Summary on Grant Application Form
The project will investigate the application of policy-based management to support context-aware services for 3G mobile networks at three levels: (i) within a middleware layer interposed between network and service; (ii) at service administrator level; and (iii) at user level. A major part will be dedicated to investigating and realising a middleware system for service management and to looking into ways of equipping it with a policy-based management engine. This involves the development of an information model which allows the representation and manipulation through policies of context-aware services; the specification and realisation of a core set of middleware functionality which provide sufficient support to user and service administrator; and the specification and realisation of middleware functionality to efficiently gather the 'context' (i.e. network QoS, terminal capability, terminal location, time and user profile). The middleware policy engine includes means for policy validation, conflict detection and resolution, exception handling and adaptation. Access to these capability through a well-defined set of APIs aims at facilitating the development advanced context-aware, adaptable applications. Another important part of the project will investigate policy-based tools to interface both the service administrator and the user with the middleware, facilitating service configuration and customisation through a high-level policy or rule-based XML interface. Tools, middleware and information model will be validated and evaluated experimentally and will be finally demonstrated through a context-aware service.
