Intelligent Service Enabler Based on Context-Aware in Next Generation Networks

Digitalization of various kinds of information is accelerating the convergence between them by fast development of network technology. Service provision also has been advanced because the convergence of information is becoming easy. And there are many researches to realize context-aware services that recognize users and devices environments based on context-aware computing technology in order to provisioning the intelligent service. In this paper, we show a variety of context information of device, network, user, position, and mobility in heterogeneous networks based on IMS (IP multimedia subsystem) and present structure and function of context-aware system for IMS service enabler. The context-aware system decides appropriate services that are the most suitable according to circumstance information in the Ontology.
