protocol (PDCP) entity in the first device is connected to at least two radio link control (RLC) entities in a second device, and sending, by the first device, the first indication information to the second device, where the first indication information is used to indicate that transmission between a first RLC entity in the at least two RLC entities and the PDCP entity in the first device is to be canceled. The second device stops the transmission between the first RLC entity and the PDCP entity based on the first indication information.

Abstract: Embodiments of this application provide a duplication mode communication processing method in a central unit-distributed unit (CU-DU) architecture. In a possible implementation, in a process of establishing a user plane tunnel between a CU and a DU by exchanging information about uplink tunnel endpoints and information about downlink tunnel endpoints, the DU provides an identity of a primary path to the CU, thereby implementing a duplication mode of a data radio bearer.

Abstract: A second access network node sends endpoint information of a second transmission path on the second access network node side to the first access network node. The second transmission path is a transmission path that is between the second access network node and a third access network node. The third access network node sends endpoint information of the second transmission path on the third access network node side to the first access network node. The first access network node sends the endpoint information of the second transmission path on the third access network node side to the second access network node, and sends the endpoint information of the second transmission path on the second access network node side to the third access network node.

Abstract: Embodiments of the present invention provide a data transmission method, user equipment, and a base station. The method can include receiving, by user equipment, indication information for stopping transmission sent by a base station, where the indication information for stopping transmission is configured to instruct the user equipment to stop transmitting uplink data for at least one service by through an access point AP of a wireless local area network WLAN. The method can also include stopping, by the user equipment according to the indication information for stopping transmission, transmitting the uplink data for the at least one service through the AP. In this process, the user equipment reduces a data volume of uplink data transmitted through the WLAN, so as to decrease a probability that an uplink data collision occurs in the WLAN, thereby improving service quality.
