Management Information Modeling and Realization Mechanism for Ubiquitous Terminal Service

While current researches on terminal information model could not provide enough support for Ubiquitous Terminal Service (UTS) in respect of information, requirements and modeling method for management information in UTS are studied. According to the method, a generic management information model for UTS is established. The model could make up for the shortage of current terminal information model by adopting hierarchical domain, providing management information through device, network, service to customer level, and showing the relationship between those information. A realization mechanism for intelligence and individuation UTS is given with model-based reasoning. The modeling method and the mechanism are verified with a typical ubiquitous service. The results show that the information model can extract all kinds of managed resources and can be used as a basis to provide individualized UTS under heterogeneous terminal environments.
