Method and device for measuring performance in wireless communication system
The disclosure relates to a 5 th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than 4 th generation (4G) communication systems such as long term evolution (LTE). A method performed by an E2 node is provided. The method includes a step of transmitting a radio access network (RAN) intelligent controller (RIC) indication message to a RIC, wherein the RIC indication message comprises an E2 service model (E2SM)-KPM indication message format 1 and an E2SM-KPM indication message format 2 for key performance measurement (KPM), the E2SM-KPM indication message format 1 does not comprise terminal identification information, and the E2SM-KPM indication message format 2 comprises terminal identification information. According to embodiments of the disclosure, the method performed by the E2 node includes a step of receiving a radio access network (RAN) intelligent controller (RIC) control message from the RIC, wherein the RIC control message can comprise slice identification information and control information with respect to a network slice corresponding to the slice identification information.
