摘要： The present invention 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 invention 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 it is ensured that the destination MPTCP agent can continue to perform a management and control operation.

摘要： Embodiments of this application disclose a PSK updating method. A first communication apparatus stores a first PSK for processing, within an aging periodicity of the first PSK, a packet exchanged between the first communication apparatus and a second communication apparatus. The first communication apparatus may receive, within the aging periodicity of the first PSK, a first protocol packet that is sent by the second communication apparatus and includes a first PSK key material for generating a second PSK. The second PSK is for processing, within an aging periodicity of the second PSK, a packet exchanged between the first communication apparatus and the second communication apparatus. It can be learned that the first communication apparatus may update a PSK based on the first PSK key material. Therefore, the PSK stored in the first communication apparatus may change. This reduces a possibility of cracking the PSK in the first communication apparatus, and accordingly avoids security risks.

摘要： Embodiments of the present invention relate to the field of communications technologies, and disclose a data transmission method and a device, to reduce a quantity of TCP-layer ACK packets transmitted on a radio air interface link between a first device and a second device, thereby reducing consumption of radio air interface link resources and improving transmission efficiency of radio service data. A specific solution is as follows: obtaining, by a first device, a TCP-layer ACK; and intercepting the TCP-layer ACK if a TCP-layer data packet corresponding to the TCP-layer ACK is a TCP-layer data packet that is obtained by the first device after the first device parses a link layer data packet received through a radio air interface link by the first device, and the TCP-layer ACK satisfies a preset condition. The present invention is applied to a data packet transmission process based on a TCP connection.

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.
