Abstract: Embodiments of the present invention provide a method for handover between secondary base stations, a network device, and user equipment. The network device instructs each of at least one candidate secondary base station to make a prior path handover preparation, so that each of the at least one candidate secondary base station waits to be selected by user equipment as a target secondary base station. The path handover preparation includes at least one of the following: preconfiguring an access resource for the user equipment or establishing a data transmission channel with the network device. The user equipment is handed over to the target secondary base station in the at least one candidate secondary base station according to configuration information of each of the at least one candidate secondary base station when the user equipment needs path handover.

Abstract: A data transmission method, a data receiving device, and a data sending device are disclosed. An RLC protocol entity unit of a data receive end receives a TCP acknowledgement from a TCP protocol entity unit of the data receive end; and the RLC protocol entity unit sends indication information to an RLC protocol entity unit of a data transmit end, where the indication information is used to indicate whether the RLC protocol entity unit needs to generate a TCP acknowledgement. The RLC protocol entity unit receives the indication information from the RLC protocol entity unit, and sends the TCP acknowledgement to a TCP protocol entity unit of the data transmit end based on the indication information, to ensure that the TCP protocol entity unit ultimately receives only one TCP ACK for one TCP data packet.

Abstract: This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.
