Abstract
A driver assistant system which is based on a cellular telecommunications network comprises detecting a spatial zone in the cellular telecommunications network; receiving route indication information from a mobile terminal on a vehicle inside the spatial zone with a network entity of the cellular telecommunications network; generating a trajectory for the vehicle based on the received route indication information; calculating a danger situation probability for the vehicle based on the generated trajectory; and sending a notification message to the mobile terminal if the danger situation probability exceeds a predefined threshold probability.
