Cellular network based assistant for vehicles

摘要

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.

1. A network entity of a cellular telecommunications network, the network entity comprising circuitry configured to:
define a spatial zone in the cellular telecommunications network; receive first route indication information from a first mobile terminal that is on or within a first vehicle inside the spatial zone; generate a first vehicle trajectory for the first vehicle based on the received route indication information; store an area of possible vehicle trajectories inside the spatial zone; if the received first route indication information is ambiguous:
generate additional first vehicle trajectories for the first vehicle within the stored area of possible vehicle trajectories; andgenerate trajectory probabilities for each additional first vehicle trajectory; calculate a danger situation probability for the first vehicle based on the generated first vehicle trajectories; and send a notification message to the first mobile terminal if the calculated danger situation probability exceeds a predefined threshold probability.
