Traffic and Travel Information (TTI) - TTI messages via cellular networks - Part 8: GSM-specific parameters

This CEN/TS defines the specific interfaces and functionality of traffic telematics (TT) services based on the use of cellular networks. Device manufacturers are enabled to develop terminal equipment compatible to services based on this CEN/TS. This will allow for interoperability of different terminal equipment and service providers which allows competition between service providers and terminal manufacturers. Furthermore it sets the scene for international availability of these services.
This CEN/TS specifies
-   TT-specific interfaces between terminal and service centre. This especially incorporates the message sets of the application data protocols and the service-independent communication handling (including conditional access and transport protocols).
-   Functionality, procedures and requirements of basic terminal components as well as their interaction with the service centre. This especially comprises conditional access and security mechanisms.
-   Service Specifications, which are essential to ensure consistent behaviour of terminal and service centre.
The services incorporated within this issue comprise:
-   breakdown and emergency services
-   interactive traffic information services
-   broadcast traffic information services
-   navigation services (route assistance, route advice, homing)
-   operator services
-   general information services
-   floating car data collection
It is envisaged that future research and development will lead to improvements on the services listed above as well as to the creation of new services. Nevertheless this CEN/TS provides the framework for seamless integration of new features and services into the existing architecture.

This Technical Specification (CEN/TS) was approved by CEN on 10 May 2001 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. 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, Czech Republic, Denmark, Finland, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United
Kingdom.

Foreword
This document (CEN/TS 14821-8:2003) has been prepared by Technical Committee CEN/TC 278 " Road
transport and traffic telematics “ and the secretariat of which is held by NEN, in collaboration with Technical
Committee ISO/TC 204 " Transport information and control systems ".
This CEN/TS was prepared by Working Group 7 of CEN TC278. In the field of Traffic and Traveller
Information, the innovative rate is high, with many research and development projects under way in many
countries, and there is a need to establish prospective standards which allow manufacturers to introduce
competitive products to the market in the knowledge that they can accommodate the future issues of the
standard(s) without fundamental change to equipment.
No known national technical specifications (identical or conflicting) exist on this subject.
CEN/TS 14821 consists of eight parts; one part describing the framework and seven parts providing detailed
specifications of all components, protocols and services that are within the scope of CEN/TS 14821.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this CEN Technical Specification: Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta,
Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

CEN/TS 14821-8:2003
Introduction
Traffic and Traveller Information (TTI) may be disseminated through a number of services or means of
communication, covering static displays, portable terminals and in-vehicle equipment.
For all such services, the data to be disseminated, and the message structure involved in the various
interfaces, require clear definition and standards formats in order to allow competitive products to operate
with any received data.
This CEN/TS focuses on an application data specification whereby data is produced at a central location and
is disseminated via a cellular radio network. It addresses the data specifications for both downlink and uplink
existing between a central location and randomly located vehicles. It enables messages to be exchanged
between different systems and service providers adopting a variety of applications specifications.
Other technical specifications are being produced by the CEN TC278 Working Group 4 to cover TTI
dissemination via other means or services. This set of specifications is named GATS (Global Automotive
Telematics Standard). GATS provides the modular framework for implementing such traffic telematics
services on an open technology platform and is network - independent. In many details definitions are
necessary to ensure interoperability. Therefore, in this network specific part of the standard those detailed
definitions are given. With the development of future mobile communication systems towards UMTS /
IMT2000 the bottleneck of narrow-band data communication might fade. Due to its modular structure, the
GATS framework and applications are prepared for that due to its network-independence. The same holds
for emerging technologies for positioning which today is almost exclusively based on GPS.
Other relevant standard developments are, independent from telematics, the application-independent
Wireless Application Protocol (WAP), enabling mobile access to the Internet. It is understood that these
emerging technologies might fit into the framework of telematics applications in future WAP-versions. For the
time being, GATS already today independently from WAP enables access to telematics services. Utilisation
of GATS on a WAP protocol stack and identifying necessary adaptation of WAP specifications (if any) is
currently under investigation of the appropriate groups within WAP-Forum and GATS-Forum.
