O-RAN Certification/Badging Process and End-to-End Test Case Analysis

O-RAN 공인시험 프로세스와 종단간 시험 기술 분석

The O-RAN Alliance is responsible for defining the technical and testing specifications of open radio access networks, aiming for openness, virtualization, and intelligence in these networks. Recently, the application of Korea Open Testing and Integration Center (OTIC) to this alliance has been approved, enabling the issuance of O-RAN certificates and badges. An OTIC plays a crucial role as a testing facility in performing conformance verification and interoperability tests for O-RAN functions and interfaces. In addition, it enables end-to-end system verification adhering to O-RAN principles and processes. These activities can substantially contribute to enhancing the competitiveness of domestic O-RAN products and activating the corresponding ecosystem. We comprehensively describe the O-RAN certification and badging processes. Additionally, we analyze end-to-end test cases that are essential for the proper deployment and operation of 5G systems including O-RANs.
