13. Secure Systems Research Group - FAU Conclusions Context is a fundamental concept in mobile systems. Different researchers use different variations of context. Web services is the widespread approach to application integration. Integrate Web Services into our Context Model for easier application integration. Create a Context Architecture incorporating WS.
