1. A method for transporting residue of vehicle position data via a wireless network, comprising the steps of:

  • receiving, by a processor in a vehicle-mounted terminal in a vehicle, data for updating residue encoding schema from a monitor server via the wireless network;

    calculating, by the processor, a probability of occurrence of a residue of the vehicle in which the vehicle-mounted terminal is located based on a first value and a second value received from the monitor server that characterizes a normal residue distribution of position data of all vehicles complying with a constraint condition;

    constructing, by the processor, a residue encoding schema based on the probability of occurrence of the residue, thereby producing a constructed residue encoding schema;

    storing, by the processor, the constructed residue encoding schema such that the constructed residue encoding schema will become a current residue encoding schema; and

    transmitting, by the processor, codes from the vehicle-mounted terminal in the vehicle to the monitor server using the current residue encoding schema thereby reducing a total length of the codes transmitted via the wireless network;

    wherein;

    the constructed residue encoding schema is constructed such that each residue of the constructed residue encoding schema corresponds to one code; and

    the constructed residue encoding schema is constructed such that a residue having a relatively high probability of occurrence corresponds to a code of relatively short length.
