Next generation services and networks require information and communications systems able to support context-awareness applications and especially pervasive services. This paper present research challenges in context-awareness and context information modelling rules for supporting management operations within pervasive services into the framework of information systems interoperability. Logic-based rules for context information are discussed and studied and then the system architecture for context handling and delivery of context information using logic models is presented. Logic- based information modelling techniques with semantic enrichment are presented as one of the most proper for pervasive applications in the framework of distributed context information handling and delivery for data query-oriented applications. We support the idea of end user‘s applications and the management complexity of such services as well as communications networks, following the states streaked by logic models.
