Specialist Task Force 365:
Lower Layer Service Access Points (ISO DIS 21218)
Conformance Testing in support of Interoperability
Who we are:
Team Leader: Dr.
Team Members: Dr.
Why we do it:
The work of STF 365 is made in relation to the Intelligent Transport element of
the EC’s “2008 ICT standardisation work programme” (Part II: Commission services
priorities for ICT standardisation in 2008), which identifies support to
standardisation aspects of EU legislation. The standardisation work programme,
among other things, invites the ESOs to further continue the ongoing
standardisation needs arisen from the i2010 Intelligent Car initiative including
standardisation of the testing procedures, especially in the light of the
forthcoming European Electronic Tolling System (EETS).
EETS is an important example of applications for Intelligent Transport Systems
(ITS). The ITS approach specified in ISO TC 204 WG16 CALM, of which ISO 21218 is
one of the most important kernel standards, supports EETS as it means for the
smooth introduction of GNSS/CN based tolling applications, as well as support
for DSRC radio interfaces, and in general by providing general support for ITS
applications. CALM will also provide next generations of networks, e.g. operated
at 63 GHz, providing significantly increased communications capacity. The
European Commission has acknowledged the importance of ITS CALM standardization
by funding large scale research projects with field trials.
Although this approach is efficient, it does not cover the problems of equipment
development by different manufacturers and the related problems of compatibility
and interoperability. This is why the stakeholders are interested in a confident
approach towards test standards for pan-European and preferably international
An essential preparatory work to support interoperability of ITS in Europe and
world-wide is the provision of conformance test suites. STF 365 is for
developing DTS/ITS-0020009 "Intelligent Transport Systems (ITS); Road Transport
and Traffic Telematics (RTTT); Test specifications for Intelligent Transport
Systems, Communications Access for Land Mobiles (CALM), Medium Service Access
Points (ISO 21218); Part 2: Test Suite Structure and Test Purposes (TSS & TP)".

How we do it:
work will be conducted under the supervision of and in close contact with ETSI
TC ITS WG2. The base standard ISO 21218 will be checked, together with the draft
Implementation Conformance Statement (ICS) proforma produced by ETSI TC ITS WG2,
in order to both derive Test Purposes, and to devise inconsistencies or errors
in the input documents. Proposals for modifications to the input documents will
be produced, based on that analysis, to be delivered to the appropriate
standardization bodies as a side effect of the STF’s work.
Time plan for the work:
The work has begun in January 2009. The Technical Specification will be
submitted for final approval in October 2009, allowing publication before the
end of 2009.
