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.

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

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”.

6 Communication and management adaptation
6.1 Communication interface
The concept of a communication interface (CI) is introduced in ISO 21217 as part of the ITS station
reference architecture. Interfaces, management, behaviour, and parameters of CIs are specified in
ISO 21218, especially the adaptation of a CI access technology
— to the communication service access point IN-SAP, and
— to the management service access point MI-SAP, with reference to ISO 24102-3.
Such adaptation enables a common definition of IN-SAP and MI-SAP service primitives for all kinds
of access technologies. Details of this adaptation functionality dedicated to the access technology
E-UTRAN are specified in 6.2 and 6.3.
6.2 Communication adaptation
6.2.1 Communication adaptation layer
The “Communication Adaptation Layer” (CAL) specified in ISO 21218 provides the IN-SAP towards the
ITS-S networking and transport layer.
An E-UTRAN implementation according to this International Standard shall support UC-VCIs and
the related procedures specified in ISO 21218. The Link-ID shall be constructed as specified in
ISO 21218:2013, 6.3 and C.3.
6.3 Management adaptation
6.3.1 Management adaptation entity
The “Management Adaptation Entity” (MAE) specified in ISO 21218 provides the MI-SAP towards the
ITS-S management entity described in ISO 21217. The MI-SAP services, service primitives and service
primitive functions are specified in ISO 24102-3.
The MI-COMMANDs presented in Table 1 shall be supported:
