Abstract (in Japanese) (See Japanese page) 
(in English) NGN has the service platform, which provides some functions to support high-reliability and high-quality services. Our group have been researching and developing one function of the service platform called as "Presence Monitoring System." This system is the Web service that delivers the user's status, which are described as SIP messages, to service providers. For this system, the most important issue is the performance issue, especially, the performance of message transformation from SIP message to SOAP message. This paper proposes "two-step message transformation scheme." On this scheme, a SIP message is transformed to a SOAP message template, at first. And then, SOAP messages for each service providers are created from the template. This scheme can enhance the performance when delivering a user's status to many service providers.
