reporting the location of the first mobile communication device and the location of the second mobile communication device, wherein at least one of determining the location of the first mobile communication device, determining the location of the second mobile communication device, or reporting the location of the first mobile communication device and the second mobile communication device is repeatedly performed at a frequency, wherein the frequency depends, at least in part, on a characterization of a crowd size associated with the location of the first mobile communication device such that when the location of the first mobile communication device is characterized as being associated with a large crowd size, the frequency is higher than when the location of the first mobile communication device is characterized as being associated with a small crowd size.

9. The computer-readable storage device of claim 8 , wherein the operations further comprise detecting a presence of the second mobile communication device located within the proximity of the first mobile communication device, wherein detecting the presence of the second mobile communication device comprises receiving a short-range radio signal from the second mobile communication device.

10. The computer-readable storage device of claim 9 , wherein determining the location of the second mobile communication device comprises determining the location of the second mobile communication device based on a signal strength of the short-range radio signal received from the second mobile communication device.

11. The computer-readable storage device of claim 9 , wherein the operations further comprise:

after receiving the short-range radio signal from the second mobile communication device, determining whether an address associated with the short-range radio signal matches identification information stored on a subscriber database of a network; and

in response to determining that the address associated with the short-range radio signal matches identification information stored on the subscriber database of the network, determining that the second mobile communication device emitting the short-range radio signal is a mobile communication device instead of a fixed communication device.

12. The computer-readable storage device of claim 11 , wherein the operations further comprise reporting, along with the location of the second mobile communication device, information indicating that the second mobile communication device is a mobile communication device.

13. The computer-readable storage device of claim 8 , wherein the frequency further depends upon whether the location of the first mobile communication device is static or dynamic.

14. The computer-readable storage device of claim 8 , wherein the second mobile communication device determines the location of the second mobile communication device, detects a presence of the first mobile communication device within a proximity of the second mobile communication device, determines the location of the first mobile communication device, and reports the location of the first mobile communication device and the location of the second mobile communication device.

15. A method comprising:

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

determining, by the first mobile communication device, a location of a second mobile communication device located within a proximity of the first mobile communication device; and

reporting, by the first mobile communication device, the location of the first mobile communication device and the location of the second mobile communication device, wherein at least one of determining the location of the first mobile communication device, determining the location of the second mobile communication device, or reporting the location of the first mobile communication device and the second mobile communication device is repeatedly performed at a frequency, wherein the frequency depends, at least in part, on a characterization of a crowd size associated with the location of the first mobile communication device such that when the location of the first mobile communication device is characterized as being associated with a large crowd size, the frequency is higher than when the location of the first mobile communication device is characterized as being associated with a small crowd size.

16.
