Abstract: With the growing complexity of electric-power telecommunication networks, alarm messages have surged, challenging operation and maintenance. Traditional methods overlook spatio-temporal characteristics, hindering root cause identification and fault propagation analysis. This paper proposes a spatio-temporal graph neural network-based alarm analysis method, extracting spatial and temporal features to construct a graph model and node alarm subtrees based on alarm propagation. Subtree features incorporate node relationships and alarm rules for accurate analysis. To reduce computational overhead from model parameters, a swarm intelligence optimisation-based lightweight technique is introduced, enhancing deployment efficiency in resource-constrained environments. Experiments demonstrate superior performance in alarm correlation accuracy, compression, and fault localisation compared to traditional methods. The approach effectively minimises redundant alarms, boosts maintenance efficiency, and supports intelligent network operation.

Keywords: electric-power telecommunication network; spatio-temporal graph neural network; alarm subtree; particle swarm optimisation; PSO.
