Abstract:
Embodiments of the disclosure provide methods and systems for determining a position of a terminal device. The system may include a receiving module configured to receive current position information associated with the terminal device, the current position information including one or more positions indicative of the present location of the terminal device. The system may further include an acquisition module configured to acquire historical position information associated with the terminal device, said historical position information being separated from the current position information by a predetermined time interval. The system may further include a determination module configured to determine, based on the historical position information, an actual position of the terminal device from the current position information.
