Abstract

A method of controlling vehicular wireless communications of an on-board wireless communications unit of a vehicle, comprising: receiving information relating to the number of people and the number of vehicles with on-board wireless communications units in a geographical area; and setting a wireless communications policy defining what vehicular wireless communications are permitted to be transmitted in the geographical area, based on the received information.

Claims

1. A method of controlling vehicular wireless communications of an on-board wireless communications unit of a vehicle, comprising:

receiving information relating to the number of people and the number of vehicles with on-board wireless communications units in a geographical area; and

setting a wireless communications policy defining what vehicular wireless communications are permitted to be transmitted in the geographical area, based on the received information.

2. The method according to claim 1, further comprising:

predicting a change in at least one of the number of people and the number of vehicles with on-board wireless communications units in the geographical area, based on the received information, and

wherein the setting of the wireless communications policy is based on the predicted change.

3. The method according to claim 1, wherein the method is performed by a central computing device, the central computing device generating a signal for transmission to vehicles with on-board wireless communications units to cause them to implement the wireless communications policy when in the geographic area.

4. The method according to claim 1, wherein the wireless communications policy defines which of a plurality of different types of data is permitted to be transmitted in the geographic area, the plurality of different types of data being classified according to how long transmission can be delayed.

5. The method according to claim 4, wherein the plurality of different types of data comprises a first type of data that is permitted to be transmitted in the geographic area at any time, a second type of data that is permitted to be transmitted in the geographic area only when there are no restrictions on vehicular wireless communications in the geographic area, and a third type of data of which at least a portion is permitted to be transmitted in the geographic area only after a predetermined time has expired.

6. The method according to claim 5, wherein the wireless communications policy defines which portion of the third type of data is permitted to be transmitted after the predetermined time has expired, the portion comprising at least one of:

the oldest buffered data since the last transmission, and the most recent buffered data since the last transmission.

7. The method according to claim 4, wherein the plurality of different types of data is organized into a plurality of communication restriction levels according to the type of data.

8. The method according to claim 1, further comprising:

monitoring a location of the vehicle;

determining that the vehicle is in the geographic area, based on the monitored location; and

controlling vehicular wireless communications of the on-board wireless communications unit in accordance with the wireless communications policy when it is determined that the vehicle is in the geographic area.

9. The method according to claim 1, wherein the received information comprises real-time, or near real-time, tracking information.

10. The method according to claim 1, wherein the received information comprises at least one of information indicating travel to or from the geographic area by at least one of people and vehicles with on-board wireless communications units at a past or future point in time.

11. A device for controlling vehicular wireless communications of an on-board wireless communications unit of a vehicle, comprising:

a processor; and

memory storing instructions which, when executed by the processor, cause the processor to;

set a wireless communications policy defining what vehicular wireless communications are permitted to be transmitted in a geographical area, based on received information relating to the number of people and the number of vehicles with on-board wireless communications units in a geographical area.

12. The device according to claim 11, wherein the device is a central computing device.

13. A method of controlling vehicular wireless communications by an on-board unit of a vehicle, comprising:

monitoring a location of the vehicle;

determining that the vehicle is in the geographic area, based on the monitored location; and

controlling vehicular wireless communications of the on-board wireless communications unit in accordance with a wireless communications policy defining what vehicular wireless communications are permitted in the geographic area, when it is determined that the vehicle is in the geographic area.

14. An on-board wireless communications unit for a vehicle, comprising:

wireless communications circuitry;

a processor; and

memory storing instructions which, when executed by the processor, cause the processor to;

monitor a location of the vehicle, determine that the vehicle is in the geographic area, based on the monitored location, and control wireless communications of the on-board wireless communications unit in accordance with a wireless communications policy defining what vehicular wireless communications are permitted in the geographic area, when it is determined that the vehicle is in the geographic area.

15. A vehicle having the on-board wireless communications unit of claim 14.
