Abstract: A method for handover of User Entity (UE) by a source Base Station (BS) is provided. The method includes determining whether to handover the UE using an X2 interface, transmitting a handover request message to a target BS, the handover request message including Closed Subscriber Group (CSG) information of the target BS, and receiving a handover request acknowledgement message from the target BS, wherein the determining of whether to handover the UE using the X2 interface includes, if there is the X2 interface between the source BS and the target BS, and if the target BS does not support a CSG or the target BS supports a same CSG supported by the source BS, determining to perform the handover of the UE using the X2 interface, and obtaining the CSG information of the target BS through an X2 interface set up procedure.

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.

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: The 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 disclosure provides a method and apparatus for configuring a relay node. A first node transmits to a second node a message that carries information on a radio bearer for a user accessing the second node. Configuration of the radio bearer for data transmission in a multi-hop network is realized through the above method and apparatus.

Abstract: Embodiments of the present invention provide a dual-connectivity (DC) establishment method and device. The first DC architecture includes a Master Node (MN) and a Secondary Node (SN), wherein the SN includes a Central Unit (CU) and a Distributed Unit (DU); and, the CU includes a Control Plane functional entity (CP) and a User Plane functional entity (UP). The method includes steps of: receiving, by an SN-CP, a first SN setup request message transmitted by an MN; transmitting a first resource setup request message to an SN-UP according to the first SN setup request message, and receiving a first resource setup response message transmitted by the SN-UP; and, transmitting, by the SN-CP, a first bearer setup request message to an SN-DU, and receiving a first bearer setup response message transmitted by the SN-DU.

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.
