Data offloading is a technique to transfer data between different networks like mobile network to Wi-Fi networks. Wi-Fi or Wi-max networks are very fast and require no spectrum fees to implement them. Whereas, mobile networks require the spectrum reservations which are highly costly and heavily affect the service charges offered by the cellular service providers. In the authors' proposed scenario, they are using controlled data transfer mechanism to offload data between mobile network and campus wireless network to facilitate the calling facility in the campus for the smart-phone users using wireless network in the campus.
