Method for transmitting a data packet from a central electronic computing device to at least one mobile terminal device, and network system

1. A method for transmitting a data packet from a central electronic computing device to at least one mobile terminal device via a network system, the method comprising:

transmitting the data packet to an electronic computing device of a motor vehicle of the network system via a mobile telecommunications network; and

transmitting the data packet locally from the electronic computing device to the at least one mobile terminal device via a local network, wherein the local network is created by the electronic computing device,

wherein the data packet is transmitted to another electronic computing device of another motor vehicle and, as a function of a first distance of the at least one mobile terminal device from the motor vehicle and of a second distance of the at least one mobile terminal device from the another motor vehicle, the central electronic computing device determines whether the electronic computing device or the another electronic computing device locally transmits the data packet to the at least one mobile terminal device.

2. The method of claim 1 , wherein based on traffic networking technology, the transmitted data packet is transmitted locally to the at least one mobile terminal device.

3. The method of claim 2 , wherein the traffic networking technology is a cellular vehicle-to-everything technology.

4. The method of claim 1 , wherein the data packet is transmitted from the electronic computing device to the at least one mobile terminal device, which is located in the vicinity of the electronic computing device.

5. The method of claim 1 , wherein as a function of a respective mobile telephony bandwidth of the motor vehicle and of the another motor vehicle, it is determined whether the electronic computing device or the another electronic computing device locally transmits the data packet to the at least one mobile terminal device.

6. The method of claim 1 , wherein, in an event of an incomplete transfer of the data packet from the electronic computing device to the at least one mobile terminal device, the transmission process is taken over by the another electronic computing device of the another motor vehicle of the network system.

7. The method of claim 6 , wherein in the event of the incomplete transfer of the data packet by the another electronic computing device, the incomplete transfer is communicated in an information packet, and an untransmitted part is transmitted from the another electronic computing device to the at least one mobile terminal device.

8. The method of claim 7 , wherein the information packet is signed cryptographically by the electronic computing device or the information packet is encrypted asymmetrically by the electronic computing device.

9. The method of claim 7 , wherein taking-over of transmission of the data packet from the other electronic computing device by the electronic computing device or means of the other electronic computing device is communicated to the central electronic computing device.

10. The method of claim 1 , wherein the data packet is divided by the central electronic computing device or by the electronic computing device into at least two partial data packets, and wherein the at least two partial data packets are in each case transmitted to the at least one mobile terminal device and another mobile terminal device, wherein the partial data packet is processed by a respective mobile terminal device.

11. The method of claim 10 , wherein a respective processed partial data packet is transmitted from the at least one mobile terminal device back to the electronic computing device or to the central electronic computing device.

12. A network system, comprising:

at least one mobile terminal device;

a central electronic computing device; and

at least one motor vehicle with an electronic computing device,

wherein the network system the central electronic computing device is configured to transmit a data packet to the electronic computing device of the at least one motor vehicle via a mobile telecommunications network, and

wherein the electronic computing device is configured to transmit the data packet locally to the at least one mobile terminal device via a local network, and

wherein the electronic computing device is configured to create the local network,

wherein the data packet is transmitted to another electronic computing device of another motor vehicle and, as a function of a first distance of the at least one mobile terminal device from the motor vehicle and of a second distance of the at least one mobile terminal device from the another motor vehicle, the central electronic computing device determines whether the electronic computing device or the another electronic computing device locally transmits the data packet to the at least one mobile terminal device.
