标准摘要
[中文适用范围]： 本文件将 OCC（光学摄像机通信）指定为适用于符合 ISO 21217 的 ITS 站的本地化通信的接入技术。 OCC 接入技术是为 ISO 21218 的实施环境指定的。 本文件提供了名为“ITS-OCC”。 本文件规定了 IEEE 802.15.7:2018 的补充和偏差，以便使 ITS-OCC CI 兼容： ——ISO 21217 中规定的 ITS 站和通信架构，以及 — ISO 中规定的混合通信支持21218. 本文件规定： ——用于 C-ITS 的 IEEE 802.15.7:2018 OCC 配置文件； ——CAL 详细信息（ISO 21218）； ——MAE 详细信息（ISO 21218、ISO 24102-3）。 注：考虑到涉及基于 OCC 执行的车辆与路边站之间的通信的安全相关服务，值得注意的是，由于屏蔽，通信可能会中断或阻塞很长一段时间。 [外文原描述]： 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.
