Abstract

Restrictions on use of a cellular telephone in a vehicle, such as an automobile, are imposed using a global position system (GPS) device to determine the location of a vehicle in relation to geographic regions in which legal or customer restrictions on cellular telephone use are to be imposed. Network or local short-range wireless transmitters supply information to a cellular telephone describing potentially applicable restriction information retrieved from network databases. In response, a cellular telephone determines applicability of such restrictions and applies them to further use of the cellular telephone while such restrictions continue to apply. Alternative arrangements allow vehicle-based or network based processing of region and restrictions information to yield command messages to cellular telephones to control their further use.

Claims

1. A method for controlling the use of a portable communications device comprising

deriving information relating to the geographic location of the personal communications device,

at the personal communications device, receiving region information relating to restrictions on use of personal communications devices in each of a plurality of geographic regions likely to be of interest,

storing the region information in a region table in the personal communications device;

determining whether the geographic location of the personal communications device bears a predetermined relationship to at least one of the geographic regions of the stored region information, and

enforcing the restrictions on the use of the personal communications device while the predetermined relationship exists;

wherein the region information includes legal restrictions imposed by a governmental authority on personal communications device use particular to at least one of the plurality of geographic regions.

2. The method of claim 1 wherein the deriving information relating to the geographic location of the personal communications device comprises deriving information from a global positioning satellite (GPS) receiver.

3. The method of claim 2 wherein the GPS receiver is included in the personal communications device.

4. The method of claim 2 wherein the GPS receiver is installed in a vehicle.

5. The method of claim 1 wherein receiving region information and storing region information are performed upon power-up of the personal communications device.

6. The method of claim 1 wherein receiving region information and storing region information are performed upon the personal communications device passing between wireless cells.

7. The method of claim 1 wherein storing region information further comprises overwriting at least some previously stored region information.

8. The method of claim 1 wherein the region information includes boundary definitions for at least one of the plurality of geographic regions.

9. The method of claim 1 wherein the use of a personal communications device is pursuant to an arrangement with a communications carrier, and the region information includes restrictions imposed by a customer of the carrier.

11. The portable communication device of claim 9 wherein the means for deriving information relating to the geographic location of the personal communications device comprises a means for deriving information from a global positioning satellite (GPS) receiver.

12. The portable communication device of claim 11 further comprising the GPS receiver.

13. The portable communication device of claim 11 wherein the GPS receiver is installed in a vehicle.

14. The portable communication device of claim 9 wherein the means for receiving region information and storing region information perform those functions upon power-up of the personal communications device.

15. The portable communication device of claim 9 wherein the means for receiving region information and storing region information perform those functions upon the personal communications device passing between wireless cells.

16. The portable communication device of claim 9 wherein the means for storing region information further comprises means for overwriting at least some previously stored region information.

17. The portable communication device of claim 9 wherein the region information includes boundary definitions for at least one of the plurality of geographic regions.

10. A portable communications device, comprising:

means for receiving information relating to the geographic location of the personal communications device,

means for receiving region information relating to restrictions on use of personal communications devices in each of a plurality of geographic regions likely to be of current interest,

a region table for storing the region information in the personal communications device;

means for determining whether the geographic location of the personal communications device bears a predetermined relationship to at least one of the geographic regions of the stored region information, and

means for enforcing the restrictions on the use of the personal communications device while the predetermined relationship exists;

wherein the region information includes legal restrictions imposed by a governmental authority on personal communications device use particular to at least one of the plurality of geographic regions.

18. The portable communication device of claim 10 wherein the use of a personal communications device is pursuant to an arrangement with a communications carrier, and the region information includes restrictions imposed by a customer of the carrier.
