The flexible access to offers, information and services is provided through so-called open service platforms in the city of tomorrow.

These open service platforms are based on convergent, heterogeneous network technologies, for example wireless and wired telecommunication networks, next generation networks (NGNs), and the Internet. In addition, the current development in line with a „future internet“ will have a lasting effect on municipal networks and service platforms in the areas’ transfer rates, safety and service variety.

Researchers at Fraunhofer FOKUS for example are realizing the scenarios of the German administration hotline 115 based on the IP multimedia subsystem (IMS) for different media access channels. This allows for service requests to be automatically transferred even to back office systems. In addition, all information in regards to processes, responsibilities and back office processes is organized in local knowledge centers that can be logically linked in order to create subordinated or area-wide knowledge centers.

The intelligence of wireless access networks and their further development are currently concentrated in the evolved packet core (EPC). The EPC follows the evolution of wired core networks and the occurrence of overlay control networks like the IMS. The Fraunhofer FOKUS EPC system is used by operators worldwide and is currently being enhanced.
