1 Scope
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 can be stored in an LDM, i.e. information on real objects such as
vehicles, road works sections, slow traffic sections, special weather condition sections,
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 for maintaining the content and integrity of the data store;
— mechanisms supporting several LDMs in a single ITS station unit.
