Simplified Network

ZTE 5G Common Core User Plane functions include the UPF function in 5GC and the user plane functions of GGSN and SAE-GW in 2G/3G/4G networks. ZTE 5G CommonCore User Plane functions, which are based on a fully virtualized cloud native architecture, support the cross-DC deployment based on slice requirements. • Microservice architecture: The essence of the SBA is based on the three principles: “self-contained, reusable, and independent management”. The network function is designed with the concept of “high cohesion, low coupling” and is divided into a series of small services. Each service focuses on a single business function, running in an independent process, having clear boundaries between services, and using lightweight communication mechanisms to communicate with each other to achieve a complete application to meet the needs of services and users. • Self-service: Based on the Microservice architecture, a high degree of automation is achieved from the blueprint design, resource scheduling and orchestration and lifecycle management, application state monitoring, control strategy update and other aspects for effective linkage between the various links. A closed-loop feedback mechanism can be realized for one-click deployment, full autonomy, and efficient management of services. • Lightweight virtualization: Compared to VMs, container technology has the advantages of rapid scaling-in/out, lightweight, and high performance, and is rapidly and widely used in the IT industry. The cloud native application and the underlying virtualization technology are decoupled, and can be deployed in the container technology to achieve improvement, fast service delivery, and agile maintenance of resource utilization. ZTE 5G Common Core supports both virtual machine-based and container-based deployment ways. • Stateless: The 5G Common Core adopts a stateless layered design so that user access and session information is stored in the data sharing layer and each Microservice instance in different locations can obtain the latest state of the user through the data sharing layer. The stateless application design enables separation of applications and data, achieving rapid network resiliency and failure recovery. ZTE 5G Common Core user plane performs multiple-performance optimization based on the fully virtualized cloud native architecture, improving the user plane processing capability under the hardware resources, which helps to improve the customer's investment efficiency. • Make optimization based on the virtualization and container to meet the needs of 5G Common Core for deploying resources. • Optimize the performance based on open source virtual switches so that the architecture and interfaces are open. • Improve the performance of the forward plane by using multiple optimization methods to meet the requirement for carrier-class network performance.
