The road to development and prosperity of 5G--how to cope with the new challenges of technology, security and ideology

With the promotion and implementation of China's "goal of completing 5G commercialization by 2020", the three major Chinese Telecom operators have defined the 5G commercial deployment and formally identified the first 19 5G network coverage cities. From the point of international respect, the United States, Europe, Japan and Korea are also actively promoting 5G network construction and commercial use. In-depth interaction between 5G technology and vertical field will not only drive the whole society to change imperceptibly, but also make high-speed connection between people and things, people and people, things and things through 5G network in the context of all things connected by 5G+Internet of Things. This also increases the probability of being attacked by hackers and malicious code, and has a fatal impact on mobile office security, sensitive data, and even national infrastructure. At the same time, while facing the upgrading of traditional risks such as technical vulnerabilities and network attacks, 5G also faces some derivative unknown risks, which are more harmful or uncontrollable. The technological characteristics of 5G determine the globalization of risk. Although the global digital divide still exists, the rapid development of network technology in the past decade has narrowed the gap in the field of network in most countries. However, in the face of the major risks of 5G, the experience of countries is basically at the same level, so the international collaborative governance will enter a new stage. Countries around the world should continue to uphold the concept of mutually beneficial symbiosis, seek global cooperation, explore the internationalized application of the three-layer governance framework for promoting the healthy development of 5G globalization. Over the years, we have been focusing on the research on the topic of "network governance system", and have formed a series of influential research reports and network governance models at the national strategic level.
