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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
This International Standard is part of a family of International Standards for CALM (Communications Access
for Land Mobiles) which specify a common architecture, network protocols and a set of air interface definitions
for wireless communications using a number of wireless media, including cellular second generation, cellular
third generation, 5 GHz, millimetre, infra-red communications, and mobile wireless broadband (MWB), over
packet-based networks. The CALM architecture is also designed to include short range, short duration, low
latency communication systems such as European Dedicated Short-Range Communications (DSRC) and
North American Wireless Access in Vehicular Environments (WAVE) based on IEEE 802.11. It is anticipated
that other air interfaces will be added in the future. Generally speaking, the CALM architecture is designed to
include air interfaces that provide some subset of point-to-point, vehicle-to-vehicle, and vehicle-to-point
communications over packet-based networks in the ITS Sector. In particular, this International Standard
provides additional specifications which wireless devices adhering to the mobile wireless broadband
IEEE 802.20 techniques standard must also meet to be CALM compliant.
Large volumes of data are required for purposes such as safety, traffic information and management; video
downloads to vehicles for tourist information and entertainment and navigation-system-updates, etc. In order
to support such services, mobile units need to be able to communicate over longer ranges with access
points/base stations, and the system must be able to hand over sessions from one access point/base station
to another. CALM standards are explicitly designed to enable quasi-continuous data communications as well
as data communications of protracted duration between vehicles and service providers, and between vehicles.
It is important to note that the CALM architecture is specifically designed to support packet-based
communications; support for circuit-switched communications is not included.
The fundamental advantage of the CALM concept over traditional systems is the ability to support
media-independent handover (MIH), also referred to as heterogeneous handover, between the various media
that can be included in a CALM system. Selection policies are supported that include user preferences and
media capabilities in making decisions as to which media to use for a particular session, and when to hand
over between media or between service providers on the same medium. These handover mechanisms are
defined within the CALM architecture International Standard (ISO 21217), the CALM IPv6 Networking for
internet connectivity International Standard (ISO 21210), the CALM medium service access points
International Standard (ISO 21218) and the CALM communication and station management International
Standard (ISO 24102). Handovers between access points using the same technology and service provider
use mechanisms that are defined within the particular medium specific CALM Standard.
ITS applications that can be enhanced or are enabled by the CALM architecture include car-to-car and point-
to-multipoint safety messaging, collision avoidance, update of roadside telemetry and messaging, probe data
collection, general internet access, image and video transfer, infotainment, multimedia multicast, traffic
management, monitoring and enforcement in mobile situations, and route guidance, just to mention a few.
For a general introduction to CALM architecture, see ISO 21217.
This International Standard provides definitions and procedures for the establishment and maintenance of an
ITS communications session within a CALM system environment using a medium communication in
accordance with the IEEE 802.20 protocol specification.

This International Standard specifies the options appropriate for CALM using mobile wireless broadband
(MWB) techniques conforming to the IEEE 802.20 air interface and protocol specification recommended by
ITU-R M.1801 and specifies the management interface requirements.
CALM links are required for quasi-continuous, prolonged and short duration communications between
vehicles and the roadside, between vehicles, and between mobile equipment and fixed infrastructure points,
over medium and long ranges.
Wherever practicable, this International Standard has been developed by reference to suitable extant
standards, adopted by selection. Required regional variations are provided.
Application specific upper layers are not included in this International Standard, but will be driven by
application standards.
2 Conformance
In order to claim conformance with this International Standard, mobile wireless broadband techniques
standardized using the IEEE 802.20 protocol specification shall be established in full compliance with local
telecommunications procedures and protocols for IEEE 802.20 in accordance with IEEE standards, and shall
also conform to the requirements of ISO 21217, ISO 21210, ISO 21218, ISO 24102 and ISO 25111.
