A Mobile Service Gateway for Mobile Access to Enterprise Data and Services

We present the architecture of an enterprise mobile service gateway for secure mobile access to distributed, autonomous, and heterogeneous enterprise data and services using browser-based thin-client. Our goal is to address key issues associated with mobile access to enterprise information, while minimizing the cost of service integration by leveraging existing infrastructure and business applications. Our approach achieves high extensibility and interoperability through Web Services based integration scheme and modularized device and gateway adaptation. The security and firewall issues are addressed through the loose coupling between the mobile service gateway and enterprise applications, the separation of mobile proxy and presentation server, and the two-way access control. The combination of home-deck browsing, notification, click-to-dial, and speech access interaction paradigms alleviates the limitations of small keypad and display and brings mobile users rich and personalized user experience. A prototype system has been implemented to demonstrate the significance of cost-effective mobile extension of enterprise services using our approach.
