Context aware system provides a process of context acquisition and reasoning to the context-aware service and enables developers to implement of these applications easily. Unfortunately, previous studies have not been able to support the user mobility, nor the service mobility efficiently. Both, however, should be supported in a ubiquitous computing environment. Therefore, this study proposes a dynamic context aware service model, which supports the management of context information and service mobility among service gateware. We also have designed a middleware based on this model. As the middleware is implemented on the OSGi framework, it can cause inter-operability among devices such as computers, PDAs, home appliances and sensors. The proposed middleware has advantages of interoperation and integrating the heterogeneous devices by applying these standard interface technologies to this middleware.
