Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention provides a method for supporting handover, comprising the steps of: informing, by a source base station, a core network whether a direct data forwarding path is available; deciding, by the core network, whether to use direct data forwarding or indirect data forwarding; informing, by the core network, a target base station of information about the direct data forwarding or indirect data forwarding; allocating, by the target base station, data forwarding tunnel information, the target base station allocating the data forwarding tunnel information according to the received information about the direct data forwarding or indirect data forwarding; transmitting, by the target base station, the allocated data forwarding tunnel information to the core network; and informing, by the core network, the source base station of the data forwarding tunnel information. With the present invention, different data forwarding methods are supported to prevent data loss and ensure service continuity.

Abstract: An embodiment of the present disclosure may provide an inter-MeNB handover method in a small cell system, including: making, by a source MeNB and/or target MeNB, a determination as to whether to maintain a SeNB when handover is performed; and triggering different handover processes according to a result of the determination as to whether to maintain the SeNB. Another embodiment of the present disclosure may further provide an inter-MeNB handover device in a small cell system. With the inter-MeNB handover method and device in a small cell system provided by the present disclosure, unnecessary deletion and re-establishment of the bearers at the SeNB for the UE may be reduced. False bearer deletion may be avoided and data forwarding may be reduced. Furthermore, the SeNB may be maintained according to network deployment and SGW re-selection may be supported. Therefore, system capacity and transmission speed of the data may be improved.

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.
