5G URLLC Local Deployment Architecture for Industrial TSN Services

In the industrial scenario, the requirements for network quality and data security of industrial Time Sensitive Network (TSN) services are becoming more and more stringent. 5G technology has the characteristics of wide bandwidth, low latency, and massive connections. Mobile Edge Computing (MEC) can improve the utilization of resources and the security of data, while future reducing the transmission delay. However, for industrial TSN services, a new network deployment architecture is still needed to provide reliable, flexible, and secure services for the industrial Internet. This paper proposes a local deployment architecture and adopts a deployment optimization scheme of Distributed Unit/ Centralized Unit/ User Plane Function/ TSN Translator (DU/CU/UPF/TT) convergence integration, highly integrated network elements, build DU/CU/UPF/TT compact integrated equipment, realize the idea of the separation of control plane and user plane, and realize efficient data forwarding. Meanwhile, some technologies such as Multiple-transmission/Reception Point (Multi-TRP) and New Radio Dual Connectivity (NR-DC) are used to meet the requirements of the low latency of industrial TSN services, and ensure data security and improve network quality.
