Abstract:

As the industrial digital transformation progresses deeper, new scenarios and applications have placed higher demands for industrial network infrastructure, encompassing ubiquitous connectivity, deterministic transmission, integration of control networks and computing resources, open intelligence, and secure controllability. Industrial 5G stand-alone non-public network (SNPN), leveraging its differentiated advantages in asset exclusivity, resource specialization, flexible deployment, autonomous management, and security reliability, are expected to serve as a powerful supplement to traditional industrial networks and operator 5G virtual/hybrid private networks. Based on the core requirements of industrial scenarios, this paper elaborates on the system architecture and functional characteristics of the industrial 5G SNPN for building a new industrial network exclusive digital foundation, clarifying its key capabilities in industrial application support, computing network collaboration, and network security protection. Through the construction of an integrated digital foundation of “connection management-computing & network collaboration-security protection”, the industrial 5G SNPN provides universal connectivity, guaranteed transmission, and autonomous controllability as the underlying support for the new industrial network, facilitating the transition from automation to intelligence and providing strong support for the digital transformation of industries.

Key words: industrial 5G SNPN, new industrial network, industrial internet, network architecture
