US 2017/0013522 A1 · DETERMINING A LOCATION OF A MOBILE DEVICE

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.

Dependent claims

A method for determining a location of a mobile device, comprising:

analyzing call data records of the mobile device to determine a first cell where the mobile device resided and time which the mobile device spent in moving from the first cell to a second cell;
determining probability densities that the mobile device was located at respective locations within the first cell, based on a moving speed of the mobile device and the time;
and
determining possible locations of the mobile device within the first cell, according to the probability densities.
