IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
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 (http://ipr.etsi.org).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport System (ITS).
The present document is part 1 of a multi-part deliverable covering OSI cross-layer topics as identified below:
Part 1: "Architecture and addressing schemes";
Part 2: "Management information base";
Part 3: "Interface between management entity and access layer";
Part 4: "Interface between management entity and networking & transport layer";
Part 5: "Interface between management entity and facilities layer";
Part 6: "Interface between management entity and security entity";
Part 7: "Interface between security entity and access layer";
Part 8: "Interface between security entity and networking & transport layer";
Part 9: "Interface between security entity and facilities layer";
Part 10: "Interface between access layer and networking & transport layer";
Part 11: "Interface between networking & transport layer and facilities layer".
Introduction
Intelligent Transport Systems (ITS) are systems to support transportation of goods and humans with information and
communication technologies in order to efficiently and safely use the transport infrastructure and transport means (cars,
trains, planes, ships). Complementary elements of ITS are standardized in various standardisation organisations such as
ISO TC204/CEN TC278 and ETSI TC ITS.
The architecture of communications in ITS (ITSC) specified in [1] and [2] introduces the ITS station reference
architecture with the internal functional blocks:
• access layer,
• networking & transport layer,
• facilities layer,
• ITS applications,
• management entity,
ETSI
5 ETSI TS 102 723-1 V1.1.1 (2012-11)
• security entity,
and the interfaces between these blocks.
Various general addressing mechanisms, the ITS station management information base, and the details of these
interfaces specified in this multi-part deliverable complement the general architecture of ITSC.
This multi-part deliverable partly acts as input to the standards making process for the various protocols of ITSC, but
also is built from feed-back from this process.

1 Scope
The present document specifies:
• the architectural approach to interconnect the various layers and entities of the ITS station reference
architecture,
• unique addressing schemes for entities in an ITS station,
• station-local management communications,
• common terms and definitions.
