This document SIST EN ISO 18750:2018:
-describes the functionality of a “Local Dynamic Map”(LDM)in the context of the “Bounded Secured
Managed Domain”(BSMD)；
-specifies:
一 general characteristics of LDM Data Objects (LDM-DOs)that may be stored in an LDM,i.e.
information on real objects such as vehicles,road works sections,slow traffic sections,specialweather condition sections,etc.which are as a minimum requirement location-referenced andtime-referenced;
-service access point functions providing interfaces in an ITS station (ITS-S)to access an LDM for:
-secure add,update and delete access for ITS-S application processes;
-secure read access (query)for ITS-S application processes;
-secure notifications (upon subscription)to ITS-S application processes;
-management access:
-secure registration,de-registration and revocation of ITS-S application processes at LDM;
-secure subscription and cancellation of subscriptions of ITS-S application processes;
-procedures in an LDM considering:
-means to maintain the content and integrity of the data store;
-mechanisms supporting several LDMs in a single ITS station unit.
