wherein Rk represents a ratio of downlink transmission resources allocated to the moving conveyance identified by k with respect to a total quantity Rtot of downlink transmission resources,
wherein Dk=Rk·Kk and Kk=Rtot·f(SNRk)/bk 
and wherein f(SNRk) represents the quality Qk of the wireless link between the on-board wireless radio unit of the moving conveyance identified by k and the server as function of signal-to-noise ratio SNRk on said wireless link.
