本文件规定OCC（光学摄像机通信）是适用于符合ISO 21217的车站的本地化通信的接入技术。OCC接入技术适用于ISO 21218的实施环境。本文件提供了名为“ITS-OCC”的通信接口（CI）的规范。本文件规定了对IEEE 802.15.7:2018的补充和偏离，以使ITS-OCC CIs与以下内容兼容:-ISO 21217中规定的ITS站和通信架构，以及-ISO 21218中规定的混合通信支持。本文件规定:-用于C-ITS的IEEE 802.15.7:2018 OCC配置文件；-CAL的详细信息（ISO 21218）；和-MAE的详细信息（ISO 21218、ISO 24102-3）。注:考虑到涉及在OCC基础上执行的车辆和路边车站之间通信的安全相关服务，需要注意的是，由于阴影，通信可能会中断或阻塞很长时间。

This document specifies OCC (Optical Camera Communication) as an access technology for localized communications applicable in ITS stations conforming with ISO 21217.OCC access technology is specified for the implementation context of ISO 21218. This document provides specifications of a communication interface (CI) named "ITS-OCC".This document specifies the additions to and deviations from IEEE 802.15.7:2018 which are required in order to make ITS-OCC CIs compatible with:— the ITS station and communication architecture specified in ISO 21217, and— the hybrid communications support specified in ISO 21218.This document specifies:— an OCC profile of IEEE 802.15.7:2018 for usage in C-ITS;— details of CAL (ISO 21218); and— details of MAE (ISO 21218, ISO 24102-3).NOTE Considering safety-related services involving communications between a vehicle and a roadside station being performed on the basis of OCC, it is noted that, due to shadowing, communications can be interrupted or blocked for a significantly long time.
