Abstract: A method for sending an end marker, a device, and a system, where the method includes receiving, by a source AN through a source path between the source AN and a core-network user-plane device, a first end marker sent by the core-network user-plane device. The method further includes generating, by the source AN, N second end marker(s) based on the first end marker, where N is the number of source DRB(s) corresponding to the source path, and sending, by the source AN, the N second end marker(s) to a target AN through a forwarding path corresponding to the source path. According to the method, when a DRB is unknown to a core network, a target AN can accurately obtain a DRB-based end marker. This ensures correct sorting of downlink data of UE on a target DRB in a handover scenario.

Abstract: A data migration method and an apparatus are applied to a scenario in which a user plane gateway communicating with a terminal is changed from a source user plane gateway to a target user plane gateway. The target user plane gateway receives an address of the terminal from a control plane gateway, obtains an Ethernet data packet based on the address of the terminal, and sends the Ethernet data packet to an Ethernet interface, so that a switch obtains the Ethernet data packet through the Ethernet interface, and updates a MAC address table based on the Ethernet data packet.

Abstract: A network access method includes a first terminal that sends a first message to an access management network element in a first non-public network, where the first message is used to request to register the first terminal with the first non-public network. The first terminal receives a second message from the access management network element, where the second message is used to indicate that registration of the first terminal with the first non-public network is rejected, the second message includes first indication information, and the first indication information indicates that access of the first terminal to the first non-public network is forbidden. The first terminal adds information about the first non-public network to a forbidden network list of the first terminal based on the first indication information.
