Future beyond fifth-generation (B5G) and sixth-generation (6G) mobile
communications will shift from facilitating interpersonal communications to
supporting Internet of Everything (IoE), where intelligent communications with
full integration of big data and artificial intelligence (AI) will play an
important role in improving network efficiency and providing high-quality
service. As a rapid evolving paradigm, the AI-empowered mobile communications
demand large amounts of data acquired from real network environment for
systematic test and verification. Hence, we build the world's first true-data
testbed for 5G/B5G intelligent network (TTIN), which comprises 5G/B5G on-site
experimental networks, data acquisition & data warehouse, and AI engine &
network optimization. In the TTIN, true network data acquisition, storage,
standardization, and analysis are available, which enable system-level online
verification of B5G/6G-orientated key technologies and support data-driven
network optimization through the closed-loop control mechanism. This paper
elaborates on the system architecture and module design of TTIN. Detailed
technical specifications and some of the established use cases are also
showcased.Comment: 12 pages, 10 figure
