Abstract

A device includes a memory to store a plurality of instructions and a processor to execute instructions in the memory to determine a location of a mobile communication device, determine a direction of movement of the mobile communication device, identify other mobile communication devices within a particular distance of the mobile communication device, identify other mobile communication devices moving in a particular direction with respect to the mobile communication device, and store, in the memory, a list of the identified other mobile communication devices.

Claims

1. A device, comprising:

a memory to store a plurality of instructions; and

a processor to execute instructions in the memory to;

determine a location of a mobile communication device,

determine a direction of movement of the mobile communication device,

identify other mobile communication devices within a particular distance of the mobile communication device,

identify other mobile communication devices moving in a particular direction with respect to the mobile communication device, and

store, in the memory, a list of the identified other mobile communication devices.

2. The device of claim 1, where the device is included within the mobile communication device.

3. The device of claim 2, further comprising a Global Positioning System (GPS) receiver, and where the processor is further to determine the location of the mobile communication device using information obtained from the GPS receiver.

4. The device of claim 3, where the processor is further to determine the direction of movement of the mobile communication device using information obtained from the GPS receiver.

5. The device of claim 1, where the device includes a server device remote from the mobile communication device, and where the server device communicates with the mobile communication device via a communications network.

6. The device of claim 5, where the processor is further to determine the location of the mobile communication device using at least one of:

information received by a GPS receiver,

information received from a sensor located within the mobile communication device,

information received from a base station associated with the mobile communication device,

information inputted by a user of the mobile communication device,

information received from sensors associated with the location of mobile communication device, or

previously stored location information.

7. The device of claim 1, further comprising a user interface for sending and receiving messages to the other mobile communication devices included in the list.

8. The device of claim 1, where the list functions as a push to talk over cellular group.

9. A method performed by a device that includes a processor and a memory, the method comprising:

determining, by the processor, a location of a mobile communication device;

determining, by the processor, a direction of movement of the mobile communication device;

identifying, by the processor, other mobile communication devices connected to a communications network associated with the mobile communication device;

filtering, by the processor, the identified other mobile communication devices based on a distance from the location of the mobile communication device;

filtering, by the processor, the identified other mobile communication devices based on direction of movement in relation to the direction of movement of the mobile communication device; and

storing, in the memory, a list of mobile communication devices filtered based on the distance and filtered based on the direction of movement.

10. The method of claim 9, further comprising:

receiving a message from the mobile communication device; and

sending the message to all mobile communication devices on the list.

11. The method of claim 10, further comprising:

receiving identification information identifying a vehicle associated with the mobile communication device; and

including the identification information with the message when sending the message to the mobile communication devices on the list.

12. The method of claim 9, further comprising:

receiving a message from one of the mobile communication devices on the list; and

sending the message to the mobile communication device.

13. The method of claim 12, further comprising:

receiving identification information identifying a vehicle associated with the message; and

providing the identification information, via the message, to the mobile communication device.

14. The method of claim 9, where the location of the mobile communication device is determined based on information obtained from a Global Positioning System (GPS) receiver associated with the mobile communication device.

15. The method of claim 9, where the direction of movement of the mobile communication device includes a direction vector, and where the filtering based on direction is based on a difference in an angle between the direction vector of the mobile communication device and direction vectors of the other mobile communication devices.

16. The method of claim 9, where the filtering based on direction includes selecting all other mobile communication devices that are moving in substantially a same direction as the mobile communication device.

17. The method of claim 9, where the filtering based on direction includes selecting all other mobile communication devices that are moving in substantially an opposite direction from the mobile communication device.

18. The method of claim 9, where filtering based on a distance includes filtering based on at least one of:

information received by a GPS receiver,

information received from a sensor located within the mobile communication device,

information received from a base station associated with the mobile communication device,

information inputted by a user of the mobile communication device,

information received from sensors associated with the location of mobile communication device, or

previously stored location information.

19. The method of claim 9, where filtering based on a direction of movement includes filtering based on at least one of:

location information received at two different points in time;

information received from a sensor located within the mobile communication device;

information inputted by a user of the mobile communication device;

information received from a sensor associated with a location of the mobile communication device;

or

previously stored direction of movement information.

20. A system comprising:

means for determining a location of a mobile communication device based on information obtained by a Global Positioning System (GPS) receiver associated with the mobile communication device;

means for determining a direction of movement of the mobile communication device;

means for identifying other mobile communication devices that are within a particular distance of the mobile communication device;

means for selecting ones of the identified other mobile communication devices that are moving in substantially the same direction as the mobile communication device;

means for receiving a message from the mobile communication device; and

means for providing the message to the selected ones of the other mobile communication devices.
