A system includes a context manager that stores, as a device catalog in a storage unit, attribute information and execution condition of a device from which an application acquires context information to execute a predetermined function and that selects a device which the application uses responsive to a request from the application. The application sends a collection policy of the context information relating a device which the application uses to the context manager. The context manager selects a device complying with the collection policy based on the collection policy from the application side and the attribute information and execution condition of the device stored in the device catalog. Upon receiving a context collection request from the application, the context manager provides the application with the context information collected by the selected device.
