Abstract	Mobile broadband is one of the most common ways of connecting to the Internet. A mobile broadband network is stateful, and a device is allocated different radio resources depending on the state. State promotions take up to three seconds, and the promotions, or just being in the "wrong" state, can have a severe effect on user experience. Existing work has mostly focused on optimising state changes in order to reduce resource usage in the network, as well as battery consumption on devices. In this paper, we look at how explicitly requesting state promotions can be used to improve application performance. Our technique is evaluated using an application that retrieves data through the common HTTP protocol, in real-world 3G networks. We show that by preempting state changes, the delay caused by state promotions are removed and the transfer time is significantly reduced.
