Embodiment Construction

[0033] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that when assigning reference signs to constituent elements in each figure, the same constituent elements should be given the same symbols as much as possible even if they are marked on different drawings. In addition, in describing the present invention, when it is judged that a specific description of a well-known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

[0034] In this specification, a wireless communication system means a system for providing various communication services such as voice, packet data, and the like. A wireless communication system includes a user terminal (User Equipment, UE) and a base station (Base Station, BS).

[0035] A user terminal is a general concept referring to a terminal in wireless communication, and should be interpreted as n...

Abstract

Provided are a location measurement device and a location measurement method thereof, wherein the location measurement device receives an uplink signal from at least one target terminal which is subject to measuring a location or determining existence or nonexistence, and variably sets an uplink search time window of the uplink signal received from the target terminal according to at least one or two of a location of the location measurement device, a location of a base station, a cell radius of the base station, a distance from the base station, a range of location at which the target terminal is predicted to exist, and a signal detection range in which the uplink signal is detected from the target terminal.

Description

technical field [0001] The present embodiment relates to a method and apparatus for measuring the location of a target terminal using a wireless communication system. Background technique [0002] Recently, for public services, there have been attempts by third parties other than communication service providers to acquire position or movement information of terminals existing in a specific area. For example, public organizations of the Korea Expressway Corporation and the National Police Agency try to obtain information such as the number or speed of terminals passing through a specific area. [0003] In this case, a third party other than the communication service provider cannot obtain information on the positions or traffic of terminals existing in a specific area for public services. In particular, there are limitations in implementing methods of obtaining such information without affecting existing communication devices and communication networks. In addition, it is n...
