The method includes obtaining a set of points associated with the route, the set of points being obtained by at least one entity travelling along the route. A plurality of coverage areas covering a part of points in the set of points is determined. The coverage areas are connected based on main directions of the coverage areas to obtain the trajectory pattern related to the route. The main directions represent forward directions of the route in respective coverage areas. A corresponding system for obtaining a trajectory pattern of a route is described as well.

  • Publication number: 20160021637
    Abstract: A method and an apparatus for determining a location of a mobile device. The location of a mobile device is determined accurately according to information which includes call data records of the mobile device. By employing a partial ellipse integral model, two physical world factors are taken into consideration in reducing the location uncertainty in call data records. The factors include: spatiotemporal constraints of the device's movement in the physical world and the telecommunication cell area's geometry information, which increase the accuracy of determining the location of a mobile device.
