Embodiment Construction

[0073] The present invention uses the probe device to simulate the cell search process of the mobile phone to complete the acquisition of the E-CELLID, and then the probe device simulates an LTE base station to induce the UE to reside; in the process of the UE attaching process, the UE is instructed to report the IMSI / IMEI number; After the UE resides in the cell established by the pseudo-base station, the pseudo-base station initiates the establishment of a test loopback link, and then repeatedly instructs the UE to report the received RSRP measurement value. The larger the RSRP value, the closer the distance to the UE. Based on this, the location of the UE is judged.

[0074] After obtaining the E-CellID where the UE is located and the network location area where the UE is located, a detection area can be defined within the cell range. The network location area is an area where the actual base station equipment can cover and provide services, that is, the area of ​​the cell, ...

Abstract

The invention provides a method for positioning a long term evolution (LTE) terminal in a cell range. The method comprises the following steps that: probe equipment simulates the process of searching a mobile phone cell, acquires a cell network identifier (E-CELLID), and simulates an LTE base station to induce user equipment (UE) to reside; when performing an adhesion flow, the UE can be required to report an international mobile subscriber identity/international mobile equipment identity (IMSI/IMEI) by using a message flow which is regulated by a protocol; and after the UE resides a cell which is established by a pseudo base station, the pseudo base station initiates and establishes a test loop link, and repeatedly indicates the UE to report received reference signal received power (RSRP) measurement values, wherein a higher RSRP measurement value indicates a shorter distance between the UE and the cell, so that the position of the UE can be determined. By the method, a device used in the method can be applied under the practical condition that LTE base station equipment is damaged, and the UE can be positioned in a short distance.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a UE (user equipment) positioning within a short distance within a cell range after the cell network identifier (E-CELLID) where the user is located is obtained or known in an LTE mobile communication system techniques and methods. Background technique [0002] The LTE positioning service system generally adopts three positioning methods, namely Assisted Global Navigation Satellite System (A-GNSS, Assisted Global Navigation Satellite System), downlink time difference of arrival and enhanced cell ID. [0003] A-GNSS is a technology that combines network base station information and satellite navigation information to locate mobile stations. [0004] Downlink Time-Observed Difference of Arrival OTDOA is a UE-assisted OTDOA positioning method, and the final position calculation is performed in the calculation center. [0005] The implementation method of e...
