Abstract: Embodiments of the present invention disclose a bearer handover control device and control method. The method includes: receiving, by a network side device, a bearer handover message; and determining, by the network side device according to the bearer handover message, a bearer needing to be handed over in all bearers, so that an end marker End Marker message is sent to a source base station only for the bearer needing to be handed over. By using the foregoing solutions, for a multi-connection scenario, a network side device can determine a bearer needing to be handed over, so that an end marker message is sent only for the bearer needing to be handed over, which can prevent discarding of subsequent data of a bearer that is not to be handed over, and ensure multiple connections between a UE and base stations, thereby improving stability of a system.

Abstract: The present application relates to a data migration method and an apparatus, which 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. Thus, the switch updates the MAC address table in a timely manner, and the switch can send, through a correct port based on an updated MAC address table, downlink data to the terminal, to effectively prevent a loss of the downlink data.

Abstract: The present invention is applicable to the field of communications and provides a session establishment method and apparatus. The method includes: acquiring an infrastructure virtual circuit IVC corresponding to a user equipment UE; sending a virtual local area network VLAN label corresponding to the IVC to a customer location function set, so that the customer location function set adds the VLAN label to a packet of the UE, where the VLAN label is configured by an L2 session control functional entity for the IVC; and notifying an L2 forwarding functional entity of the VLAN label, so that the L2 forwarding functional entity forwards, to the IVC, the packet sent by the customer location function set and added with the VLAN label. In the present invention, a case in which the L2 forwarding functional entity needs to store a large MAC table is avoided, and packet forwarding efficiency is improved.
