This invention relates to an automatic configuration and recovery method for communication radio frequency units, specifically in the field of communications. This method constructs a dynamic graph integrating configuration, performance, and topology relationships, and utilizes a spatiotemporal graph neural network to learn a network health benchmark. This enables the automatic discovery of implicit parameter conflicts introduced by manual configuration. Its community-based subgraph partitioning and consistency evaluation mechanism can accurately locate abnormal radio frequency unit groups causing performance degradation. By simulating and evaluating multiple repair schemes in parallel within a digital twin environment, the optimality and security of the recovery decision are ensured. Ultimately, a complete closed loop is formed from intelligent detection, precise location, simulation optimization to secure execution, significantly improving the automation level and problem-solving efficiency of network operation and maintenance, and effectively avoiding chronic performance degradation caused by configuration errors.
