Abstract
Disclosed is a technique for switching from a master node to a secondary node in a communication system. A method of a first communication node may comprise: adding the first communication node as a primary secondary cell (PSCell) to a second communication node through dual connectivity (DC); generating a first user plane path for smart dynamic switching (SDS) and a first instance for supporting the first user plane path according to a request from the second communication node; transmitting information on the first user plane path and the first instance to a terminal; receiving user data based on the first user plane path from the terminal as the first instance; and transmitting the user data to a core network using the first user plane path.
