초록

Radio access networks (RANs), referring to networks that connect user equipment (UE) to a core network (CN), are core concepts in mobile communications. With the rapid increase in network traffic, the demand for next-generation wireless communication technologies to accommodate this growth has been rising. There is a growing need to optimize network resources and enhance efficiency, reliability, and processing performance through virtualization, cloud-based services, and intelligent technologies. In response to these demands, the O-RAN Alliance was established in 2018, and research on next-generation networks has been actively conducted. However, only a limited number of studies on O-RAN have been identified in Korea. In this study, we extracted keywords from research literature related to RANs from the Web of Science (WoS) for network analysis and reviewed research cases on the RAN Intelligent Controller (RIC), which is an intelligent component of O-RAN.
