CEN/TS 14821-5:2003

Traffic and Travel Information (TTI) - TTI messages via cellular networks - Part 5: Internal services

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 technical specification. 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 technical specification 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 technical specification provides the framework for seamless integration of new features and services into the existing architecture.

networks - Part 5: Internal services
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 14821-5:2003) has been prepared by Technical Committee CEN/TC 278
"Road transport and traffic telematics", the secretariat of which is held by NEN, in collaboration with

Technical Committee ISO/TC 204 "Transport information and control systems".
This technical specification 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.
In accord
