Modeling Context Information for Realizing Simple Mobile Services

The emerging technology of mobile services is gaining on importance nowadays and various applications are being developed. Context-awareness constitutes an essential part of mobile services, as it can boost the provision of new personalized services (e.g. location based services). In this paper, the concept of a UML-based context model for the Simple Mobile Services (SMS) project is presented. The SMS Context Model focuses on modeling context information in a structured and comprehensible way in order to facilitate the development, provision and operation of context-aware mobile services. Its three-level approach (meta, model and instance) offers different levels of abstraction and can be used as a basis for transforming the resulting model to various implementation languages.
