Abstract
A method for delivering video data from a server in a content delivery network (CDN). Video preferences of active users of a cell are determined. Video data is cached at one or more base station nodes disposed in a radio access network (RAN), wherein the video data is cached in one or more micro-caches according to a caching policy that is based on the determined video preferences. A request is received for video data. If the cached video data includes the requested video data, the cached video data is served from the RAN cache. If the cached video data does not include the requested video data, the requested video is fetched from the CDN according to a scheduling approach that considers Quality of Experience (QoE).
