ZTE 5G Common Core user plane includes UPF function of NGC. ZTE 5G Common Core product are based on full virtualized Cloud Native platform. ZTE 5G Common Core product supports service based 5GC interfaces and supports cross-DC deployment based on slice requirements. ● Micro-service Architecture The application is designed with the concept of "high cohesion and low coupling" and is divided into a series of small services. Each service concentrates on a single service function, running in a separate process. These services, with a clear boundary between each other, use a lightweight communication mechanism (Such as HTTP / REST) to communicate and collaborate with each other to achieve a complete application, so as to meet the needs of services and users. ● Self-service Based on the micro-service architecture, it is highly automated from blueprint design, resource scheduling, lifecycle management, to application status monitoring, control policy updates and other links, and the effective connections of the various links achieve a closed-loop feedback mechanism, so that it realizes one-key deployment installation, comprehensive automated and efficient management. ● Lightweight Virtualization Compared with the virtual machine (VM), container technology is advanced in fast scale-in/out, lightweight, high performance and other aspects, which is developing rapidly and widely used in the IT industry. Cloud Native applications and the underlying virtualization technology achieve decoupling and can be deployed in the container technology to promote resource utilization rate and achieve rapid delivery and agile maintenance of services. ● Stateless 5G core network adopts stateless hierarchical design. The user’s access and session information are stored in the data sharing layer, and various micro-service instances at different locations obtain the user's latest state through the data sharing layer. The stateless application design achieves the separation of applications and data, realizing rapid network elasticity, fault recovery and so on. The user plane function of ZTE Common Core product is optimized with multiple type of technical. It promotes the performance on same hardware resources, and is useful to bring more investment efficiency for operator. ● Optimization base on VM and container to fulfill resources requirement of 5G core network deployment. ● Performance promotion based on open source virtualized switch, the architecture and interface are with openness. ● User plane performance promotion via multiple methods to fulfill performance requirement of carrier level.
