Intelligent transport systems — Communications access for land mobiles (CALM) — Management
ISO 24102:2010 provides specifications for intelligent transport systems (ITS) station management to be compliant with the ITS station reference architecture and the set of communications access for land mobiles (CALM) related standards. Management actions are specified via service access points; messages and data that flow between the ITS station management entity and the security entity, the application entity and the various communication protocol layers of the ITS station reference architecture; and protocol data units for management communications between addressable instances of functionality of an ITS station.

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.
ISO 24102 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.

5 Requirements
The ITS station management entity specified in this International Standard provides functionality related to the
⎯ management of communication protocol layers and the security entity presented in the ITS station
reference architecture specified in ISO 21217 and presented in Figure 1, and
⎯ station-local management communications (Inter-ITS-SCU communications) enabling a sub-division of an
ITS station into several addressable entities, e.g. hosts and routers,
in line with the general ITS architecture specified in ISO 21217.

---------------------- Page: 10 ----------------------
ISO 24102:2010(E)
ITS station management is specified as a distributed process, where no supervisory entity is employed.
The ITS station management entity shall provide the service primitives of the
a) MI-SAP, specified in ISO 21218,
b) MN-SAP, specified in this International Standard,
c) MF-SAP, specified in this International Standard.
NOTE 1 SAPs can be non-exposed interfaces. Thus service primitives of SAPs are not subject to conformance tests.
NOTE 2 The MA-interface presented in Figure 1 is not specified in this International Standard, although it is recognized
as part of the ITS station reference architecture specified in ISO 21217.
The ITS station management entity shall use the service primitives provided in the NF-SAP, specified in
ISO 29281 and in ISO 21210 for the purpose of "Inter-ITS-SCU Communication".
NOTE 3 Figure 18 in ISO 21217 presents details on the ITS-SCU, i.e. an extension on the basic ITS station reference
model presenting the NF-SAP connected to the management entity.
Means to secure the access to management functionality need to be specified within the global context of
CALM security. This may require, e.g. defining further Inter-ITS-SCU communication PDUs for authentication
of ITS-SCUs. Details are outside the scope of this International Standard.
Detailed mandatory requirements are specified in the following clauses of this International Standard.
⎯ Clause 6 specifies "Inter-ITS-SCU communications", i.e. how management commands are exchanged
between different addressable entities of an ITS station.
⎯ Clause 7 specifies basic management procedures related to communication interfaces.
⎯ Clause 8 specifies groupcast management.
⎯ Clause 9 specifies FAST service provisions.
⎯ Clause 10 specifies congestion control.
⎯ Clause 11 specifies the concept of "Radar View" and the link to the "Local Dynamic Map" (LDM)
application.
⎯ Clause 12 specifies communication interfaces (CI) selection management.
⎯ Clause 13 specifies management of "Legacy CIs".
⎯ Clause 14 specifies management data elements.
⎯ Clause 15 specifies the MN-SAP of the networking and transport layer.
⎯ Clause 16 specifies the MF-SAP of the facilities layer.
⎯ Clause 17 specifies conformance declaration and test methods.
⎯ Annexes provide further mandatory requirements.

6 Inter-ITS-SCU communication
6.1 Basics
Management communications between ITS-SCUs of the same ITS station, as specified in ISO 21217, shall be
based on the ITS station-internal network presented in ISO 21217.
NOTE Installations can provide technically different realizations of the ITS station internal network which can be used
to carry inter-ITS-SCU management packets. Details are outside the scope of this International Standard.
The following protocol data units (PDU) shall be used:
⎯ ITS-SCU-Mngmt-Request;
⎯ ITS-SCU-Mngmt-Response.
Details on parameters of these PDUs are shown in Table 1.
