标准摘要
[中文适用范围]: 本文件规定: ——本地化消息(LM)格式:网络和传输层协议的 NPDU,不支持通过网络路由数据包; ——服务广告消息(SAM):例如,要在 LM 中传输的 APDU; ——服务响应消息(SRM):例如,APDU 确认 SAM 提供基于要在 LM 中传输的 ITS 应用类别 [2] 的服务; ——相关程序的基本要求。 部分规范是根据 IEEE 1609.3(TM)-2016 的规范参考制定的。 注:这些消息格式规范和基本程序需要根据使用环境(即 ISO 21217 中指定的 ITS 站,或 IEEE 1609.0[13] 或任何其他上下文中指定的 WAVE 设备)由完整的程序和 SAP 规范来补充。 [外文原描述]: This document specifies: — the Localized Message (LM) format: an NPDU of a networking & transport layer protocol that does not support routing of a packet through a network; — the Service Advertisement Message (SAM): an APDU to be transported in an LM, for example; — the Service Response Message (SRM): an APDU acknowledging a SAM that offered a service based on an ITS application class [ 2 ] to be transported in an LM, for example; — related basic requirements for procedures. Specifications are partly done by normative references to IEEE 1609.3(TM)-2016. NOTE These message format specifications and basic procedures need to be complemented by complete procedures and SAP specifications according to the context of usage, i.e. an ITS station specified in ISO 21217, or a WAVE device specified in IEEE 1609.0 [13] or any other context.
