Abstract:
1. A method for transporting residue of vehicle position data via a wireless network, comprising the steps of: receiving, by a processor in a backend server, code from a vehicle-mounted terminal via the wireless network; deriving, by the processor, position data of a vehicle from the code according to a current residue encoding schema; determining, by the processor, whether updating the current residue encoding schema is needed according to context information of the vehicle; generating, by the processor, data for updating the current residue encoding schema if updating the current residue encoding schema is needed; transporting, by the processor, the data for updating the current residue encoding schema to the vehicle-mounted terminal via the wireless network if updating the current residue encoding schema is needed; constructing, by the processor, a residue encoding schema based on the data for updating the current residue encoding schema, thereby producing a constructed residue encoding schema if updating the current residue encoding schema is needed; and updating, by the processor, the current residue encoding schema with the constructed residue encoding schema if updating the current residue encoding schema is needed; wherein: the code is code for residue of position data of the vehicle obtained via the vehicle's data acquisition device; the vehicle-mounted terminal is located in the vehicle; the current residue encoding schema corresponds to the vehicle; 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.
