Intelligent Transport Systems (ITS); Framework for Public Mobile Networks in Cooperative ITS (C-ITS)

The scope of the work item is to (a) analyse cooperative ITS services using public mobile cellular networks for communications between ITS stations in order to identify related functional requirements on the ITS architecture, (b) identify required amendments / modifications of existing standards on cooperative ITS in order to enable usage of public mobile cellular networks, (c) identify functionality to be specified in new ITS standards to be developed under M/453. The result is to be presented as an ETSI Technical Report. Starting from the architecture described in the published standard 'ITS Communication Architecture' EN 302 665 v1.1.1, and considering primarily the 'Basic Set of Applications' defined in ETSI TR 102 638, a critical assessment of the applicability of the 3G - 4G mobile network access to support the described application scenarios will be provided. This analysis aims to refer to technical standards developed by 3GPP and ETSI TC M2M as much as possible. This analysis is based on the ITS station architecture and also covers security aspects. Additional technical background provided by R&D projects such as CoCAR (http://www.aktiv-online.org/english/aktiv-cocar.html), CoCARx (the follow-on project including integration between LTE and DSRC access technologies), and CVIS (http://www.cvisproject.org/) is intended to be considered for the development of the Technical Report. Related standards from other SDOs working on cooperative ITS also will be considered as appropriate. This approach is coherent with the spirit of the 'Joint CEN and ETSI Response to Mandate M/453', with specific reference to clause 3.3. 'Standardisation for Co-operative systems covering other media' and clause 4.2.3. 'National R&D projects including national FOTs'.
