WIPO Patent Application WO/2019/095402
Kind Code:
A1
Abstract:
A content popularity prediction-based edge cache system and a method therefor, comprising the following steps: (1) offline training a preference model for users within a training node coverage area on the basis of user history request information; (2) when a request arrives, if the requested content is not found in a cache area, online predicting content popularity on the basis of the user preference model; (3) comparing the sizes of a content popularity prediction value and the lowest cache area content popularity value and making a corresponding cache decision; (4) updating a current moment content popularity value, evaluating the user preference model, and determining whether to activate offline user preference model learning. The system and method allow an edge node to predict online a content popularity, to track in real-time changes in the content popularity, and to make a corresponding cache decision on the basis of the predicted content popularity, thus ensuring that the edge node continuously caches hotspot content and acquires a cache hit rate approaching that of an ideal cache method.
