Problems solved by technology

Among them, the method of locating the UE based on the channel fingerprint needs to scan the channel information of each location in advance, and the workload is huge; while the method of locating the UE based on the measurement can not accurately identify the UE and the antenna because multiple antennas can receive the uplink signal of the UE. distance, resulting in inaccurate UE positioning

Abstract

The invention discloses a method, device and system for locating user equipment. The method is applied to a communication system, and the communication system includes a location card, a signal transmission point and a reader, the location card corresponds to the signal transmission point one by one, and the signal corresponding to the location card corresponds to the location card The distance between the transmission points is less than a preset value, and the method includes: the location card detects an uplink signal sent by a user equipment UE; the location card generates a first signal according to the uplink signal, and sends the first signal to to the reader, so that the reader determines the location of the UE according to the first signal and the location of the location card. The method not only simplifies the method for locating the user equipment in the prior art, but also improves the accuracy of locating the UE.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method, device and system for locating user equipment. Background technique [0002] In order to solve the positioning problem of user equipment (UE), especially the indoor positioning of UE, the industry has carried out a lot of research, for example, based on network assisted Global Positioning System (network assisted Global Positioning System), pseudolite (Pseudo-satellite), wireless Research on local area network (WLAN), Bluetooth (Bluetooth, BT) and other positioning technologies. Among these technologies, some are mainly used for navigation and positioning, such as pseudolites; and some are mainly used for providing communication services, but can also provide positioning services, such as WLAN. [0003] In the existing communication system, there are mainly two methods for UE positioning: a method for positioning UE based on channel fingerprints and ...
