Abstract

Claims (24)

1. A communication method comprising:

detecting or estimating a decrease in throughput of a first communication terminal mounted on a first vehicle that is remotely driven; and

reducing a communication speed of a second communication terminal with which the first communication terminal shares a communication resource in response to detection or estimation of the decrease in the throughput, wherein

the second communication terminal is a communication terminal mounted on a second vehicle that is remotely driven,

the first vehicle is a vehicle having a higher communication priority than the second vehicle, and

the communication priority is high as delay allowance for usage of the vehicle is low.

2. The communication method according to claim 1 , wherein reducing the communication speed of the second communication terminal is stopping communication of the second communication terminal.

3. The communication method according to claim 1 , wherein the communication resource is allocated between the first vehicle and the second vehicle according to the communication priority.

4. A communication method comprising:

detecting or estimating a decrease in throughput of a first communication terminal mounted on a first vehicle that is remotely driven; and

reducing a communication speed of a second communication terminal with which the first communication terminal shares a communication resource in response to detection or estimation of the decrease in the throughput, wherein

the second communication terminal is a communication terminal mounted on a second vehicle that is remotely driven,

the first vehicle is a vehicle having a higher communication priority than the second vehicle, and

the communication priority is high as a charge class of the vehicle is high.

5. The communication method according to claim 4 , wherein reducing the communication speed of the second communication terminal is stopping communication of the second communication terminal.

6. The communication method according to claim 4 , wherein the communication resource is allocated between the first vehicle and the second vehicle according to the communication priority.

7. A communication method comprising:

detecting or estimating a decrease in throughput of a first communication terminal mounted on a first vehicle that is remotely driven; and

reducing a communication speed of a second communication terminal with which the first communication terminal shares a communication resource in response to detection or estimation of the decrease in the throughput, wherein

the second communication terminal is a communication terminal mounted on a second vehicle that is remotely driven,

the first vehicle is a vehicle having a higher communication priority than the second vehicle, and

the communication priority is high as a vehicle speed of the vehicle is high.

8. The communication method according to claim 7 , wherein reducing the communication speed of the second communication terminal is stopping communication of the second communication terminal.

9. The communication method according to claim 7 , wherein the communication resource is allocated between the first vehicle and the second vehicle according to the communication priority.
