Embodiments of the present invention disclose a content delivery method, including: when a content request of user equipment UE is received, acquiring location information of access of the UE; acquiring at least one content control apparatus and information about a first area that can be served by the at least one content control apparatus; determining, according to the location information and the information about the first area, a content control apparatus for serving the UE; sending a request for searching for a cache cache device to the determined content control apparatus, where the cache device is configured to provide content requested by the UE; receiving an identifier of a cache device returned by the content control apparatus; and sending a redirection message to the UE, so that the UE redirects to the cache device corresponding to the identifier to acquire the requested content. In the present invention, a data interaction path between UE and a cache device is shortened, which reduces transmission bandwidth of an operator network, thereby improving user experience. In addition, a content delivery apparatus controls whether to select a cache device of a network service provider to serve the UE, that is, a CP/SP controls whether to select a cache device of the NSP to serve the UE, thereby implementing layered control for a CDN. In addition, cache resources of the network service provider can be open to the content provider or the service provider, thereby implementing monetization processing of the cache resources and increasing income of the network service provider. |
