Abstract: A system for providing a localized information service using an infrastructure of a cellular communication network, the system comprising at least one service source terminal arranged for transmitting a network upload message to the cellular communication network, said network upload message comprising a payload part, a reflection entity of said cellular communication network arranged for receiving said network upload message, for generating one or more reflection messages comprising said payload part, and for sending said reflection messages to a group of service destination terminals that have a predetermined spatial relationship with said service source terminal, and a filter arranged for blocking a further network upload message that has a predetermined context relationship with said network upload message from being sent to the group of service destination terminals.

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.

Abstract: A method of providing a localized information service using an infrastructure of a cellular communication network is described. It comprises a service source terminal transmitting a network upload message to the cellular communication network, said network upload message comprising a payload part, a reflection entity of said cellular communication network receiving said network upload message, generating one or more reflection messages comprising said payload part, and sending said one or more reflection messages to a group of service destination terminals that stand in a predetermined spatial relationship with said service source terminal.
