Edge collaborative content caching method and device, equipment and storage medium

The invention provides an edge collaborative content caching method and device, equipment and a storage medium. The method comprises the steps of obtaining business preference data of each service vehicle in a collaborative caching domain; inputting the historical preference data into a federal prediction model to obtain a component demand prediction result; the federated prediction model is obtained by performing federated learning training based on historical preference data of each service vehicle in an edge node in a cooperative cache domain; and on the basis of the component demand prediction result, calculating to obtain a global optimal pre-caching strategy so as to cache the pre-caching component of the global optimal pre-caching strategy to the edge node. The vehicle service component demand is predicted through the federal prediction model, leakage of vehicle privacy data is effectively avoided, and based on the component demand prediction result, the optimal pre-caching strategy is calculated to pr
