Abstract: This application provides a data transmission method and communications devices. In some implementations, a terminal device receives, from a first server, first indication information indicating a sequence number of data that is of an application and that has been received by the first server from the terminal device. After a connection between the terminal device and a second server is established, the terminal device transmits data of the application through the connection between the terminal device and the second server according to the first indication information.

Abstract: A domain name access method and a device are described. As described herein, a domain name server (DNS) server performs resolution on a domain name requested by the terminal device. The DNS server may then send an internet protocol (IP) address of an application server obtained through the resolution and use condition information to the terminal device. With this, communication efficiency of the terminal device can be improved, and waste of transmission resources in a communications system is also avoided.

Abstract: A data forwarding method includes receiving, by a session management function network element, information about a first bearer in a first network from an access and mobility management function network element; and sending flow information of a first flow in a second network and forwarding information to the access and mobility management function network element. The flow information indicates a flow for data forwarding, and the forwarding information is used for forwarding the first flow to a tunnel corresponding to the first bearer.

Abstract: Embodiments of the present disclosure disclose a policy control method for multipath transmission, and a related device. User equipment (UE) supporting multipath transmission performs service packet transmission using at least two transmission subflows. The method includes: receiving, by a policy decision network element, association information of the at least two transmission subflows from a communication peer, where the association information includes flow identifiers of the at least two transmission subflows; determining, by the policy decision network element, a resource modification policy of at least one transmission subflow in the at least two transmission subflows based on the association information; and sending, by the policy decision network element, the resource modification policy to a forwarding plane network element corresponding to the at least one transmission subflow.

Abstract: Embodiments of this application provide an application data migration method, including: obtaining, by a network device, a first, second, and third parameter, where the first parameter includes a delay in communication between a terminal device and a first server through a first connection, the second parameter includes a delay in communication between the terminal device and a second server through a second connection, and the third parameter includes a time for synchronizing a context between the first server and the second server; and if the first parameter is greater than a sum of the second parameter and the third parameter, determining, by the network device, that application data on the terminal device needs to be migrated from the first connection to the second connection; otherwise, determining, by the network device, that application data does not need to be migrated from the first connection to the second connection.
