Design and implementation of u-service manager in open service framework

User centric service in mobile environment has become a new issue in the area of service convergence with the advent of versatile mobile devices. We propose an open service framework with support for service mobility that executes contents and applications in a dynamic environment. We put emphasis on u-service manager of the open service framework in this paper. For the u-service manager, mechanisms for device profiling, user preference learning, and profile-based service recommendation are designed to enable device-capability-aware service recommendation functionality. A prototype system integrates functionalities with proprietary protocol to support multiple device platforms. The prototype shows the capability of the u-service manager that controls service sessions in real-time under service mobility. Also it shows that the u-service manager provides the dynamic configuration environment appropriate to the user and the targeted terminal device.
