First Claim
1. A method for positioning user equipment (UE), the method being applied to a communications system, the communications system comprising a location card and a reader, and the method comprising:
- detecting, by the location card, an uplink signal from the UE;
generating, by the location card, a first signal according to the uplink signal, the first signal comprising a pulse signal having an amplitude, the amplitude of the pulse signal being based on a preset proportional relationship with a strength of the uplink signal, the amplitude of the pulse signal being increased when the strength of the uplink signal increases, and the amplitude of the pulse signal being decreased when the strength of the uplink signal decreases;
sending, by the location card, the first signal to the reader, the first signal carrying identification information of the location card, and the first signal instructing the reader to determine a location of the UI according to the identification information of the location card, the amplitude of the pulse signal, and a location of the location card; and
sending, by the reader, a notification message to a network side device to adjust a transmit power of the UE based on a number of location cards that detect the uplink signal from the UE, the notification message being used to increase the transmit poser of the UE when the number of location cards that detect the uplink signal from the UE is less than a preset first threshold, and the notification message being used to decrease the transmit power of the UE when the number of location cards that detect the uplink signal from the UE is greater than a preset second threshold.

Abstract
A method, device and system for positioning user equipment (UE). The method is applied to a communications system including a location card, a signal transmitter and a reader. The location card and the signal transmitter are in a one-to-one correspondence, a distance between the location card and the signal transmitter corresponding to the location card is less than a preset value, and the method includes detecting, by the location card, an uplink signal sent by UE, and generating, by the location card, a first signal according to the uplink signal, and sending the first signal to the reader such that the reader determines a location of the UE according to the first signal and a location of the location card. The method not only simplifies a method for positioning UE in other approaches, but also improves accuracy of UE positioning.
