【正文】 r mobile devices or desktop PCs on a wired/wireless integrated local area work using WSDL (Web Service Description Language) to describe functions and protocols. The web server then transmits to the mobile devices or desktop PCs. The user binds the web server and the WSDL. This enables the web service to be used by correspondence using SOAP (Simple Object Access Protocol). The database server saves all information of the system such as food information, ordering information, client information. The cash register is responsible for cost calculation of the consumer. The mobile context server applies context to the contents by using styles, an attribute override, and templates according to the resources of a given mobile device. Desktop users can ask for services after checking the WSDL of the service from the web server. A desktop on a wired work can be used to browse full contents on one screen shot. When a user requests food information through a wired work, the web server serves the information by connecting to the database server. When a user requests food information through a wireless work, the mobile context server divides the context pages according to the screen size of the mobile device. It also filters the pages according to mobile devices and then browses the adopted content from the context server to the mobile web browser. The mobile context server reconfigures contents offered by the web server. Figure 1 The System Architecture B. Web Service Security Model Web service security can be applied at three levels : ? Platform/transportlevel (pointtopoint) security。 附錄 A Wireless Food Ordering System Based on Web Service Abstract—Current wireless munications enable people to easily exchange information, while web services provide looselycoupled and platformindependent ways of linking applications across the Inter or Intra. This paper presents an integration of wireless munication technologies and web services technologies to realize a wireless food ordering system. In this system, it implements wired and wireless data access to the servers and food ordering functions through both desktop PCs and mobile devices such as PDAs over a wired/wireless integrated local area work. To sure the security of the system, the secure web service architecture and some security strategies to ensure mobile munication security are discussed. Web servicesbased wireless applications on mobile devices provide a means of convenience, improving efficiency and accuracy for restaurants by saving time, reducing human errors, etc. Keywords Web Services。 ?
