Device and method for removing e2 interface-related information in radio access network

Abstract

The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. According to embodiments disclosed herein, provided is a method performed by a near-real time (RT) radio access network (RAN) intelligent controller (RIC). The method may comprise the steps of: receiving an E2 removal request message, for indicating a shutdown of the second node, from an E2 node via an E2 interface, wherein the shutdown of the E2 node is configured from service management and orchestration (SMO); transmitting an E2 removal response message to the E2 node via the E2 interface; and removing the configuration of the E2 node from the Near-RT RIC in response to the E2 removal request message.
