Problems solved by technology

[0004] However, the above solutions usually use a fixed formula to calculate the distance. When the terminal is blocked by obstacles, the degree of signal attenuation increases, and because obstacles are unpredictable, the error in estimating the distance based on the degree of signal attenuation will increase, which will seriously affect the positioning accuracy.

Abstract

The invention provides a terminal positioning method, system and device and a positioning server, and relates to the technical field of communication. The method comprises the steps of obtaining a receiving power value of at least one reference signal of a to-be-positioned terminal, calculating an estimated distance value between the to-be-positioned terminal and at least one base station, calculating an ideal receiving power value of the at least one reference signal according to the estimated distance value, and correcting the receiving power value according to the ideal receiving power value, and correcting the estimated distance value according to the corrected receiving power value to obtain a final distance value of the to-be-positioned terminal. According to the invention, the terminal positioning precision can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a terminal positioning method, system, device and positioning server. Background technique [0002] With the development of communication services, positioning services play an important role as an indispensable part of mobile communication or personal communication services. [0003] In an existing terminal positioning method, the distance between the base station and the terminal can be calculated by measuring the attenuation degree of the positioning reference signal between the base station and the terminal. [0004] However, the above solutions usually use a fixed formula to calculate the distance. When the terminal is blocked by an obstacle, the signal attenuation degree increases, and because the obstacle is unpredictable, the error in calculating the distance according to the attenuation degree of the signal will increase, which will seriously affect...
