Mobile data offloading service using file cloud in small cells

Recently, lots of mobile operators have deployed small cells in their 3G/4G mobile networks for network densification to deal with the exponential mobile traffic growth. This paper shows a way to provide file data offloading service to mobile users by utilizing the small cell system. Users can handle files of big size on their phones interacting with the file cloud server of the near small cell. Therefore, mobile data can be offloaded from mobile core network to the small cell. In addition, the file cloud service has file expiration mechanism due to nomadic characteristics of small cell users. This paper describes how to provide file data offloading to mobile phone users through the file cloud services on small cells.
