Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction

With the spread of nomadic and mobile devices such as smart phones and the rapid expansion of indoor spaces, many of the services and facilities related to the transport system have become accessible to indoor spaces. Consequently, navigation in indoor space is considered an increasingly critical functionality for variety of applications, including indoor navigation for vehicles and public-area mobile robots in the transport industry.

The ISO 17438 series are intended to be used by designers, developers and providers of indoor navigation services. The ISO 17438 series define requirements, data model, and encoding format of indoor positioning reference data for supporting indoor navigation in intelligent transport systems. When implemented, this document will:

provide developers and designers with concepts and appropriate information to implement the central ITS station (C-ITS-S) based positioning
provide developers and designers with interoperable ways to use the central ITS station (C-ITS-S) based positioning for indoor navigation;
enable users to be provided with indoor navigation;
provide developers and designers with an extendable base for indoor navigation.

The objective of this document is to define requirements and message specification for central ITS station (C-ITS-S) based positioning required for indoor navigation functionality for ITS applications, as a part of the ISO 17438 series.

1 Scope

This document defines detailed use cases, requirements and message specifications for supporting central ITS station based indoor positioning to provide indoor navigation functionality between a personal/vehicle (P/V) ITS station and the central ITS station.

This document is only applicable to the core flow for the central ITS station based indoor positioning. The following issues which are adjunctive but essential for commercial navigation services are beyond the scope of this document:

authorized and authenticated access of users and services, including security;
payment;
preparation of indoor data which are necessary for indoor navigation;
low-level communication protocols required to transfer and share data from and to a roadside ITS station or a central ITS station;
other issues dependent on implementation of an instance of indoor navigation.
