Model driven context awareness

University essay from KTH/Kommunikationssystem, CoS

Abstract:

The very nature of mobile phones makes them ideal vehicles to study both individuals and organizations: people habitually carry a mobile phone with them and use it as a medium for much of their communication. The information available from today's phones includes the user's location, people nearby, and communication (call and SMS logs), as well as application usage and phone status (idle, charging, and so on).

The main goal of this project is to combine some of the new technologies of voice over IP (VoIP) with context awareness services for mobile users and create a demonstrator for a typical routine of a student in Kista.

We used context awareness together with the SIP Express Router to make a system more intelligent for the user. In this thesis the definition of CPL scripts and how they could exploit context information to provide SIP service that would be useful to a student were examined. A simple test was conducted to measure the overhead of using context awareness by the SIP proxy when processing CPL scripts.
