Implementation of next generation mobile service: The context-aware follow-me service

With the advent of mobile communication technologies, next generation mobile service is evolving toward user-centric services, in that each user can get a personalized mobile service based on his/her needs. In this paper, we propose the context-aware follow me (CAF) service as a prototype next generation user-centric mobile service. The CAF service is designed to provide optimized service based on various context information such as user's location and preference, capability of devices located around a user and characteristics of services in use. We also present an example CAF service scenario, an overall system architecture, a test-bed system and a sample CAF service flows.
