DEVICE AND METHOD FOR SUPPORTING OPERATOR-SPECIFIC SERVICE IN WIRELESS ACCESS NETWORK

Disclosed is a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a post-4th generation (4G) communication system such as long term evolution (LTE). A method by which an apparatus configured to use an interface between a radio access network intelligent controller (RIC) and a node including a base station operates in a radio access network, comprises: generating first information associated with an RIC service; generating second information indicating a type of message to be used for transmitting the first information; and transmitting a message including the first information and the second information.
