Definitions
- the invention relates to a method for transmitting files and a communication system for carrying out the method. Furthermore, the invention relates to a computer program and a computer-readable medium.
- Network systems offer the great advantage that a large number of participants can have access to the same data or files. This means that the same files with the same content, such as messages, advertising data or updates, can be transmitted to a large number of different recipients.
- network systems reach technical limits as the number of recipients and the size of the files increases. This can be seen, for example, in the case of a transfer of files between a land-based system and several vehicles. As the number of vehicles that are to receive the same file from the land-based system increases, the volume of data to be transmitted also increases. However, a total transmission capacity is limited by a data transmission rate and possible limited data volumes in the case of communication via a mobile radio network. Therefore, an ever-increasing volume of data to be transferred leads to a risk of bottlenecks in data transmission and failures due to overload. This jeopardizes operational security and reliability when transferring files.
- the object of the invention is to improve the reliability of a file transmission from one communication participant to a large number of communication participants.
- This task is solved using a method according to the features of claim 1.
- this task is solved by a communication system with the characteristics of the secondary system requirement.

- the files can be transferred regardless of whether the communication participants of the second type can be reached.
- a high transmission speed can be provided between a storage device and a communication participant of the second type, which can be significantly increased, in particular in comparison to a direct transfer of the files from the communication participant of the first type to a communication participant of the second type. This means you can easily avoid the need for a cost-intensive expansion of existing communication networks.
- a storage device is selected in accordance with a parameter relating to the respective communication participant of the second type.
