N).

The information communication network refers to a data communication network in a comprehensive sense, which is connected to each other by various networks including a LAN, a WAN, an intranet, and similar internal networks, and provides access to the Internet. It should be understood to include a broadband network (BcN network) as well as a wired network including PSTN) and a wireless network such as mobile communication network, satellite communication network and IMT-2000.

The web service provider 10.N provides its web service program through the information communication network. A web service is a program that is provided through an information communication network, for example, the Internet, so that others can call and use it as a module of software. Invoking a web service performs a task on the system of the web service provider 10.N and returns the result to the caller. The web service provider (10.N) describes the function of a web service in the form of the eXtensible Markup Language (XML) as a web service description language (WSDL), and a WSDL document describes how to call a web service to a user who wants to call the service. This document describes how to use the web service, such as which messages should be received. These WSDL documents are generally registered and published in the UDDI registry so that many consumers can easily access them from the public place. The XML-formatted message is used in a series of processes such as calling the web service and returning a result, and the SOAP protocol is generally used as a protocol for sending and receiving XML messages, but the present invention is not limited thereto.

The end user 20.N is a user who uses the end user service provided through the portal of the BP providing system 100.

The end user service provider 200 develops and provides a service to which the end user 20.N accesses through the portal of the BP providing system 100.

The registration command is sent to the unit 143. The UDDI registry unit 143 receives a BP or web service registration command from the UDDI management unit 142, registers with the BP registry 143.2 or the web service registry 143.3, and then returns the result to the UDDI management unit 142. To send). When the UDDI management unit 142 receives the registration result from the UDDI registry unit 143, the UDDI management unit 142 provides it to the system administrator through the portal server 120.

The UDDI registry unit 143 receives a web service search or registration request from the UDDI management unit 142, searches for or registers the BP registry 143.2 or the web service registry 143.3, and then outputs the result of the UDDI. It transmits to the management part 142. The UDDI registry unit 143 is composed of a UDDI registry interface module 143.1, a BP registry 143.2, and a web service registry 143.3. The BP registry 143.2 or the web service registry 143.3 is a kind of database in which registered BP or web service information is stored. Each service consists of a set of service information structures, including a service provider and a description of the service content. The UDDI registry interface module 143.1 is a module that accesses the BP registry 143.2 or the web service registry 143.3 to actually perform a search or registration, and may be a Java API for XML Registry (JAXR). JAXR provides a convenient way to access business registries such as standard UDDI over the Internet.

The business flow manager 144 is a module that is in charge of performing the called BP. BP defines the exact calling order of web services that participate in the process. Several web services can be called sequentially or simultaneously and in parallel. In some cases, conditional calls can be made to determine whether to call a web service based on the result of a previous call. Such BP can be described as BPEL as described above. BPEL stands for Business Process Execution Language and is a standard language for defining and executing BP in a web service environment. BPEL is based on the XML and Web services. BPEL uses an XML-based language to support the web services technology stack, including SOAP, WSDL, UDDI, and so on. When providing the end user service, the business flow manager 144 performs a function of mapping the BP participating in the interworking of the service to the service.

The service protocol conversion unit 145 converts the received message into the web service protocol used by the SEDAS 140 when calling an external web service using a protocol different from that used by the SEDAS 140 as the web service protocol. In other words, it acts as a kind of gateway that converts the outgoing message into the protocol used by the external web service provider (10.N) and sends it.

The Parlay / X Adapter 146 is an interface that allows access to Web services of the Parlay / X standard.

The web transceiver 147 is a module that is responsible for the transmission and reception of messages transmitted and received through the information communication network, and distributes the received message to each module to be processed, and each module transmits a message to be sent through the information communication network. 147).

The service manager 148 stores the end user service in the end user service list when the portal server 120 requests registration of the end user service, and the end user when the portal server 120 requests registration deletion of the end user service. Deletes the user service from the service list and monitors the performance of BP and web services.

When the service test management unit 149 receives the service test request from the BP developer 101, the service test management unit 149 requests the execution of the requested service to the business flow management unit 144, and analyzes the service execution result received from the business flow management unit 144. The result is provided to the BP developer 101.
