Abstract
A plurality of vehicle identity collection modules are deployed at different toll collecting locations, wherein each vehicle identity collection module is configured to broadcast wireless communication signals to cover a mobile communication device associated with a vehicle passing by the toll collection location over a wireless communication network, wherein strength of the signals is maximized so that mobile communication device switches and connects with the vehicle identity collection module during a wireless cell re-selection process. A mobile communication channel is then established and identification information of one or more of the vehicle, the driver, and the mobile communication device is retrieved via the mobile communication channel. Based on the retrieved information, actual moving path of the vehicle from its initial toll collecting location where the vehicle is first sensed to its current toll collecting location where the vehicle is last sensed is generated and a toll amount is calculated accordingly.
