The work of preparing Interna
21、tional Standards is normally carried out through ISO technical committees. 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
22、ISO, also take part in the work. ISO collaborates closely with the 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, P
23、art 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

28、itectural principle of Intelligent Transport Systems 1)(ITS) embodied in the ITS station and communication architecture presented in ISO 21217.Applications and communications are linked together using the concepts of flows and paths and communication profiles described in ISO 21217 with related flow
29、 and path management procedures specified in Reference 6. The ITS station management uses communication requirements and objectives of applications together with the capabilities of the ITS station (status of available communication protocol stacks) and sets of decision rules (regulations and polici
30、es) to select suitable parameterized ITS-S communication protocol stacks, also referred to as “ITS-S Communication Profiles” (ITS-SCP), for each source of a potential flow as illustrated in Figure 1. A set of communication requirements is referred to as a Flow Type in Reference 6. There may be well-
31、known registered Flow Types as specified in ISO/TS 17419.Figure 1 ITS-S communication profile selection processAn ITS-S communication profile is independent of any destination address. However an instantiation of a communication profile includes the address of the next hop recipient, and a path incl
32、udes address information of the next hop recipient, the anchor and the destination as specified in Reference 6.A user of an ITS station unit may be able to influence the selection of ITS-S communication profiles by providing his own policies.1) The term “Cooperative ITS” (C-ITS) indicates specific f
33、eatures of ITS1. For the purpose of this Technical Specification, no distinction between ITS and C-ITS is needed.
