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: Methods and apparatuses are provided in a wireless communication system. A first message is transmitted, from a master base station, to a secondary base station, for requesting the secondary base station to allocate resources for a dual connectivity (DC) operation. A second message is received from the secondary base station, after transmitting the first message. A third message is transmitted to the secondary base station, after receiving the second message. The first message includes a quality of service (QoS) flow identifier (ID) and available data radio bearer (DRB) IDs. The second message includes the QoS flow ID and a DRB ID corresponding to the QoS flow ID. The third message includes tunnel information for the DRB ID including an Internet protocol (IP) address and a tunnel endpoint identifier (TEID).

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.
