15、N.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by May 2004, and conflicting national standards shall be withdrawn at the latest byMay 2004.This document supersedes ENV 12834:1997.The development of
16、 this European Standard was carried out under European Commission Mandate M/018.This European Standard forms part of a series of European Standards defining the framework of a DedicatedShort-Range Communication (DSRC) link in the Road Transport and Traffic Telematics (RTTT) environment.The communica
17、tion requirements of many RTTT applications can be fulfilled by DSRC. The DSRC standardsenable compliant communication systems to serve multiple RTTT applications in parallel.The small service areas and severe real-time constraints require a specific protocol architecture leading to thereduced proto
18、col stack shown in Figure A, built up by the Application Layer, the Data Link Layer, and the PhysicalLayer. Such an architecture is very common for real-time environments.This European Standard gives the architecture and services offered by the DSRC Application Layer.Figure A DSRC protocol stackThe
19、following set of European Standards for the DSRC link is issued by CEN: EN 12253 “DSRC Physical Layer using Microwave at 5,8 GHz”; EN 12795 “DSRC Data Link Layer: MAC and LLC”; EN 12834 “DSRC Application Layer“ (this European Standard); prEN 13372 “DSRC Profiles for RTTT Applications“.Annexes A and
20、B are normative. Annexes C and D are informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Icela

22、mmunication tools for applicationsbased on DSRC. These tools consist of Kernels that can be used by application processes via service primitives.The application processes, including application data and application specific functions, are outside the scope ofthis European Standard.The standard is na
23、med “Application Layer” although it does not cover all functionality of OSI Layer 7 and it includes functionality from lower layers.This European Standard uses services provided by DSRC Data Link Layer, EN 12795, and covers functionality ofintermediate layers of the OSI Basic Reference Model EN ISO/
24、IEC 7498-1.Figure 1 illustrates the global data flow between the parts of the DSRC stack (Physical, Data Link and ApplicationLayers) and the application.Figure 1 Architecture and data flow of the DSRC stackNOTE For definitions of the terms used in Figure 1 see EN ISO/IEC 7498-1.B55EB1B3E14C22109E918

26、n and Chaining procedures; common encoding rules to translate data from abstract syntax ASN.1, ISO/IEC 8824-1, into transfer syntax,ISO/IEC 8825-2, and vice versa; communication initialisation and release procedures; broadcast service support; DSRC management support including communication profile
27、handling.It is outside the scope of this European Standard to define a security policy. Some transport mechanisms forsecurity related data are provided.NOTE During the lifetime of ENV 12834:1997, no implementation of the Broadcast Pool functionality has become known.Broadcast Pool functionality is t
28、herefore considered untested and is kept in this European Standard for compatibility with theENV only.B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03 EN 12834:2003 (E)62 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other
