pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.

right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does
not constitute an endorsement by ETSI of products, services or organizations associated with those trademarks.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport Systems
(ITS).
The present document includes the integration of infrastructure based application protocols within the ITS message
environment.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The infrastructure services are application support facilities provided by the Facilities layer that construct, manage and
process messages distributed from infrastructure to end-users or vice-versa based on payload received from the
application. The infrastructure services specified in the present document support infrastructure-based applications in
order to achieve communication interoperability, and may be implemented in parallel to other services in an ITS-S.

1 Scope
The present document provides specifications of infrastructure related ITS services to support communication between
infrastructure ITS equipment and traffic participants using ITS equipment (e.g. vehicles, pedestrians). It defines services
in the Facilities layer for communication between the infrastructure and traffic participants. The specifications cover the
protocol handling for infrastructure-related messages as well as requirements to lower layer protocols and to the
security entity.
