  • Patent number: 9801108
    Abstract: Embodiments of the present application provide a method for a handover without a default bearer. A first network device sends a relocation request to a second network device. The second network device establishes a connection to a third network device indicated by the relocation request, and sends a response to the first network device and indicates that data is to be sent by using a signaling plane. Then the first network device instructs a source network device to forward the data to a target network device according to a forwarding mode indicated by a handover command. Alternatively, after the second network device establishes the connection to the third network device indicated by the relocation request, the third network device caches data, and after a handover of user equipment is completed, the third network device sends the cached data to the second network device.

  • Publication number: 20170195933
    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.
