摘要： Embodiments of the present invention provide a data transmission control node, a system, and a data transmission management method. A TCP subflow on which data offloading needs to be performed is selected according to a requirement for running the system. By changing an input item of an MPTCP congestion control algorithm, data on the selected TCP subflow can be migrated to another expected TCP subflow that belongs to a same MPTCP connection as the selected TCP subflow. By taking an additional measure to manage and control MPTCP data transmission on an access network side, a result of the data offloading on the TCP subflow can satisfy the expected requirement for running the system, so as to optimize system performance, and improve practicability of the MPTCP congestion control algorithm.

摘要： The present disclosure provides a method and an apparatus for managing mobility of an MPTCP connection. The method includes: receiving a message that is sent by the source MPTCP agent and that carries an MPTCP context of UE; and saving the MPTCP context, and performing an MPTCP data transmission operation or an MPTCP management and control operation for the UE according to the saved MPTCP context. Embodiments of the present disclosure implement that, in a scenario in which both a source MPTCP agent and a destination MPTCP agent are deployed at a RAN side, when UE moves from a radio access device on which the source MPTCP agent is deployed to a radio access device on which the destination MPTCP agent is deployed, an MPTCP connection is maintained or the destination MPTCP agent can continue to perform a management and control operation.
