    摘要: The present disclosure relates to a communication method and system for converging a 4th-Generation (4G) communication system or a 5th-Generation (5G) communication system for supporting higher data rates beyond the 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. A method of a central unit-control plane (CU-CP) included in a secondary node (SN) (or secondary gNB (SgNB)) in a wireless communication system supporting evolved universal terrestrial radio access and new radio dual connectivity (EN-DC) includes receiving, from a master node (MN) (or master eNB (MeNB)), a first message for requesting the SgNB to allocate a radio resource for a bearer, and transmitting a second message, including indication information indicating whether a packet data convergence protocol (PDCP) version of the bearer has been changed, to the CU-UP included in the SgNB. The indication information is generated based on the first message.

    摘要: This disclosure relates to a method of a terminal in a wireless communication system, the method comprising: communicating with a gateway based on a first packet data network, PDN, connection, related to a first communication system; establishing a bearer with the gateway on a second communication system while the terminal is in a radio resource control, RRC, connection state on the first communication system; establishing a second PDN connection related to the second communication system; performing switching from the first communication system to the second communication system; transmitting a link start marker packet to the gateway based on the second PDN connection; and transmitting and receiving data using the gateway based on the second PDN connection.
