Mobile devices are increasing in an astronomical rate throughout the world. While it is bringing a lot of comfort to the users it is not coming without any hazards. Now a user is susceptible to mobile call interruptions wherever he is, whether he is in the middle of a very important discussion or in a very important task like performing a complicated emergency operation in a hospital. As a result researchers have been studying to find ways to minimize cost of mobile interruptions. In this thesis we have proposed a mobile interruption management system in which callers have been grouped and time intervals of a day have been classified to ascertain whether a call should be allowed to ring, go silent or vibrate. We have also included presence of Bluetooth devices and applications the mobile user is using to decide if the user needs to be interrupted. We have undertaken a survey of mobile users to compare various models and select appropriate default parameter values like caller groups, time intervals, and inclusion of special days/events. We have proposed a matrix containing default values of cost of mobile interruption, which will be adjusted according to contexts the user is in and then this cost is compared with the threshold value. If the cost of receiving the call is less than the threshold value, then device sound profile is set to ring or vibrate otherwise it is set to silent. We have also evaluated our model with existing models and found the system performing well.
