Study of context-aware phone communication strategy

The commonly used phone communication is designed on the assumption that caller actively telephones callee without any knowledge of callee's situation. Along with the development of computing and sensor technology, context information of user can be sensed, inferred from pervasive environment. Caller can determine in what situation callee locates with context information of callee. Some research work shows that caller uses this context information for presence instead of availability. That is, caller may make a phone communication while callee is in unavailable state. It still brings callee interruptible even if context information of callee is shared. Exposing context information to caller is also privacy concern of callee. In order to solve these problems, a communication strategy between caller and callee is proposed to reduce callee's interruption and enhance callee's privacy. We validate the communication strategy with the real communication history data.
