A Context-Aware Phone Communication Strategy Based on Availability of Callee

Traditional phone communication is designed on the assumption that caller actively telephones callee without any knowledge of callee´s situation. Caller often doesn´t make successful calling as callee is not available at that time. Along with the development of pervasive computing and sensor technology, context information of user can be sensed, inferred from pervasive environment. Before starting a phone communication, caller can determine in what situation callee locates with context information of callee. A communication strategy between caller and callee is proposed to reduce callee´s interruption and enhance callee´s privacy. For the minimum of callee´s decision burden from the proposed communication strategy, we use rough set theory to extract callee´s phone communication pattern for the automatic phone communication decision.
