The work of preparing International Standards is normally carried out through ISO technical c
24、ommittees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with t
25、he International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
26、the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

30、All rights reserved vBS EN ISO 17423:2018ISO 17423:2018IntroductionAbstracting applications from communications is a useful basic architectural principle of Intelligent Transport Systems1)(ITS) embodied in the ITS station and communication architecture presented in ISO 21217:2014.Applications and co
31、mmunications are linked together using the concepts of flows and paths and communication profiles described in ISO 21217:2014 with related flow and path management procedures specified in ISO 24102-62)11. The ITS station management uses communication requirements and objectives of applications toget
32、her with the capabilities of the ITS station (status of available communication protocol stacks) and sets of decision rules (regulations and policies) to select suitable parameterized ITS-S communication protocol stacks, also referred to as “ITS-S Communication Profiles“ (ITS-SCP), for each source o
33、f a potential flow as illustrated in Figure 1. A set of communication requirements is referred to as a Flow Type in ISO 24102-611. There may be well-known registered Flow Types as specified in ISO 17419.Figure 1 ITS-S communication profile selection processAn ITS-S communication profile is independe
34、nt of any destination address. However an instantiation of a communication profile includes the address of the next hop recipient, and a path includes address information of the next hop recipient, the anchor and the destination as specified in ISO 24102-611.A user of an ITS station unit may be able
35、 to influence the selection of ITS-S communication profiles by providing his own policies.Information from a Local Dynamic Map (LDM) on neighbouring stations offering certain communication capabilities may also be useful for the ITS-S communication profile selection process, although not indispensab
