28、n Abstracting applications from communications is a useful basic architectural 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 pat
29、hs and communication profiles described in ISO 21217 with related flow and path management procedures specif ied 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 communicat
30、ion 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 of a potential flow as illustrated in Figure 1. A set of communication requir
31、ements is referred to as a Flow Type in Reference 6. There may be well-known registered Flow Types as specified in ISO/TS 17419. Figure 1 ITS-S communication profile selection process An ITS-S communication profile is independent of any destination address. However an instantiation of a communicatio
32、n 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 Reference 6. A user of an ITS station unit may be able to influence the selection of ITS-S communication profiles by providing h
33、is own policies. 1) The term “Cooperative ITS” (C-ITS) indicates specific features of ITS 1 . For the purpose of this Technical Specification, no distinction between ITS and C-ITS is needed.
