Problems solved by technology

[0004] When using method (1), if the terminal device is not equipped with GPS, the location of the terminal device cannot be determined; and GPS can only have signals in open areas. For areas where GPS signals cannot be received (such as indoors, under elevated roads, etc.), will not be able to determine the location of the end device
When using method (2), joint participation of multiple base station devices is required, the algorithm is relatively complex, and signaling interaction and synchronization between base station devices are required, resulting in high overhead

Abstract

The invention discloses a method and device for determining the position of a terminal. The method comprises the following steps that: a base station device acquires distance information between a terminal device and the base station device through the timing advance (TA) of the terminal device; the base station device acquires direction information between the terminal device and the base station device through the measurement level information of the terminal device; and the base station device determines the position information of the terminal device according to the distance information and the direction information. In the embodiment of the invention, the positioning of the terminal device can be realized without the help of a GPS (global position system) or signaling interaction and synchronization between base station devices, and the position of the terminal device can be determined through a single base station device, thereby simplifying the positioning algorithm of the terminal device, reducing the signaling interaction overhead between the base station devices and improving the positioning efficiency of the terminal device.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for determining a terminal location. Background technique [0002] In the prior art, in order to locate the terminal device, the following methods can be adopted: (1) Install a GPS (Global Positioning System, Global Positioning System) in the terminal device, and the terminal device obtains its own position through the GPS, and The obtained position is reported to the base station equipment, so that the base station equipment determines the position of the terminal equipment. (2) Multi-base station joint positioning, that is, through signaling interaction between multiple base station devices, the location of the terminal device is finally determined. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] When using method (1), if the terminal d...
