LTE uplink energy measurement method

Abstract

The invention belongs to the technical field of the mobile communication, and discloses an LTE uplink energy measurement method. The method comprises the following steps: detection equipment acquirespublic network information of a public network resided by user equipment through frequency sweeping; the detection equipment and the public network perform air interface synchronization; the detectionequipment acquires public network downlink data to decode PCFICH so as to acquire a CFI value, blindly detects the PDCCH to acquire uplink scheduling information; the detection equipment acquires theuplink data of the uplink scheduling information according to a HARQ mechanism; and the detection equipment measures the uplink energy of the user equipment according to the uplink data. The problemsthat the energy measurement can be started as long as the target user equipment is accessed to a pseudo base station in the existing positioning measurement method, the measurement distance is short,the measurement can be easily sensed by the target user, the volume and the power consumption of the detection equipment are large, and other user equipment can be easily interfered in the process oftracking and positioning the target user equipment are solved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an LTE uplink energy measurement method. Background technique [0002] In recent years, with the vigorous development of LTE technology, LTE terminals have been widely popularized. The complexity of wireless network environment and technology has made it more difficult for public security organs to accurately locate the trapped people in criminal arrests and disasters. [0003] In the existing public security positioning system, it is widely used to establish a pseudo station, make the target user equipment (target UE) reselect into the pseudo station, and then measure the uplink energy of the target UE to achieve tracking and positioning. The disadvantages include: (1) The established pseudo station needs to be on the same frequency as the public network, and the same-frequency interference caused by this will cause great interference to other UEs in the public netw...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an LTE uplink energy measurement method, which is applicable to TDD and FDD. The purpose is to solve the problem that in the existing positioning measurement method, the target UE needs to access the pseudo base station to start the energy measurement. The measurement distance is relatively short, and the measurement is easily perceived by the target user. The volume and power consumption of the detection equipment are large, and it is easy to cause interference to other UEs in the process of tracking and locating the target UE
