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.

In one example method, an application identity of a source application instance is received by a second mobile edge platform from a first mobile edge platform. The first mobile edge platform provides a service for the source application instance. The source application instance provides a service for a user equipment. A target application instance of the user equipment is determined based on the application identity. The application identity of the source application instance is the same as an application identity of the target application instance. The second mobile edge platform provides a service for the target application instance. A switching notification message is sent by the second mobile edge platform to the target application instance. The switching notification message is used to instruct the target application instance to provide a service for the user equipment.

According to one example method in this application, a serving gateway receives indication information sent by a mobility management entity, and allocates an identifier to a bearer according to the indication information, so as to set up an S1 interface user plane bearer. Data can be switched from the control plane solution to the user plane solution through setup of the user plane bearer.

Method and an apparatus for determining a bearer for mobile edge computing are disclosed. A Mobile Edge Computing (MEC) can obtain a data packet that includes an end marker. The MEC can obtain a bearer identifier and an identifier of UE in a handover procedure according to the data packet that includes the end maker, and requests information about the second bearer from a node of a second bearer. The request can include the bearer identifier of the UE and the identifier of the UE. The node of the second bearer can return a response message and information regarding the second bearer according to the request. The MEC can receive the response message and store the information regarding the second bearer according to the identifier of the UE and the bearer identifier of the UE.

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.
