本文档在ITS中指定了用于一般目的的快速服务公告协议（FSAP）。它引用并支持ISO/TS 16460的所有功能，尤其是支持服务响应消息（SRM）和服务公告消息（SAM）之外的相关功能，SAM只支持非常基本的功能。 FSAP支持通过ITS应用程序标识符（ITS-AID）唯一标识的本地广告ITS服务。 本文件参考ISO/TS 16460规定了信息格式和相关基本协议程序，以及ISO 21217中规定的ITS站中FSAP操作的进一步相关协议要求。 本文件说明了其与ETSI TC its和IEEE规定的服务公告协议的关系。

This document specifies the fast service announcement protocol (FSAP) for general purposes in ITS. It references and supports all features of ISO/TS 16460, especially supporting the service response message (SRM) and related features in addition to the service announcement message (SAM), which enables only very basic features. FSAP supports locally advertised ITS services uniquely identified by an ITS application identifier (ITS-AID). This document specifies message formats and related basic protocol procedures by reference to ISO/TS 16460, and further related protocol requirements for operation of FSAP in the context of an ITS station specified in ISO 21217. This document illustrates its relations to service announcement protocols specified by ETSI TC ITS and IEEE.
