This document:
-describes the functionality of a "Local Dynamic Map" (LDM) in the context of the "Bounded Secured
Managed Domain" (BSMD);
-specifies:
-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, special
weather condition sections, etc. which are as a minimum requirement location-referenced and
time-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.
