Much of seminal work has been reported on the topic of intelligent transportation systems ITS in the recent years. Many advanced techniques have been garnered to improve online communication and to promote the security comfort and efficiency of ITS. Of primary importance to the effective application of ITS is the communication protocol used. A fascinating development is that the yesterday s Global System for Mobile Communication protocol is being replaced by the Universal Mobile Telecommunication System protocol which is the third-generation mobile technology. This article attempts to identify a suitable communication system for ITS applications. It is impracticable to substantially modify the original UMTS-IMS-AKA protocol which is in practice because it can disturb the operation of the current system and thus we explore other possibilities through this research. We investigate a novel protocol to make the original UMTS-IMS-AKA protocol compliant with ITS as well as adaptable into the current UMTS protocol. Copyright 2009 Hsia-Hung Ou et al.
