ITU-T F.749.2 (03/2017) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs
9、). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication S
10、tandardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of informa
11、tion technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency
12、. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some o
13、ther obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or impl
14、ementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development proces
15、s. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly

Some use cases are
22、 included in Appendix I. 2 References None. 3 Definitions 3.1 Terms defined elsewhere This Recommendation uses the following terms defined elsewhere: 3.1.1 functional entity b-ITU-T Y.2012: An entity that comprises an indivisible set of specific functions. Functional entities are logical concepts, w
23、hile groupings of functional entities are used to describe practical, physical implementations. 3.1.2 intelligent transport systems (ITS) b-ITU-R M.1797: ITS can be defined as systems utilizing the combination of computers, communications, positioning and automation technologies to improve the safet
24、y, management and efficiency of terrestrial transport systems. 3.1.3 nomadic devices b-ITU-T F.749.1: Nomadic devices include all types of information and communication as well as entertainment devices that can be brought into the vehicle by the driver and/or passengers to be used while driving. Exa
25、mples include mobile phones, portable computers, tablets, mobile navigation devices, portable media players and multi-functional smart phones. 3.1.4 telematics b-ISO 15638-1: Telematics is the use of wireless media to obtain and transmit (data) from a distant source. 3.1.5 vehicle gateway (VG) b-ITU
26、-T F.749.1: A VG is a device in a vehicle that enables communications between a device in the vehicle and another device which may be physically located either inside the vehicle or outside the vehicle (e.g., roadside station, cloud-based server, etc.). A VG provides standardized interfaces and prot
27、ocols, communications across heterogeneous networks, optimized network selection based on application needs and network QoS, arbitration and integration of network communications, security and switching network connections to maintain service continuity. 3.1.6 vehicle gateway platform (VGP) b-ITU-T
28、F.749.1: A VGP is the collection of ICT hardware and software in a vehicle operating as an open platform to provide an integrated runtime environment for delivering the communications services of a VG. A VGP may also provide higher layer communications services such as interaction with the driver th
29、rough the driver-vehicle access services and so on. Subsystems dedicated solely to vehicle operation are not considered part of the VGP. Supported applications/services include ITS and infotainment. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 drive
30、r-vehicle interface (DVI): The integrated user interface for the vehicle. It includes visual displays, loudspeakers, microphones, manual input controls, etc. 2 Rec. ITU-T F.749.2 (03/2017) 3.2.2 remote user interface: An approach to realize the interaction between applications in nomadic devices and
31、 the driver-vehicle interface (DVI). The UI of applications in nomadic devices can be displayed in the vehicles touch screen, and drivers are able to control the applications through the DVIs (touch screen, buttons, etc.). A remote UI can help drivers avoid distraction from applications and thus red
32、uce the probability of accidents. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: 2G Second generation of cellular phone technologies 3G Third generation of cellular phone technologies 4G Fourth generation of cellular phone technologies API Application

ITU-T F.749.2 (03/2017) 3 5 Conventions In this Recommendation: The keyword “shall“ indicates a
36、requirement which must be strictly followed and from which no deviation is permitted if conformance to this document is to be claimed. The keywords “should“ and “optional“ indicate an optional requirement which is permissible. This term is not intended to imply that the vendors implementation must p
37、rovide the option, and the feature can be optionally enabled by the vendor. Rather, it means the vendor may optionally provide the feature and still claim conformance with the specification. 6 Descriptions and characteristics of VGP 6.1 Descriptions Figure 1 shows the VGP positioning in the intellig

39、ture scenario mainly includes safety, electronic toll collection (ETC) and traffic information exchange use cases in which vehicles communicate with roadside infrastructures. 3) Vehicle-to-cloud-based server The vehicle-to-cloud-based server scenario set mainly includes emergency call and some telem
40、atics scenarios in which vehicles communicate with cloud-based servers. 4) Vehicle-to-nomadic device The vehicle-to-nomadic device scenario set mainly includes telecommunication and remote user interface (UI) use cases in which vehicles connect to nomadic devices. 5) Vehicle-to-pedestrian and bicycl
41、e The vehicle-to-pedestrian and bicycle scenario set mainly includes safety warning use cases in which vehicles communicate with devices carried by pedestrians and bicycles. 6) Interaction with in-vehicle network The interaction with in-vehicle network scenario set mainly includes vehicle diagnostic
42、s, remote data collection and vehicle remote control use cases in which the VGP communicates with the in-vehicle networks. 4 Rec.
