¿µ¹®³»¿ë¿ä¾à This document introduces APIs of context-aware system based on USN for application developers and functions of context-aware system. The purpose of context-aware system is collecting a context information and delivers it to applications. Applications registers rule that can take a context information that application wants. Sensor aggregators make a context information by sensing a physical information and register it in context-aware system. Context-aware system finds a rule that application registeres and sends a context information to application. Application receives a context information and then provides some services. There are different rule formats and different ways to get a context information, it needs an unified simple way to make a rule and get a context information.
