In ubiquitous environments, location-based context awareness service provides additional services based on a user's location. In this paper, we design a context awareness inference engine model for working environment monitoring system of mobile object which is an issue in location-based application. We in the proposed a context awareness inference engine can use sensors, mobile communication network in order to achieve working environment information of mobile object. The proposed framework is consisted of data collector, context manager, knowledge base, inference engine, and context database. And it also has a structure that enables to serve users by embodying context awareness application interface for particular application.
