In this paper, we design an intelligent system architecture for dealing with context-aware application services in ubiquitous computing. The intelligent system architecture is composed of middleware, context server, and client. The middleware component of our intelligent system architecture plays an important role in recognizing a moving node with mobility by using a Bluetooth wireless communication technology as well as in executing an appropriate execution module according to the context acquired from a context server. The context server functions as a manager that efficiently stores into the database server context information, such as user's current status, physical environment, and resources of a computing system. To verify the usefulness of our intelligent system architecture, we finally develop a context-aware application system base on it, which provides users with a music playing service in ubiquitous computing environment.
