Energy-constrained smartphones and operation-facilitated tablets are popular and necessary in our daily life, and people may prefer to use tablet to access smartphone's features for energy efficiency and easy operation. In this paper, we present uPhone, an energy-efficient framework for ubiquitous phone access that allows ubiquitous and symmetric access to a smartphone's core features via a third device such as a tablet. More specifically, we design uPhone in two main components of devices and uPhone server, then implement it on a smartphone as a primary device and a tablet as a secondary device, and finally evaluate it in terms of energy savings, latency, and reliability. The evaluation results demonstrate that uPhone achieves up to 44% energy savings compared with simply typing and sending messages, and notifies on a smartphone, incurs little latency overhead that is acceptable by users, and performs roughly equivalent to standard messages with a high-quality user experience.
