Abstract: The embodiments of the present disclosure propose a method performed at a first node for transmitting data, comprising: receiving downlink data to be transmitted to a User Equipment (UE) in a non-connected state; and determining whether to buffer the downlink data. The method further comprises: when it is determined that the downlink data is to be buffered, if the first node is a first type of node, determining that a paging procedure is not to be initiated for the UE in the non-connected state, or if the first node is a second type of node, notifying the second node that the downlink data has been buffered, so that the second node determines that the paging procedure is not to be initiated for the UE in the non-connected state. There are further provided a method performed at a second node and corresponding devices and storage media.

Abstract: A method for supporting fast recovery of a User Equipment (UE) includes performing, by a serving base station, UE context synchronization for one or more other base stations in a related small cell cluster when a UE accesses the serving base station, performing, by a base station that the UE performs a radio resource control (RRC) connection re-establishment, the RRC connection re-establishment for the UE according to UE context saved in a synchronization process. The present also discloses another method and system for supporting UE fast recovery. By applying the technical solution disclosed by the present disclosure, when the UE moves in a small cell scenario, the UE can be recovered quickly in the case of a failure, so as to avoid the UE returns to an idle mode, avoid data loss, guarantee business continuity, and improve UE experience.

Abstract: The present application discloses handover methods and apparatuses. One specific embodiment of the handover method comprises receiving a handover request message from a source base station by a target base station; determining whether to add a secondary base station for setting up a dual-connectivity for a user equipment (UE) according to the handover request message; and performing a handover operation and a dual-connectivity setup operation in response to the determination of adding the secondary base station. The dual-connectivity can be set up for the UE during the handover in the embodiments.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.The present invention provides a method of a base station for supporting an inter-system handover from an evolved packet system (EPS) system to a 5th generation (5G) system. The method comprises receiving, from an access and mobility management function (AMF), a handover request message including E-UTRAN radio access bearer (E-RAB) information and quality of service (Qos) flow information, identifying whether a protocol data unit (PDU) session is accepted or not, determining whether a data forwarding for at least one Qos flow associated with the PDU session is accepted or not based on the E-RAB information and the Qos flow information in case that the PDU session is accepted and transmitting, to the AMF, a handover request acknowledgement message including information on the at least one Qos flow based on the determination. The method solves the data forwarding problem during the movement of a UE between an LTE system and a 5G system, so that the loss of data is avoided and the continuity of services is ensured.
