The mobile web service according to the preferred embodiment of the present invention displays XML (eXtensible Markup Language) as basic data, and defines a message format through a Remote Pocedure Call (RPC) called Simple Object Access Protocol (SOAP), which is a data encoding standard. Use a protocol. The language describing mobile web services is WSDL (Web Service Descripition Language), which utilizes Universal Descripition, Discovery & Interaction (UDDI) as a kind of directory service for publishing and exploring data. In other words, mobile web services are programmable application logic that can be accessed using standard Internet protocols in the application layer, such as HTTP. For example, mobile web services are Web sites that can provide services between agent programs. The framework processor for a typical XML web service first looks up the XML web service provider in UDDI via SOAP, locates the WSDL, looks up the definition of the XML web service, and then enters or calculates the required definition. Calling a web service provider provides an XML web service.

The mobile communication terminal 110 according to the preferred embodiment of the present invention accesses the web service gateway 120 through wireless network communication, requests and receives web service information from the web service gateway 120 using XML and SOAP. And stores a web service list including a provision request web service, requests and receives a provision request web service from the web service gateway 120, and displays the received web service through an LCD display and a speaker.

XML is a standardized text format designed to deliver structured documents on the Web and is the core technology for Web services. XML is used to define the form of the document. Since tags can be defined by the user, it is possible to standardize the form of data between communication terminals.

SOAP is a communication protocol for XML Web services. SOAP is a specification that defines the XML format for a message, that is, part of a requested specification. SOAP also describes how to represent program data in XML to perform remote procedure calls using SOAP. SOAP also supports document-style applications where SOAP messages only wrapper the XML document. Document style SOAP applications are very flexible. SOAP also defines the format of HTTP messages, including SOAP messages. SOAP is also a technology for standardizing distributed systems to standardize the data passed between XML applications. SOAP is a superset of XML-RPC. SOAP also supports asynchronous invocation and other protocols such as HTTP and SMTP.
