APPARATUS AND METHOD FOR CONTROLLING E2 NODE IN WIRELESS COMMUNICATION SYSTEM

The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than 4th generation (4G) communication systems such as long term evolution (LTE). According to embodiments of the present disclosure, a method performed by a near-real time (RT) radio access network (RAN) intelligent controller (RIC), comprises the steps of: generating an RIC control request message; transmitting the RIC control request message to an E2 node; and receiving, from the E2 node, an RIC control acknowledge message or an RIC control failure message, wherein the RIC control request message comprises a control header and a control message, the control header comprises a user equipment (UE) identifier (ID), the control message comprises one or more parameters regarding a specific control service, and the specific control service may be indicated by an RIC control service style corresponding to a category and an index of the specific control service in the RIC control service style.
