IMS and Presence Service Integration on Intelligent Transportation Systems for Future Services

Once some stable solutions appear to be found at physical and network layers for cooperative Intelligent Transportation Systems (ITS), deploying vehicular services and managing their operation over a common framework is becoming a key issue. Apart from proprietary and ad-hoc solutions, this paper presents a platform based on the IP Multimedia Subsystem (IMS) for deploying ITS services. The proposed architecture decouples IMS from a specic communication technology, to provide a common framework where to deploy and access both peerto-peer and infrastructure-oriented ITS services. IMS capabilities have been used as an overlay network to provide vehicular services. Standard features of IMS, such as authentication, authorization, accounting, instant messaging, and session or subscription management, are exploited as a common basis for ITS services. In particular, the work presented shows how the standardized IMS Presence Service can be extremely useful for services which follow a publish-s...
