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.
