Electronic fee collection — Application interface definition for dedicated short-range communication

This document specifies the application interface in the context of electronic fee collection (EFC) systems using dedicated short-range communication (DSRC).

The EFC application interface is the EFC application process interface to the DSRC application layer, as can be seen in Figure 1. This document comprises specifications of:

— EFC attributes (i.e. EFC application information) that can also be used for other applications and/or interfaces;

— the addressing procedures of EFC attributes and (hardware) components (e.g. integrated circuit(s) card);

— EFC application functions, i.e. further qualification of actions by definitions of the concerned services, assignment of associated ActionType values, and content and meaning of action parameters;

— the EFC transaction model, which defines the common elements and steps of any EFC transaction;

— the behaviour of the interface so as to ensure interoperability on an EFC-DSRC application interface level.

This is an interface standard, adhering to the open systems interconnection (OSI) philosophy (see ISO/IEC 7498-1), and it is as such not primarily concerned with the implementation choices to be realized at either side of the interfa
