Patent ID: 7783296

Claim:
A method for correlating a vehicle with the road on which it travels based on cellular communication, the method comprising the steps of: gathering a sequence of cellular network events related to one or more mobile units, and a physical, geographically-defined, accurate location of each mobile unit determined by a physical geographically-defined, accurate location determination system when each cellular network event occurs, such cellular network events and physical, geographically-defined accurate locations being gathered during one or more drives and then stored as entries in a learnt database as a location reference; and conducting analysis of a new sequence of cellular network events related to a particular mobile unit, the new sequence of cellular network activity events being gathered during a new drive and is independent of physical, geographically-defined location information, in conjunction with the learnt database to correlate the new sequence of cellular network events to a physical geographic location; whereas the new sequence of cellular network events is extrinsically collected from the base stations or the controllers or main switching systems or communication links between them and whereas the new sequence of cellular network events is processed to overcome the problem of similar sequences for neighboring routes and whereas the step of conducting analysis is performed for areas in which at least two roads are covered, at least partially, by the same two or more cells.
