Intelligent transport systems — Vehicle interface for provisioning and support of ITS services — Part 2: Unified gateway protocol (UGP) requirements and specification for vehicle ITS station gateway (V-ITS-SG) interface

ISO 13185-2:2015 specifies the requirements of an ASN.1-based protocol between a vehicle-ITS-Station Gateway (V-ITS-SG) and a nomadic and/or mobile device (ND) to easily exchange vehicle information data. The ASN.1-based protocol has been specified to support a wired or wireless connection between the ND and V-ITS-SG. The Unified Gateway Protocol (UGP) is used between the V-ITS-SG and the ND. UGP supports several features in order to provide · authorization (data privacy), · secured access, · V-ITS-SG and in-vehicle ECUs identification, · real-time vehicle data parameters with identifier and type information in ASN.1 format, and · enhanced vehicle data parameters with identifier and type information in ASN.1 format.

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 documents 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
This part of ISO 13185 has been established to define the requirements of a common software interface
to a vehicle gateway to easily exchange vehicle information data amongst nomadic and/or mobile device,
vehicle gateway, and the vehicle’s Electronic Control Units (ECUs).
Applications supporting service provision use via nomadic and mobile devices need vehicle information
data through an in-vehicle interface access method, as well as the harmonization of existing standards
to support a single vehicle data access solution.
This document defines an ASN.1-based protocol between the nomadic and/or mobile device (ND) and
the UGP Server (implemented in the V-ITS-SG) in the vehicle.
To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in
ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers.
This part of ISO 13185 can be used by vehicle manufacturers for future vehicle design to support the
design of vehicle gateways to interface with NDs.
The ND applications need vehicle information data through an in-vehicle interface access method
(V-ITS-S with V-ITS-SG).
This part of ISO 13185 supports ITS applications which are based on ND in vehicles to operate on a
common software interface to a V-ITS-SG to easily exchange vehicle information data among ND, vehicle
V-ITS-SG, and ECUs.
The protocol implementation in the vehicle gateway features the following:
— the deny of access to the vehicle gateway data by unauthorized on-board and off-board test equipment;
— the deny of access to parts of the vehicle gateway data by unauthorized on-board and off-board test
equipment (privacy);
— the identification of the vehicle gateway and the vehicle it is installed in;
— the list of in-vehicle connected ECUs to the vehicle gateway and their data parameters;
— methods to configure the access to vehicle data.

Intelligent transport systems — Vehicle interface for

Part 2:
Unified gateway protocol (UGP) requirements and

interface
1 Scope
This part of ISO 13185 specifies the requirements of an ASN.1-based protocol between a vehicle-
ITS-Station Gateway (V-ITS-SG) and a nomadic and/or mobile device (ND) to easily exchange vehicle
information data.
The ASN.1-based protocol has been specified to support a wired or wireless connection between the ND
and V-ITS-SG.
The Unified Gateway Protocol (UGP) is used between the V-ITS-SG and the ND. UGP supports several
features in order to provide
— authorization (data privacy),
— secured access,
— V-ITS-SG and in-vehicle ECUs identification,
— real-time vehicle data parameters with identifier and type information in ASN.1 format, and
— enhanced vehicle data parameters with identifier and type information in ASN.1 format.
