Problems solved by technology

In case the terminal is in certain handover areas, it is possible to receive signals from about two base stations and measure a more precise position based on them, but this has the disadvantage of being limited to certain terminals
[0006] Also, when there is an obstacle such as a building between the base station and the terminal, the propagation delay and attenuation may appear much larger than when there is no obstacle, reducing accuracy

Abstract

Disclosed are a position finder, a position measurement server, and a position measurement system capable of estimating a relatively accurate position on the basis of a signal transmitted from a terminal in a mobile communication system. Particularly, the position finder acquires channel configuration information of an uplink signal of a target terminal, receives the uplink signal of the target terminal through one or more uplink signal reception units on the basis of the channel configuration information, measures information on the received uplink signal, and transmits the information on theuplink signal of the target terminal to the position measurement server, and the position measurement server receives the information on the uplink signal of the target terminal from the position finder and calculates a position of the target terminal on the basis of the information on the uplink signal of the target terminal.

Description

technical field [0001] The present disclosure relates to a system for estimating the position of a mobile terminal in a mobile communication system. Background technique [0002] exist figure 1 A general connection between a terminal and a base station in a mobile communication system is shown in . refer to figure 1 , the mobile communication system includes a base station and a terminal. Conventional terminal location estimation methods estimate the locations of corresponding terminals based on signals transmitted from the terminals. In this case, a commonly used method is to use the delay value of the signal required for the signal sent by the terminal to reach the base station. In addition, the distance between the base station and the terminal can be estimated based on the amount of propagation attenuation occurring in a channel through which a signal transmitted by the terminal reaches the base station. [0003] In other words, in a conventional method for estimati...
