标准摘要
[中文适用范围]： 本文档描述了两个或多个 ITS 站点通过全球互联网通信网络进行通信时所使用的 CoAP 功能。假设读者熟悉本文档中使用的各个 CoAP 和 6LoWPAN 协议块的征求意见稿 (RFC) 中的 IETF 规范。本文档并未定义新的协议、CoAP 层的新消息交换或新的数据结构。它定义了如何组合 IETF 标准化的协议，以便 ITS 站点能够使用 CoAP 相互通信。 [外文原描述]： ISO 19080:2016 describes the CoAP facilities between two or more ITS stations communicating over the global internet communication network. It is assumed that the reader is familiar with IETF specifications found in request for comments (RFCs) of individual CoAP and 6LoWPAN protocol blocks used within this document. This document does not define a new protocol, a new exchange of messages at the CoAP layer, or new data structures. It defines how protocols standardized by IETF are combined so that ITS stations can communicate with one another using CoAP. Procedures defined to share information between the CoAP layer and other components of the ITS station architecture are defined in ISO 24102 series (Management). In addition to the requirements specified within this document, a number of notes and examples are provided to illustrate CoAP main facilities.
