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

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