ADAPTIVE POSITION REPORTING

1 . A method comprising:

obtaining data indicative of at least a speed of a mobile communication device;

determining a communication scheme for reporting a position of the mobile communication device, the determination of the communication scheme being based on at least the speed; and

causing the mobile communication device to report its position in accordance with the determined communication scheme.

2 . The method of claim 1 , wherein the mobile communication device is associated with a vehicle such that the obtained data or the reported position is indicative of at least a position or speed of the vehicle.

3 . The method of claim 1 , wherein the obtained data or the reported position comprise Global Positioning System (GPS) data.

4 . The method of claim 1 , wherein obtaining data comprises obtaining data that is indicative of at least a position and a speed of each of a plurality of mobile communication devices.

5 . The method of claim 4 , wherein determining the communication scheme comprises identifying a cluster of mobile communication devices from among said plurality of mobile communication devices.

6 . The method of claim 5 , wherein identifying the cluster comprises obtaining said that is indicative of at least a position and a speed of one of the mobile communication devices by another of the mobile communication devices.

7 . The method of claim 4 , wherein determining the communication scheme comprises selecting a representative mobile communication device from the mobile communication devices of the cluster.

8 . The method of claim 1 , wherein determining the communication scheme comprises determining a reporting interval.

9 . The method of claim 8 , wherein a length of the reporting interval increases when the speed decreases.

10 . The method of claim 1 , wherein causing the mobile communication device to report its position comprises communicating the communication scheme to the mobile communication device.

11 . The method of claim 1 , wherein causing the mobile communication device to report its position comprises operating the mobile communication device in accordance with communication scheme.

12 . The method of claim 1 , comprising obtaining infrastructure data.

13 . The method of claim 12 , wherein determination of the communication scheme is additionally based on the obtained infrastructure data.

14 . The method of claim 12 , wherein the infrastructure data comprises a status of a traffic signal.

15 . A system comprising:

a processing unit in communication with at least one mobile communication device and with a computer readable medium, wherein the computer readable medium contains a set of instructions wherein the processing unit is designed to carry out the set of instructions to:

obtain data indicative of at least a speed of said at least one mobile communication device;

determine a communication scheme for reporting a position of said at least one mobile communication device, the determination of the communication scheme being based on at least the speed; and

cause said at least one mobile communication device to report its position in accordance with the determined communication scheme.

16 . The system of claim 15 , wherein said at least one mobile communication device is associated with a vehicle such that the obtained data or the reported position is indicative of a speed or position of the vehicle.

17 . The system of claim 15 , wherein the processing unit is in communication with said at least one mobile communication device via a network.

18 . The system of claim 17 , wherein the network is a wireless network.

19 . The system of claim 17 , wherein the network is a packet-switched network.

20 . The system of claim 15 , wherein the processing unit is in communication with an infrastructure device.
