SENDING OF DATA FROM A VEHICLE SUPPORT CENTRE TO A VEHICLE

摘要

The present invention provides a way for a vehicle support centre (16) to send data to a vehicle (10) via a radio communication network (14) supporting packet based communication. The vehicle requests communication from the network and sends registration packets (P1) according to a connectionless communication protocol to the vehicle support centre regularly at a fixed interval, where the interval is short enough for the probability to be high of each registration packet receiving a dynamic source connectivity identity that is the same. The vehicle support centre (16) receives registration packets (P1), when receiving a first registration packet having a new dynamic connectivity identity, associates the dynamic connectivity identity with the vehicle, checks, when receiving at least some registration packets, if there is any data to be sent to the vehicle and sends such possible data in a return packet (P2) with the dynamic connectivity identity as destination address.
