Determining path traversed by a mobile communication device |
| 摘要 |
The invention provides a method and system for determining path traversed by a mobile communication device in an unobtrusive manner. The method involves providing a tower transition data involving identifying a set of GPS coordinates associated with a cellular network tower ID, and identifying the tail GPS coordinate and head GPS coordinate of consecutive cellular network tower IDs. Then the distance between the tail and head is estimated, based on which the sequence of cellular network tower IDs are determined, which provides the path traversed by the mobile communication device. |

1. A method for determining a path traversed by a mobile communication device, the method comprising:
providing a tower transition data; receiving at least two cellular network tower IDs sequentially; identifying at least one head GPS coordinate and at least one tail GPS coordinate associated with each transition between two consecutive cellular network tower IDs from the tower transition data; estimating a distance between each tail GPS coordinate and each head GPS coordinate between two consecutive transitions; and selecting at least one most probable transition associated with a minimum distance between two consecutive transitions; and determining the path traversed by the mobile communication device based on the at least one most probable transition. |
