to design, develop, evaluate and prototype an extendable overlay architecture and framework that supports
Easy and quick service creation of intelligent and ambient-aware services
Cooperation of multiple heterogeneous execution environments
Pan-European seamless delivery of services across operator domains, networks and terminals
SPICE scenarios The tourists’ potential interest in particular activities or items is inferred from their behaviour and is followed by a service push. So when they stop around for a couple of hours at a nice village in the countryside the system advances a proposal suitable to the moment of the day (“do you want suggestions for a light meal nearby?”). Depending on the user’s reply, additional audio/visual information is provided to get them on the suggested spot. Once they have enjoyed the break, they go back to their car … A multidisciplinary team of managerial, marketing and technical people associated with the promoting organization of “Sunrise Inc.” and its technology partners meet to evaluate all the possibilities offered by the SPICE PF components repository. Some services will be created by simply reusing existing elements (e.g. basic components, composite components), while others will be realized as an investment from the involved third parties. Ad hoc contractual and operational models are provided ….

Decrease to a few scenes the explicit reference to proactive mechanism altogether
• Link clearly the delivery of proactive suggestions to some user action or previous declaration
• Explain more about the Semantic Language
• Clarify what the emergency service is
Mapping users’ input into “scenes’ requirements”
Enhanced scenarios it is impossible that the service makes use of users’ sensitive information in a malicious way since the local SPICE Operator guarantees that user’s personal data (e.g. name, address, mail, telephone…) are never matched with his context information (e.g. position, mood, availability). Before the service can use sensitive information, the user’s consent must always be given.
