The disclosure relates to a method for sending a message, an access router, and a data cache system. The method for sending a message includes: sending a data request received by the access router to a gateway node in the home routing area of the access router; receiving location information from the gateway node, where the location information identifies a data cache node obtained according to the data request, and obtaining information about the cost of routing from the access router to the data cache node according to the location information; and sending a data obtaining request to the data cache node, where the data obtaining request carries the routing cost information. The method for sending a message, the access router, and the data cache system provided herein utilize the radio bandwidth efficiently and improve the network throughput.
