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). According to embodiments, an access and mobility management function (AMF) comprises at least one transceiver; and at least one processor, wherein the at least one processor is configured to receive, a mobility management entity (MME) for an evolved node B (eNB), a message associated with a handover required message for an inter-system handover from an evolved packet system (EPS) to 5G system (5GS) with a secondary gNB (SgNB) used as a target next generation node B (gNB), wherein the SgNB and the target gNB are co-located and the eNB is associated with the SgNB in a dual connectivity; transmit, to the target gNB, a handover request message for the inter-system handover from the EPS to 5GS with the SgNB used as the target gNB; and receive, from the target gNB, an acknowledge of the handover request message. The handover required message includes an SgNB user equipment (UE) X2 application protocol ID (SgNB UE X2AP ID) for identifying a UE over X2 interface in the SgNB. The handover request message includes the SgNB UE X2AP ID, and the SgNB UE X2AP ID is allocated at the SgNB.

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.
