10、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, go
11、vernmental 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 main
12、tenance 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). Att

18、oduction This part of ISO 24102 is part of a family of International Standards for communications access for land mobiles (CALM). An introduction to the whole set of International Standards for Intelligent Transport Systems (ITS) is provided in ISO 21217. This part of ISO 24102 is the second part of
19、 a multipart International Standard which determines remote management of an ITS station unit (ITS-SU) with the ITS station and communication architecture specified in ISO 21217 and illustrated in Figure 1, and operated as a bounded secured managed domain (BSME). Remote ITS station management has th
20、e purpose of setting, updating, and deletion of configuration and operation information in an ITS station communication units (ITS-SCU) of an ITS station unit (ITS-SU) specified in ISO 21217, e.g. information on policies and regulations, security related information, accounting information, access l

23、erved v Intelligent transport systems Communications access for land mobiles (CALM) ITS station management Part 2: Remote management of ITS-SCUs 1 Scope This part of ISO 24102 provides specifications for Intelligent Transport Systems (ITS) station management to be compliant with the ITS station refe
24、rence architecture and the set of related standards from ISO/TC 204. Remote ITS station management is specified by means of protocol data units (PDUs) and procedures of the “Remote ITS Station Management Protocol” (RSMP) related to managed objects in an ITS station unit. Distinction is made between
25、managed ITS station units (management clients) and managing remote ITS station units (management servers). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

39、etion of configuration and operation information in an ITS station communication unit (ITS-SCU) of an ITS station unit (ITS-SU) specified in ISO 21217, e.g. information on policies and regulations (CEN/ISO/TS 17419), security related information, accounting information, access layer parameters (see
40、Reference 1), etc., installation, update, and deinstallation of persistent information in an ITS-SCU, e.g. ITS-S application processes, ITS-S communication protocols, and notification and retrieval of management information, e.g. log files of events, alarms generated by the ITS-SCU of an ITS-SU. By
41、this, it covers the five management areas identified in ISO/IEC 7498-4. Remote ITS station management covers a set of management processes where ITS station units (ITS- SU) acting as remote management servers (RMS) manage ITS station communication units (ITS-SCU) of managed ITS-SUs acting as remote
42、management clients (RMC). An RMS is associated with an ITS-SCU configuration management centre identified in CEN/ISO/ TS 17419. An RMS may be implemented, e.g. in a roadside ITS sub-system or in a central ITS sub-system. Remote ITS station management is applied to managed objects (according to ISO/I
43、EC 7498-4) in remote management sessions. Such sessions may be initiated by the RMS (server initiated session), e.g. by means of the Fast Service Advertisement Protocol (FSAP) (see Reference 2) or by direct IPv6 based access, or by the RMC (client initiated session), typically using IPv6 communicati
44、ons, as illustrated in Figure 2 (server initiated session using FSAP), in Figure 3 (direct server initiated session), and in Figure 4 (client initiated session). The mechanisms specified in this part of ISO 24102 enable future specifications of remote management features in separate standards or by
45、means of registries.
