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
Most of the application services in the ITS sector use a variety of wide area communication systems in order
to connect user terminals and “Service Centres”. In addition, the application services that are currently being
provided connect specific user terminals to specific service centres using specific wide area communications
systems. In other words, the various conditions that must be established to provide services are fixed.
However, when the future modes of service use are considered, it is assumed that a user will utilize the same
terminal to access “Service Centre A” in some cases and “Service Centre B” in other cases. It can also be
assumed that in some cases the user may be on foot and in others he or she may be travelling in a vehicle. It
can also be assumed that some users may access the service centre from “smart phones”, while others may
do so from navigation systems, while still others may do so using interactive TVs.
When a variety of user terminals use a variety of wide area communications systems to connect to a variety of
service centres in this manner, the type and content of the conditions that must be established will differ for
each individual service usage. In order to provide appropriate service based on these conditions, it is crucial to
establish a mechanism by which the type of conditions and the content established for them are transmitted to
an appropriate entity and interpreted.
This International Standard summarizes information as a checklist to consider internal processing in
communication systems, terminals and so forth (“protocol management information”) suitable for providing ITS
application services utilizing wide area communication systems.

INTERNATIONAL STANDARD ISO 15662:2006(E)
Intelligent transport systems — Wide area communication —
Protocol management information
1 Scope
This International Standard provides information as a checklist to consider handling messages that are
defined by the application working groups of ISO/TC 204, installing systems and selecting suitable wide area
communication systems for providing ITS application services.
The usages of this information are for frameworks of message headers, pay load items for initializing
communication links, checklists for system design and so on. Thus, these information items are not
necessarily contained in message instances and/or headers that are actually transmitted.
For example, this information is used to organize the characteristics of messages such as those requesting
hand-over based on the relationship between the size of the information service area and the communication
range of each communication system (see Figure 1).

ISO/TC 204, installing systems and selecting suitable wide area communication systems for providing ITS
application services
NOTE Protocol management information items are not necessarily contained in message instances and/or headers
that are actually transmitted.
4 Requirements for protocol management information items
Protocol management information is defined as follows and its structure is described in Annex A. Each item is
defined in the abstract, so it does not specify location and time reference manner, granularity and so on. If
some service providers use them for message headers, they shall define the code strictly.
4.1 Selection of communication system
This information is for selecting the wide area communication system to be used for the response in
accordance with the requirements for executing the application service, the usage environment of the service
user, the status of the user terminal and so forth.
4.1.1 Responsiveness
4.1.1.1 Descriptive name
ProtocolManagementInformation. responsiveness
4.1.1.2 ASN.1 object identifier
{iso(1) standard(0) iso15662(15662) protocolManagementInformation(1)
selectionOfCommunicationSystem(1) responsiveness(1)}
4.1.1.3 Definition
This information represents the response speed and allowed delay time while receiving services in terms of
whether response will take place in real time and how much delay time will be allowed.
In cases where response time is conditioned for executing application services, the wide area communication
system shall be selected in accordance with the required response time, and this information can be used to
make such assessment. Furthermore, in case of receiving information in an “on demand” mode, this
information indicates the time from request until reception, for emergency bulletins, it indicates the time until
the information reaches the other party, and for transportation support and the like, it indicates the time until
forward road status, pavement status or other services are completed.

selectionOfCommunicationSystem(1) directionality(2)}
4.1.2.3 Definition
This information indicates the combinations of unidirectional or bidirectional and symmetric or asymmetric with
respect to transmission and reception of information.
In cases where the directionality of communications (unidirectional, interactive, etc.) is needed to execute
application services, the wide area communication system shall be selected in accordance with the type of
communication (unidirectional or bidirectional, symmetric or asymmetric), and this information can be used to
make such assessment. Furthermore, interactive indicates cases where a response is expected to a given
message, while unidirectional indicates cases where a response is not expected to a message.
The following depict combination examples:
⎯ Unidirectional: In the case of an uplink, this corresponds to information provided from the vehicle such as
emergency bulletins. In the case of a downlink, it corresponds to cases in which the service user cannot
(or does not need to) make a request in order for the service provider to make the decision to start
service.
⎯ Interactive-symmetric: When service begins in response to a request from the service user and the
amount of data being transmitted and data being received is almost equal.
⎯ Interactive-asymmetric (large uplink): When service begins in response to a request from the service user
and when the amount of data being transmitted is greater than the amount of data being received.
⎯ Interactive-asymmetric (large downlink): When service begins in response to a request from the service
user and when the amount of data being received is greater than the amount of data being transmitted.
