基于MCData的低空C2指控链路研究
Research on Low-Altitude C2 Link Based on MCData
摘要
Abstract
The low-altitude airspace features the co-existence of multiple wireless networking methods,encompassing public networks,low-altitude private networks and satellite communication systems.Based on the 3GPP Mission Critical Data(MCData)protocol,this paper designs a C2(Command and Control)communication link solution which integrates airborne multi-mode communication terminals with ground-based multi-protocol communication gateways,leveraging the service-and-bearer separation mechanism under the IMS architecture,as well as OAuth2.0 unified authentication and SIP registration technologies.It supports automatic discovery of multi-protocol network,adaptive switching and fused offloading,and enables end-to-end data priority management and multi-layered security protection.This design provides low-latency,high-reliability,and high-security communication guarantees for low-altitude mission-critical operations,such as data transmission related to C2 commands and monitoring status between the flight control system and ground control center of Unmanned Aerial Vehicles(UAVs).关键词
