Description

Digital twin-drive-based multichannel converged network communication simulation deduction method and system Technical Field The invention relates to the technical field of network communication and digital twin, in particular to a multichannel fusion network communication simulation deduction method and system based on digital twin driving. Background With the rapid convergence of wireless communication, satellite communication, optical fiber communication and various heterogeneous networks in application fields, multichannel parallel communication has become a main technical direction of enhancing reliability, improving bandwidth and guaranteeing continuity of key services of modern communication systems. In the scenes of mobile communication, complex industrial network, emergency communication guarantee, unmanned system cooperative communication and the like, a communication link is always in a dynamic change state, and the channel quality can be influenced by multiple factors such as mobile environment, shielding structure, interference source change, service load fluctuation and the like. The existing network simulation technology generally relies on a preset model or static scene data to carry out communication calculation, and is difficult to meet simulation requirements of real-time performance, high dynamic performance and complex interaction behaviors in a multi-channel fusion system. In recent years, digital twin technology has been introduced in the field of communications for constructing virtual mirror models that map the state of a real communication system. The digital twin model can provide a relatively real reference for communication performance analysis and path formulation by digitally presenting communication nodes, link states, topology changes and environmental factors. However, the existing digital twin communication model still mainly stays at the level of 'real-time mapping' or 'near real-time simulation', and has the core function of reproducing the current state or analyzing the short-term trend, and cannot realize the prospective deduction of the future communication situation. Specifically, the prior art mainly has the following disadvantages: First, lack of future-oriented predictive capability: most of the existing communication simulation is 'current state reproduction', and the changes of channel fading, node movement, interference increase or service peak value and the like in a period of time in the future cannot be predicted according to the development trend of a physical scene, so that a communication path cannot be formulated in advance. Second, no deduction can be made for future multi-scene evolution: the current system is more based on fixed parameters or a small number of static configurations for simulation, and has no ability to construct multiple possible future evolution paths in digital twin virtual space for deduction, such as high load burst, rapid occlusion change, severe environmental disturbance, etc. Third, the multi-channel fusion path lacks foresight: Existing multi-channel fusion methods typically make decisions based on current instantaneous link quality, but link behavior tends to have significant time correlation and trends, which make current paths difficult to accommodate for impending changes, resulting in frequent handoffs, path lags, or unreasonable resource allocation. Fourth, emulation-driven communication regulation cannot form a closed loop: The existing simulation and real communication system has limited interaction modes, is mostly configured and adjusted by means of manual analysis results, and lacks a mechanism capable of returning deduction information to a physical system to form an automatic regulation closed loop. Fifth, the evolution capability of the digital twin model is insufficient: Most of the existing digital twin communication models are built by depending on fixed scenes, and model parameters, channel characteristics and environment data are not updated timely enough, so that long-term evolution rules or abrupt change behaviors of the communication environment are difficult to reflect. Based on the above problems, the prior art cannot support the future-oriented network communication deduction, path advanced planning and active regulation and control capability of the multi-channel fusion system. In the highly dynamic, complex and changeable application scene, the technical scheme which has the prediction capability, can carry out future state simulation deduction and can drive a physical system to carry out real-time path optimization is lacking. Therefore, a multi-channel fusion network communication simulation deduction method and a system based on digital twin driving are provided. Disclosure of Invention The invention aims to provide a digital twin-drive-based multichannel fusion network communication simulation deduction method and a digital twin-drive-based multichannel fusion network communication simulation ded
