  Abstract

Open Radio Access Network (Open RAN) technology, which aims to effectively deploy next-generation mobile communication networks and operate them in a data-driven manner, is in the spotlight. Simultaneously, the open source approach, which has achieved great success in the enterprise server domain, is extending into the mobile communication field and making a significant impact on the ecosystem of open RAN. In this paper, we introduce the hardware and software technologies and RAN intelligent controller (RIC) required to implement an open RAN testbed and provide an analysis of the testbed implementation process using open sources. We have made efforts to explain network technology, virtualization and microservices in a way that is accessible to existing mobile communication researchers who primarily focus on wireless technology. Additionally, we thoroughly explore a detailed analysis of messages within the open interfaces during testbed operation, and provide execution result of xApp, aiming to enhance understanding of O-RAN standards and use cases.
