Abstract: Disclosed is a method for increasing location estimation accuracy of a communication device, including identifying a set including at least one sample among a plurality of samples of a probability distribution for estimated locations of the communication device, and determining a location of the communication device among the at least one sample based on a reliability of each of the at least one sample, by determining the reliability of each of the at least one sample in the set, when a difference between a first location of the communication device which is estimated based on a first scheme and a second location of the communication device which is estimated based on a second scheme is greater than or equal to a preset threshold value, and determining a sample of which a reliability is greatest among the at least one sample as the location of the communication device.

Abstract: Apparatuses, systems, and methods for estimating a location of a communication device in an internal environment are described. In one method, a number of movement units made while a mobile terminal moves from a first location to a second location is detected and the location of the mobile terminal is estimated based on the number of detected movement units and a location interpolation scheme.
