适用范围：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 terminalequipment compatible to services based on this standard. This will allow for interoperability of differentterminal equipment and service providers which allows competition between service providers andterminal 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 themessage sets of the application data protocols and the service-independent communicationhandling (including conditional access and transport protocols).· Functionality, procedures and requirements of basic terminal components as well as their interactionwith the service centre. This especially comprises conditional access and security mechanisms.· Service Specifications, which are essential to ensure consistent behaviour of terminal and servicecentre.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 collectionIt is envisaged that future research and development will lead to improvements on the services listedabove as well as to the creation of new services. Nevertheless this technical specification provides theframework for seamless integration of new features and services into the existing architecture.
