5G network slicing is the key to the digital transformation for the 5G network supporting industry. By cutting multiple virtual network slicing on a unified physical network, it can be used to adapt the differentiated requirements of various industrial services such as industrial control, automatic driving, smart grid, telemedicine and so on. 5G network slicing also puts forward new requirements for network management. 5G network slicing management requires user-centric, real-time and on-demand provision of service-guaranteed network slice services. ZTE’s 5G slice management solution meets user-oriented slice requirements, adhering to the core concept of "agile, automatic, intelligent, and open". With the help of the advanced micro-service architecture and template-based service design engine, the fast slice onboarding is achieved. With the help of end-to-end automatic orchestration, deployment and activation functions, the rapid slice fulfillment is realized. With the help of the intelligent closed-loop assurance functions based on big data and AI, automatic operation and maintenance of slices is implemented. With the help of the 5G slice capability exposure platform, it promotes the cross-border integration of 5G and vertical industries, stimulates massive application innovations, and achieves the perfect combination of 5G social values and business values, to create a new digital economy ecosystem. The 5g network slicing management solution will push the technology maturity of 5G commercial system to a new level, and lay a solid foundation for the 5G slice-based network operation model.
