[[alternative]]A Study on Functional Structure of Mobile Phone

[[abstract]]Through the increasing variety of mobile phone capabilities, people can characterize their mobile phone more to show their characteristic such as ring settings, color covers, etc. What if they could characterize the capabilities of their mobile phone?
