WEB SERVICE CHARGING SYSTEM FOR QOS GUARANTEE AND METHOD THEREOF

摘要

A web service charging system for QoS guarantee and a method thereof are provided to improve a service and guarantee reliability for the service based on a charging policy for providing a service according to service QoS. A service providing server(200) provides a client(100), connected through a network, with a chargeable web service. A UDDI(Universal Description Discovery and Integration) server(300) stores and indexes information about a web service which the service providing server provides through a UDDI registry. The UDDI server relays the stored and indexed information to the client, and supports web service selection of the client. In the UDDI server, a registry unit(310) performs a function of the UDDI registry, receives contents of a web service provided by the service providing server, and notifies the received contents to the client. An accounting manager(320) receives charging policy information or QoS(Quality of Service) status information or web service status information from the service providing server, and determines a charging level. A QoS broker unit(330) receives the charging policy information or QoS status information or web service status information through the accounting manager, and measures a QoS status for the web service to provide information about the web service to the client.
