Foreword This Technical
22、 Report (TR) has been produced by ETSI Technical Committee Intelligent Transport System (ITS). In the present competitive environment, however, the risk of non-interoperability is increasing because of small windows of opportunity due to fast evolution of technology, or the use of non-open standards
23、. But in large, complex systems such as those envisioned by ITS this is not workable in the long run. It can be argued that interoperability is one of the main aims of ETSI standardization. Key components in the ETSI approach to interoperability are the delivery of high quality interoperable standar
24、ds, the availability of standardized test specifications and the practical provision of interoperability events. With this in mind, experts from ETSI have contributed to the development and review of this present document (C2C-CC Demonstrator 2008). While the primary intention is that these demonstr
25、ation scenarios are used in the Car 2 Car Forum and Demonstration 2008 it is hoped that the work will continue beyond that, i.e. the results will be valued input to standardization in this domain It is strongly believed that the availability of a complete set of well-defined standardized interoperab
26、ility scenarios and associated specifications is an important factor in the delivery of truly interoperable car-to-car products and systems. Introduction The Car 2 Car Communication Consortium is actively driving harmonization, standardization, and market introduction of V2X systems. It is leveragin
27、g research results, incubating them towards maturity, and consolidating them for standardization since successfully standardized and harmonized systems are very attractive from an economic point of view, hence having best chances to get deployed on the mass market. Having said this it is essential t
28、o actively promote the harmonization of technologies and to enforce the adoption and validation of these. Furthermore, it is required to demonstrate the viability of such technologies. The C2C-CC Demonstration 2008 intended to illustrate to the public that European vehicle manufacturers and supplier
29、s jointly work on the elaboration of globally harmonized standards. The main objectives were to show interoperable applications across the different vehicle manufacturers and interoperable communications units from different suppliers working seamlessly together. As a result of the C2C-CC Demonstrat
30、ion 2008, interoperability between the applications of nine vehicle manufacturers based on different communications equipment provided by five suppliers has been successfully demonstrated. Although the demonstrations did not include a complete set of functionalities required for a final system, it w
31、as shown for the first time that interoperability was not limited to the application level only but included all communications layers. Therefore, the technical specifications used for the C2C-CC Demonstration 2008 as well as the corresponding results thereof are considered valuable input for future
32、 ITS related standardization work. The present document is a consolidated review of the C2C-CC Demonstration 2008 to which participants such as Alpine, Audi, BMW, Daimler, Delphi, Denso, DLR, ETSI Centre for Testing and Interoperability, Fraunhofer FOKUS, Fiat, Hitachi, Honda, NEC, Opel, Renault, Re
33、nesas, Siemens Austria, University of Applied Sciences Saarland (HTW), Volvo and VW actively contributed. The intention of the present document is to serve as basis for future standardization work. ETSI ETSI TR 102 698 V1.1.2 (2010-07) 61 Scope The present document provides: a detailed description o
34、f Use Cases demonstrated during the C2C-CC Forum and Demonstration event 2008; a report on the corresponding technical specifications of the demonstrator system covering all communication layers. It is understood that the C2C-CC demonstrator 2008 did not implement the complete functionality of a fin
35、al system. However the implementations have been specified with a high demand with respect to interoperability and the current standardization status Therefore, it is intended that this report contributes to future standardization work: with a basic description of selected use cases; with a definiti
36、on of a basic set of Application Support Facilities (CAM/DNM), which enable the selected use cases; with the specification of basic settings of the underlying communication layers (PHY-TRA) including communication security. Moreover, the present document gives an example on how to visualize basic te
37、chnological mechanisms such as Application Support Facilities (ASF), which are usually hidden to an end-user. This is can be of great value for future public demonstrations and interoperability tests. 2 References References are either specific (identified by date of publication and/or edition numbe

44、Harmonized EN covering the essential requirements of article 3.2 of the R particularly in case a cheap system is desirable, which is also affordable for low-class vehicles. Therefore, future processes for the specification of data modelling and communication security should consider the system resou
45、rces, which are related to the proposed solutions. ETSI ETSI TR 102 698 V1.1.2 (2010-07) 138 Final Remarks This clause aims to help to obtain a very basic overview about important functionalities, which were not implemented for the C2C-CC Demonstrator 2008, but which are considered as indispensable
46、for the proper operation of a final system. Many of these functionalities will most probably be presented in future V2X demonstrations. In this context it is worth mentioning that the efforts required for the visualization of technological functionalities will drastically increase, which will finall
47、y be an aspect to be considered for future demonstrations. However this does not influence the necessity of these functions for the real system. Use Cases based on Decentralized Environmental Notification Messages have complex requirements with respect to the applied strategy for message disseminati
48、on. On one hand the network may not get congested in dense traffic scenarios. This should be tackled by underlying routing and multi-hop forwarding mechanisms of the network layer and related congestion control measures. Transmit Power Control mechanisms are also aiming to reduce the load in dense n
49、etwork scenarios. On the other hand, a critical safety message should not get lost in sparse network scenarios, e.g. a rural road at night. Therefore, it is essential that DNMs are stored and “physically“ transported in the relevant area (dissemination area) for the time of their validity. This is even truer for the market introduction phase where only a small amount of vehicles will be equipped with V2X communication devices. Following a reasonable coexistence of store and forward (“physical transport of queued messages“) and multi-hop routing mechan
