Abstract: The present application discloses a method and eNB equipment for supporting seamless handover. The method comprises the following steps of: receiving, by a target eNB, random access information or an RRC connection reconfiguration completion message from a UE; transmitting, by the target eNB, a data transmission stopping indication message to a source eNB; and, stopping, by the source eNB, transmitting downlink data to the UE, and/or stopping, by the source eNB, receiving uplink data from the UE. The present invention further provides several other methods and eNB equipments for supporting seamless handover. By the methods for supporting seamless handover provided by the present invention, the delay of data transmission and the unnecessary data transmission or unnecessary data monitoring of a source eNB can be avoided, the waste of resources and the power consumption can be reduced, and the missing and duplication transmission of data can be avoided.

Abstract: Methods and apparatuses are provided through which a first node transmits, to a second node, a first message include a radio resource control (RRC) message associated with a terminal and an identifier allocated to the terminal to identify the terminal over an interface. The first node receives, from the second node, a second message including an identifier allocated to the terminal, an identifier of a data radio bearer, and uplink tunnel information. The first node transmits, to the second node, a third message including downlink tunnel information. The first node includes a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical (PHY) layer. The second node includes an RRC layer and a packet data convergence protocol (PDCP) layer.
