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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 204, Intelligent transport systems.
ISO 17515 consists of the following parts, under the general title Intelligent transport systems —
Communications access for land mobiles (CALM) — Evolved Universal Terrestrial Radio Access Network
(E-UTRAN):
— Part 1: General usage
Additional parts, dealing with direct communications and routing functionalities, are under preparation.

ISO 17515-1:2015(E)

Introduction
This International Standard is a member of the set of International Standards developed under the
acronym “Communications Access for Land Mobiles” (CALM) that refers to ISO/TC 204 work items. An
introduction to this set of International Standards is provided in ISO 21217.
This part of ISO 17515 is part 1 of a multipart standard which determines usage of technology developed
under the acronym E-UTRAN for usage as a communication interface in an ITS station unit.
The term long-term evolution (LTE) is commonly used to refer to the set of standards containing the
E-UTRAN technical specifications. In this part of ISO 17515, the term “E-UTRAN” is used to refer to
these specifications and can be treated as a synonym for “LTE”.

INTERNATIONAL STANDARD ISO 17515-1:2015(E)
Intelligent transport systems — Communications access
for land mobiles (CALM) — Evolved Universal Terrestrial
Radio Access Network (E-UTRAN) —
Part 1:
General usage
1 Scope
This part of ISO 17515 enables usage of the E-UTRAN cellular network technology as an ITS access
technology in an ITS station by specifying details of the “Communication Adaptation Layer” (CAL) and
the “Management Adaptation Entity” (MAE) of communication interfaces specified in ISO 21218, and
session management by reference to ISO 25111.
Wherever practicable, this part of ISO 17515 has been developed by reference to suitable extant
standards, adopted by selection.
