APPARATUS AND METHOD FOR CONTROLLING E2 NODE IN WIRELESS COMMUNICATION SYSTEM

The 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). A method performed by a near-real time (RT) radio access network (RAN) intelligent controller (RIC) is provided. The method includes 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 includes a control header and a control message, wherein the control header includes a user equipment (UE) identifier (ID), wherein the control message includes parameters regarding a specific control service, and wherein the specific control service is indicated by an RIC control service style corresponding to a category and an index of the specific control service.
