This Technical Specification 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.
