Abstract (en)
Obstacle détection enhancement data have to be transmitted to an on-board wireless radio unit (160) of a moving conveyance (140) travelling on a predefined path (130) and embedding an obstacle détection system (170). The obstacle détection enhancement data are stored in a database (150) and include map descriptors describing knowledge of environment surrounding the predefined path (130). For determining which obstacle détection enhancement data to be transmitted toward the on-board wireless radio unit (160) in a transmission cycle, a server (120) détermines a relevant map portion in the database (150) and prioritizes obstacle détection enhancement data in the determined relevant map portion by attributing a weight thereto. The weights are attributed according to distance information and/or refinement level. The server (120) retrieves from the database (150) the obstacle détection enhancement data to be transmitted in the transmission cycle, so as to fill transmission resources made available thereto, according to the weights thus attributed.
