This International Standard specifies the application layer core which provides communication tools forapplications based on DSRC. These tools consist of kernels that can be used by application processes viaservice primitives. The application processes, including application data and application-specific functions, areoutside the scope of this International Standard.This International Standard is named “application layer”, although it does not cover all functionality of OSILayer 7 and it includes functionality from lower layers.It uses services provided by DSRC data link layer, and covers functionality of intermediate layers of the “OSIBasic Reference Model” (ISO/IEC 7498-1).The following subjects are covered by this International 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 transfersyntax (ISO/IEC 8825-2:2002) and vice versa;-- communication initialisation and release procedures;-- broadcast service support;-- DSRC management support including communication profile handling; and-- extensibility for different lower layer services and application interfaces.It is outside the scope of this International Standard to define a security policy. Some transport mechanismsfor security-related data are provided.
