This document:
u000b— describes the functionality of a "local dynamic map" (LDM) in the context of the "bounded secured managed domain" (BSMD);
u000b— specifies:
u000b— 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;
u000b— service access point functions providing interfaces in an ITS station (ITS-S) to access an LDM for:
u000b— secure add, update and delete access for ITS-S application processes;
u000b— secure read access (query) for ITS-S application processes;
u000b— secure notifications (upon subscription) to ITS-S application processes;
u000b— management access:
u000b— secure registration, de-registration and revocation of ITS-S application processes at LDM;
u000b— secure subscription and cancellation of subscriptions of ITS-S application processes;
u000b— procedures in an LDM considering:
u000b— means for maintaining the content and integrity of the data store;
u000b— mechanisms supporting several LDMs in a single ITS station unit.
