7、ndardization) 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 righ
8、t 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
9、 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 rul
10、es of the ISO/IEC Directives, Part 2. www.iso.org/directives Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

37、functions Basic primitive application functions are an essential element of legacy CIs according to option 2 specified in Annex B. They are related to on-board units resources such as human-machine interface, IC card interface and so on. Each basic primitive application function is uniquely addresse
38、d by a port number. A roadside station selects and combines basic primitive application functions, see Figure B.2, in order to realize a specific service. Examples of the basic primitive application functions are shown in Annex C. NOTE Basic primitive application functions are executed on LPP. 6 Con
