Clause 5 collects and analyses the relevant V2X use cases (including the findings from external organizations). The recommendations on the se

34、rvices and features are identified for each use case. Evaluation is provided for each recommendation to identify the issues to be solved. Clause 6 discusses the key issues and the corresponding solutions and further identifies the gaps from the existing MEC functions and features. Clause 7 concludes

35、 the study with the prioritized V2X use cases to be supported in this phase, and the consolidated recommendations. The recommendations for necessary normative work are provided in order to close the identified gaps. 5 Use cases 5.1 Introduction This clause discusses four use case groups that are com

36、monly known to the V2X communities i.7, namely “safety“, “convenience“, “advanced driving assistance“ and “vulnerable road user“. ETSI ETSI GR MEC 022 V2.1.1 (2018-09) 7 5.2 V2X use case group “safety“ 5.2.1 Description The V2X use case group “Safety“ includes several different types of use cases (r

37、elevant to MEC) to support road safety using the vehicle-to-infrastructure (V2I) communication in addition to the vehicle-to-vehicle (V2V). Intersection Movement Assist (IMA) This type of use cases was specifically listed in the US DOT NHTSA publication 2016-0126 i.1, and ETSI TR 102 638 i.2. The ma

38、in purpose of IMA is to warn drivers of vehicles approaching from a lateral direction at an intersection. IMA is designed to avoid intersection crossing crashes, the most severe crashes based on the fatality counts. Intersection crashes include intersection, intersection-related, driveway/alley, and

39、 driveway access related crashes. Figure 5.2.1-1 illustrates two typical scenarios: a) intersection collision warning, and b) intersection management. a) intersection collision warning b) intersection management Figure 5.2.1-1: V2X “safety“ use cases Queue Warning (QW) i.3 In a lot of situations, a

40、queue of vehicles on the road may pose a potential danger and cause delay of traffic, e.g. when a turning queue extends to other lanes. Using the V2I service, the queue information can be made available to other drivers beforehand. This minimizes the likelihood of crashes and allows for mitigation a

41、ctions. 5.2.2 Recommendations This group of V2X use cases requires the support of roadside infrastructure for the V2V and V2I communications. In the case that the Multi-access Edge Computing system is used to provide the V2X support, the related recommendations on the services and features enabled i

42、n the system include: R-5.2.2-1 It is recommended that the MEC system provides feedback information from the network to the vehicle in support of V2X functions, predicting whether a communication channel is currently reliable or not (e.g. in terms of fulfilling latency requirements and 100 % packet

43、arrival). R-5.2.2-2 It is recommended that the MEC system provides interoperability by supporting V2X information exchange among road users connected through different access technologies or networks or mobile operators. R-5.2.2-3 It is recommended that the MEC system enables multi-operator operatio

44、n for V2X mobiles/users to provide service continuity across access network coverage nationwide and across borders of different operators networks. R-5.2.2-4 It is recommended that the MEC systems provide interoperability in a multi-operator scenario, enabling MEC apps in different systems to commun

45、icate securely with each other, in order to enable synchronization in multi-operator systems also in absence of cellular coverage (outside of 3GPPTMdomain). ETSI ETSI GR MEC 022 V2.1.1 (2018-09) 8 R-5.2.2-5 It is recommended that the MEC system provides interoperability in a multi-operator scenario,

46、 enabling MEC apps to communicate securely with the V2X-related 3GPPTMcore network logical functions (e.g. V2X control function) and gathering PC5 i.10 V2X relevant information (e.g. PC5 configuration parameters) from 3GPPTMnetwork. 5.2.3 Evaluation R-5.2.2-1 In current MEC system, the RNI API can p

47、rovide up-to-date radio network information to the service consumer, i.e. the V2X functions. However, current QoS-related information in RNI API is not sufficient in order to allow necessary prediction regarding the QoS performance (e.g. latency, throughput, reliability). Therefore, potential enhanc

48、ements on RNI API for the prediction should be considered including both relevant measurements in RAN or processed results for the prediction. This enhanced service could also be provided by a new API. R-5.2.2-2 In current MEC definition, MEC system includes not only 3GPPTMaccess, but also other non

49、-3GPPTMaccess. Therefore the MEC system is RAT agnostic and will be enhanced for multi-access if needed. There is no need to consider the different access networks within an operators system in this study. Moreover, the information exchange among MEC system from different operators may require potential enhancement on the horizontal communication for the MEC system. R-5.2.2-3 The operator network is normally region specific or country specific. The V2X service requires a seamless coverage of the commu
