Abstract: The goal of the ubiquitous convergent network is to provide the dynamicly adaptive and context- awareness pervasive services. However, the existing telecommunication service opening architecture based on the traditional distributed computing technologies is unable to meet the development trends and characteristics of the future user-centric intelligent convergent services. This paper presents the great changes of user-centric convergent service provision pattern. And then the semantic interoperability-enabled user-centric convergent service architecture and key technologies are proposed. This approach can seamlessly integrate the telecommunications and Internet services in the semantic level and then create a virtual convergent service computing environment.
