The project addresses the strategic objective of "Mobile and Wireless Systems Beyond 3G". The Ambient Networks project will create the network solutions for mobile and wireless systems beyond 3G. It will enable scalable and affordable wireless networking while providing rich and easy to use communication services for all. It is geared towards increasing competition and cooperation in an environment populated by a multitude of user devices, wireless technologies, network operators and business actors.

Technical solutions for all of them already exist today but their systems are more or less isolated from each other. The shown Ambient Network environment however augments this isolated status to an overall communication system. This does not only include the technical interfaces in that heterogeneous infrastructure but also the commercial aspects. A user is identified by his individual ID (regardless of the terminal he uses), which allows access to all network types to which he has subscribed.

Initially each wagon has its own Ambient Network, but as they are linked, they compose and merge into new Ambient Networks. When a new network component is added to an existing AN, such as an access point, a case of Plug-and-Play (PnP) rather than network composition occurs. As the rock band’s exclusive wagon is attached to the rest of the train, its own Ambient Network composes with the Ambient Network of the rest of the train. Since these two Ambient Networks have different authorities, this follows what is entitled a gatewaying composition model. As they compose, they exchange information such as their network sizes and available resources. “Rock Express” Storyline 1

There are several levels of hierarchy, where the fans’ Ambient Networks can connect to the train-ground Ambient Network. They might use the ANI to connect to the public wagons Ambient Network. Alternatively if they have VIP privileges, they might become part of the rockband’s wagon Ambient Network, through absorption. During the concert performance, a base station providing a live feed to a TV network fails. The Ambient Network dynamically recomposes and reroutes traffic through another base station while preserving QoS levels through traffic engineering methods. “Rock Express” Storyline 2

When the Rock Express has not reached the station yet, the management station does not take it into consideration. When the train arrives, the pattern-based network monitoring system adapts to include the Rock Express in the set of monitored objects. At this point, the station network operator starts getting near real-time connectivity information from the Rock Express. Finally, the monitoring system adapts to the departure of the train. During the journey between different concert places, the Rock Express train gets network connectivity using different access Ambient Networks. “Rock Express” Storyline 3
