Patent ID: 8270292

Claim:
A method for transmitting data between a rail vehicle and a railway operational control center, comprising: differentiating data to be transmitted between data of high significance and data of subordinate significance; for a period of time in which a broadband transmission path is available, automatically activating the broadband transmission path and deactivating a previous transmission path; and transmitting data of high significance and subordinate significance between the rail vehicle and the operational control center via said broadband transmission path; for a period of time in which a broadband transmission path is not available, ascertaining a type of data to be transmitted; ascertaining transmission paths suitable for the type of data; successively using said suitable transmission paths to ascertain the availability of a receiver at said railway operational control center; transmitting data of high significance, upon a transmission path being ascertained via which the receiver is available, via the ascertained transmission path between the rail vehicle and the operational control center; and ascertaining, upon the receiver not being available via any of the previously ascertained transmission paths, at least one new transmission path and then using the at least one new transmission path to ascertain the availability of the receiver.
