Embodiments of the present invention provide a positioning method and a terminal, which relate to the communication field and can effectively improve the positioning accuracy of the terminal and reduce the cost of base station deployment. The method includes: the terminal acquires the first base station signal, the second base station signal and the third base station signal; the terminal determines the position parameter of the first base station according to the first base station signal, determines the position parameter of the second base station according to the second base station signal, and determines the position parameter of the second base station according to the second base station signal. The three base station signals determine the position parameter of the third base station; the position parameter is the distance between the terminal and the base station corresponding to the position parameter or the angle at which the signal of the base station corresponding to the position parameter arrives at the terminal; the terminal according to the position parameter of the first base station, the second base station The location parameter of the third base station and the location parameter of the third base station determine the location of the terminal. The present invention is used for terminal positioning.
Description
technical field [0001] The present invention relates to the communication field, in particular to a positioning method and a terminal. Background technique [0002] With the continuous development of society and science and technology, terminals have an increasing demand for acquiring location information. Since the terminal works indoors most of the time, applications such as catering, shopping, parking, and medical treatment, as well as some enterprise equipment management, personnel monitoring, and accident rescue and other information management platform applications, all operate in an indoor environment. , so it is more and more important for indoor positioning. [0003] At present, although the terminal can obtain location information through the global satellite positioning and navigation system, since buildings will affect the transmission of satellite signals, the accuracy of the location information obtained through the global satellite positioning and navigation ...
