DESCRIPTION

EN 12834


EN 12834 Road transport and traffic telematics - Dedicated Short Range Communication (DSRC) - DSRC application layer - This European Standard specifies the Application Layer Core which provides communication tools for applications based 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 of this European Standard. The standard is named '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 of intermediate layers of the OSI Basic Reference Model [EN ISO/IEC 7498-1]. Figure 1 illustrates the global data flow between the parts of the DSRC stack (Physical, Data Link and Application Layers) and the application. The following subjects are covered by this European Standard: - application Layer structure and framework; - services to enable data transfer and remote operations; - application multiplexing procedure; - fragmentation procedure; - concatenation 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 handling. It is outside the scope of this European Standard to define a security policy. Some transport mechanisms for security 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 therefore considered untested and is kept in this European Standard for compatibility with the ENV only.
