This Technical Specification (CEN/TS) was approved by CEN on 30 October 2022 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
United Kingdom.

European foreword
This document (CEN/TS 17184:2022) has been prepared by Technical Committee CEN/TC 278
“Intelligent transport systems”, the secretariat of which is held by NEN.
This document supersedes CEN/TS 17184:2018.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
Part of this revision of the document is aimed at making it purely packet switched and removing
references to eCall over circuit switched networks, this in order to make the document future proof.
In comparison with the previous edition, the following technical modifications have been made:
— reordering and combining of some clauses to better reflect coherence and provide consistency
(numbering below refers to the current numbering; where this differs from the numbering in the
previous published version of this document, the original number is cited stroke through and
between brackets)
— provide a mechanism to transfer the MSD via in-band modem via IMS as an option (Clause 7.8 (7.3.6
and 7.4.3))
— added expected IVS behaviour after reception of 6xx or 4xx response including positive MSD A
