Mobile service provision system based on sensor and SIP event notification mechanism

As the users need to take a mobile service while roaming around increases, many solutions are needed to figure out the users current location and service information and prepare subscribed mobile service without users intervention. We propose a mobile service provision system, which is based on sensor and SIP-specific event notification mechanism. In this system, dynamically subscribed service terminal is selected and used to provide mobile service to a roaming user by a sensor-equipped user agent which is also interworking with 3GPP IMS for getting extended user profile stored in HSS. And this user profile, capability report and command script which are used in our system are all XML-based documents, so these can also be easily modified and applied to any other services.
