Summary: | The invention provides a multi-edge service cache scheduling method and system considering dynamic topology, and belongs to the technical field of edge networks. Based on the defect that a current multi-base-station edge caching method neglects the dynamic change of an edge server, a graph convolutional neural network and deep reinforcement learning are introduced into a multi-edge service caching problem, and the graph convolutional neural network can realize real-time information capture of dynamic topology; information subjected to feature extraction is transmitted to a deep reinforcement learning network for learning, and by combining the strong decision-making capability of deep reinforcement learning, cache decision can be well realized and service stability can be improved.
