ISO 14816:2005建立了RTTT/ITS系统中明确标识的通用框架数据结构。它不包括任何物理方面,如接口。它既不是特定于频率,也不是特定于空中接口协议。
因此,不包括构成传输或存储协议一部分的数据元素,如报头、帧标记和校验和。
ISO 14816:2005中未包含数据结构元素的变更保护、分类和鉴定安全方面的规范。
根据ISO/TC 204和CEN/TC 278的指南,采用了ISO/IEC 8824、ISO/IEC 8825-1和ISO/IEC 8825-2中确定的数据元素结构和描述原则,以在标准框架内提供可互操作的体系结构。
ISO 14816:2005定义了基于ISO/IEC 8824-1 ASN的数据结构。1通用类类型,可以直接导入到只需要完整应用程序类类型子集的其他应用程序标准。这些通用类和应用程序类类型被唯一定义为ASN。1附录B中的模块。该模块可直接链接到应用程序数据定义中。
ISO 14816:2005定义了不存在其他相关应用标准的简单AVI/AEI应用的默认编码。该定义构成第4条。
ISO 14816:2005 establishes a common framework data structure for unambiguous identification in RTTT/ITS systems. It excludes any physical aspects such as interfaces. It is neither frequency- nor air interface protocol-specific.
Data elements that form part of transmission or storage protocols such as headers, frame markers and checksums are thus excluded.
The specifications for protecting against changes, classifying and qualifying security aspects of the data structure elements are not included within ISO 14816:2005.
The principles of data element structure and description determined in ISO/IEC 8824, ISO/IEC 8825-1 and ISO/IEC 8825-2 have been adopted to provide an interoperable architecture within a standard framework according to guidelines from ISO/TC 204 and CEN/TC 278.
ISO 14816:2005 defines data structures based on the ISO/IEC 8824-1 ASN.1 UNIVERSAL CLASS types that may be directly IMPORTED to other application standards that would need only subsets of the full APPLICATION CLASS types. These UNIVERSAL CLASS and APPLICATION CLASS types are uniquely defined as an ASN.1 module in Annex B. This module may be directly linked into an application data definition.
ISO 14816:2005 defines default encoding for simple AVI/AEI applications where no other relevant application standard exists. This definition forms Clause 4.
