In order to bring together the different advantages of various wireless technologies and wired networks, solution from service's perspective is critical. And this kind of integrated services should be context-aware in order to automatically adapt themselves to the changing environment. This paper proposes an all-policy based context-aware service method for next generation networks (NGN). Policies are planned to cover the full context representation through services and the underlying networks. The efficiency of context-aware service provisioning as a result of policy decision is maximized by the introduction of mobile agents. A context-aware service scenario called Super-mother is explored to exemplify this methodology and policy-based context-aware service system architecture. This paper presented part of the work ongoing in European Union IST project CONTEXT.
