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 controlling Wireless Local Area Network (WLAN) aggregation and an associated equipment. The method comprises the following steps of: acquiring, by a first radio access network node, WLAN information about a User Equipment (UE); and, controlling, by the first radio access network node, WLAN aggregation for the UE according to the acquired WLAN information. A second radio access network node decides whether to maintain a WT and/or whether to establish WLAN aggregation for the UE when the UE moves to a first radio access network; and, the second radio access network node transmits information about whether to maintain the WT and/or indication information about whether to establish the WLAN aggregation for the UE. The WT receives UE context reference information transmitted by the first radio access network node; and, the WT indexes a UE context according to the received UE context reference information. With the present invention, the WLAN aggregation performance in a UE mobility scenario can be improved.

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 disclosure discloses a system, a data transmission method and a network equipment supporting a Packet Data Convergence Protocol (PDCP) duplication function. The data transmission method supporting a PDCP duplication function comprises the steps of: transmitting, by a first network equipment, a configuration instruction message of a radio bearer supporting a PDCP duplication function to a second network equipment; and, performing, by the first network equipment and the second network equipment, transmission of a data packet of the radio bearer configured with the PDCP duplication function. In the present disclosure, by an interface between the first network equipment and the second network equipment, the transmission of duplicated data packets between the first network equipment and the second network equipment is realized, and the reliability of data transmission is improved. The present disclosure also discloses a method and device for transferring supplementary uplink carrier configuration information and a method and device for performing a connection mobility adjustment.

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.-
