标准摘要
[中文适用范围]： 本国际标准规定了智能运输系统（ITS）中陆地移动通信访问（CALM）相关国际标准系列的架构通信框架。该架构以抽象方式描述，包含多种图形视图和示例。图形表示部分遵循国际标准化组织（ISO）开放系统互连（OSI）原则。除了本国际标准中规定的要求外，还提供了若干注释和示例来说明CALM概念。在可行的情况下，本国际标准通过参考并选择适用的现有国际标准制定。该架构提供了区域变通方案，以适应不同国家和地区法规的差异。 [外文原描述]： ISO 13183:2012 specifies the architectural communications framework of intelligent transport systems (ITS) for the family of communications access for land mobiles (CALM) related International Standards. The architecture is described in an abstract way with several graphical views and examples. The graphical representations partly follow the ISO open systems interconnection (OSI) principles. In addition to the requirements specified within ISO 13183:2012, a number of notes and examples are provided to illustrate the CALM concept.
