Heterogeneous 5G Multi-Path Fusion Secure Networking Technology for High-Reliability Power Grid Service Transmission

Abstract

Targeting the two typical scenarios of emergency repair and the commissioning of newly built substations in power grids, existing single-operator 5G communication is fraught with pain points such as network congestion, link interruption, and lagging deployment of wired channels, rendering it incapable of satisfying the requirements for high-reliability, high-priority, and high-security service transmission in the power sector. This paper proposes a heterogeneous 5G multi-path fusion secure networking technology oriented towards high-reliability power grid services. It constructs a concurrent access architecture for multi-operator 5G networks, develops portable multi-network fusion hardware terminals for power services, and concurrently implements a lightweight secure encrypted transmission strategy. Through practical validation, compared with the traditional single-operator 5G scheme, the proposed approach achieves a 200% improvement in communication rate, a 92.9% reduction in transmission delay, and a 90% decrease in maximum packet loss rate, demonstrating broad applicability in scenarios such as power disaster emergencies and grid expansion construction.
