To offer a semantically suitable service for user in context-aware system, ontology concept is needed. By using the ontology, it is possible to provide knowledge sharing and support for syntactic and semantic interoperability. In this paper, we propose the context-aware service engine based on ontology. As we use ontology, our system has the following useful aspects. First, our system can describe types, hierarchies, relations of contexts, so that any context instance can be accommodated into the system with no additional effort. Seconds, as we design two level's ontology, any system which uses ontology could reuse our context ontology context in pervasive environment. Three, our system could be applied to semantic Web which is called a revolution of a post Web and could provide interoperability
