Service-oriented architecture to mobile phones

New business opportunities are being enlarged by mobile phones. Electronic commerce on mobile phones is an emerging expression of internet electronic commerce to provide sophisticated services to mobile users. The Web services technology has been proposed to support electronic commerce on wired networks. However, no significant research has been done to allow mobile phones acting as Web services requestor at runtime without prior knowledge of available services. In this paper, we propose a service oriented architecture to mobile phones. We introduce service managers as proxies between services providers and mobile devices in order to solve the limitations faced by direct access from mobile devices to Web services. We investigate the use of dynamic invocation interface as communication mechanism between service providers and service managers in order to compute service description and invocation at runtime. With this approach, we allow that service providers to create, update and change services at anytime and mobile users may locate new services without knowing the accessible services. We have implemented a first prototype with open source tools and basic service scenarios.
