The development of mobile phone technology, from the introduction of the first cellular systems in the mid-eighties, caused a rupture in the telecommunications industry service model. To fill the gaps created by the technological breakthrough in the service availability architecture, which arose in the transition from first generation (analog) to the second (digital), the 3GPP (Third Generation Partnership Project) has developed a model that resulted in an architecture called IMS - IP Multimedia Subsystem. The IMS architecture was initially developed in order to meet the needs of 3GPP in the context of cellular systems and became the basis of the session control architecture for third generation networks (3G) and their evolution (4G networks), where the focus is no longer the increase in capacity or bandwidth, but the interoperability between heterogeneous access networks, such as HSPA - High Speed Packet Access, LTE - Long Term Evolution, WiMAX - Worldwide Interoperability for Microwave Access, Wi-Fi - Wireless Fidelity, DSL - Digital Subscriber Line, DOCSIS - Data over Cable Service Interface Specifications and others. Based on the premise that increasing Intelligent Transportation Systems (ITS) services will be available on mobile devices (embedded or portable), the proposed architecture of 3GPP (IMS) can be extended to cover the ITS applications. The IMS can be used to implement the ITS sub architectures because it has the ability to provide multiple ITS services on the same session, regardless the different types of mobile devices used to access these services.
