Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International 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 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, Part 1. In particular the different approval criteria needed for 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. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

ISO 17423:2018(E)
Introduction
Abstracting applications from communications is a useful basic architectural principle of Intelligent
1)
Transport Systems (ITS) embodied in the ITS station and communication architecture presented in
ISO 21217:2014.
Applications and communications are linked together using the concepts of flows and paths and
communication profiles described in ISO 21217:2014 with related flow and path management
2)
[11]
procedures specified in ISO 24102-6 . 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 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
[11]
requirements is referred to as a Flow Type in ISO 24102-6 . There may be well-known registered
Flow Types as specified in ISO 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 communication profile includes the address of the next hop recipient, and a path includes address
[11]
information of the next hop recipient, the anchor and the destination as specified in ISO 24102-6 .
A user of an ITS station unit may be able to influence the selection of ITS-S communication profiles by
providing his own policies.
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
indispensable.
1) The term “Cooperative ITS” (C-ITS) indicates specific features of ITS [4]. For the purpose of this document, no
distinction between ITS and C-ITS is needed.
2) To be published.

5 Communication service parameters
5.1 Abstraction of application processes from communications
The ITS station (ITS-S) reference architecture presented in Figure 2 and specified in ISO 21217:2014
distinguishes two main blocks, i.e. "Applications" and "Communications". ITS-S application processes in
"Applications" access communication services in "Communications" through an API. Portability of ITS-S
application processes, which leads to the creation of ITS application process repositories as described
in ISO 17419, is enabled by
— abstraction of ITS-S application processes (e.g. in "Applications") from communication protocols
(in "Facilities", "Networking & Transport", "Access") and supporting management and security
functionality (in "Management", "Security") introduced as an essential basics of an ITS station in
ISO 21217:2014,
— procedures by which instances of ITS-S application processes running in an ITS station unit (ITS-SU)
specified in ISO 21217:2014 can present
