Abstract: The present disclosure relates to a communication method and system for converging a 4th-Generation (4G) or 5th-Generation (5G) communication system for supporting higher data rates beyond the 4G system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on 5G communication technology and IoT-related technology. A method of a central unit-control plane (CU-CP) included in a secondary node (or secondary gNB (SgNB)) in a wireless communication system supporting evolved universal terrestrial radio access and new radio dual connectivity includes receiving, from a master node (or master eNB (MeNB)), a first message 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 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.
