Distributed context management: Architecture & commercial trials

This paper presents the design of a Context Management Architecture. It introduces a modular and extendible management model comprising Context Broker, Context Provider and Context Consumer entities. In addition, Service Enabler components are introduced. By descriptive commercial trials and usage scenarios its success is documented. The architecture proves its ability to support a large variety of contextual information. Hence, it is suited for multi-domain context-aware communication systems and evolves by adding new context scopes during runtime.
