Location-based-service roaming based on Web services

Due to the rapid growth of personal mobile communication devices, more and more wireless mobile applications are developed. Location-based mobile application, one of the wireless mobile applications, becomes the future trend. However, the application execution environment is not complete. How to integrate the services among multiple telecommunication service providers? How to support the original location-based services for the mobile roaming users? This project is aimed at solving these problems efficiently. This paper proposes to integrate the roaming services into Web services infrastructure. In this case, the mobile users could get the location-based service during roaming. Integrating the location-based application into the Web services also solves the mobile roaming problem.
