Standards Development

Scope

This document specifies guidelines and requirements for the ITS facility layer service "Facilities service handler" (FSH).

Purpose

This multipart standard 24854 is dedicated to ITS facilities layer services.

Part 1 of this multipart standard 24854 provides the basic architecture of ITS facilities layer services and general requirements, applicable for parts 2 through 6 of 24854. So far, three facilities layer services (“communication profile handler”, “content subscription handler”, and “facilities service handler”) are specified in ISO/TS 17429:2017. Parts 2, 3, and 4 of this multipart standard 24854 are dedicated to these three facilities layer services from ISO/TS 17429:2017, and will replace ISO/TS 17429:2017.

Part 5 of this multipart standard 24854 is dedicated to ITS message sets. ITS message sets are uniquely identified by a Message Set Identifier ITS-MsgSetID specified in ISO 17419. Technical details on message sets, i.e. how to create and use them, are still missing. First values of ITS-MsgSetID are already assigned, thus the technical details are urgently needed. Part 6 of this multipart standard 24854 is dedicated to the new ITS facilities layer service “segmentation at the ITS facilities layer”
