摘要： Embodiments of the present invention provide a method, device and system for obtaining data resources of a mobile network. The method for obtaining data resources provided by the present invention includes: receiving, by a first base station, an obtaining request sent by a mobile terminal, wherein the obtaining request includes description information of a data resource requested to obtain; if the first base station determines that the data resource corresponding to the description information is not stored in a local cache, sending the obtaining request to a second base station, wherein a local cache of the second base station stores the data resource; receiving, by the first base station, the data resource corresponding to the description information sent by the second base station, and sending, the data resource to the mobile terminal. Embodiments of the present invention can prevent the problem that a lot of network uplink bandwidth is occupied after P2P transmission mechanism is introduced into a mobile network.
