  In the past years there has been significant progress in Intelligent
Transport Systems in the domains of traffic management, driver assistance and
driver information. Within the German research project COmmunication Network
VEhicle Road Global Extension (CONVERGE), a system architecture for the
flexible interaction between different service providers and communication
network operators will be designed and implemented, called Car2X Systems
Network architecture. The Car2X Systems Network will establish a completely new
open communication-, services-, and organization architecture that reflects
state of the art communication technologies and IT security. Through
well-defined access methods, service providers like traffic control centers or
vehicle manufacturers can be integrated into the open and secure system
network. The ultimate goal is the decentralized and dynamic coupling of all
systems and actors across national and organizational borders. This paper is
focusing on the requirements and the concept of a service-oriented architecture
for publishing and finding services inside the system with intelligent
information distribution based on geographical and organizational conditions.
