Terminal positioning method and device in LTE tracking area range

Abstract

The invention provides a terminal positioning method and device in an LTE tracking area range, and the method comprises the steps: carrying out the frequency sweeping and system message analysis of all frequency points in a tracking area, and determining the sending time of a paging message and the prior information of a preset simulation base station; triggering a paging process for multiple times, analyzing the paging process, and determining a temporary mobile user identification code of the target terminal through multiple times of paging message content collision; based on each preset simulation cell, obtaining a temporary mobile user identification code of each terminal accessed to the simulation cell; and matching the temporary mobile user identification code of the target terminalwith the temporary mobile user identification code of each terminal accessing the simulation cell, and determining the target simulation cell to which the target terminal is attached so as to accurately position the target terminal. The temporary mobile user identification code of the terminal acquired by establishing the simulation cell is matched with the temporary mobile user identification code of the target terminal acquired by identity collision, so that the target terminal can be accurately positioned under the condition that the IMSI of the target terminal is unknown.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a terminal positioning method and device within the range of an LTE tracking area. Background technique [0002] With the development and wide application of the LTE technology, the related small base station technology also emerges as the times require, and positioning the target terminal is an important branch of the current small base station application. [0003] The mainstream positioning technology of the current LTE system is carried out on the premise that the International Mobile Subscriber Identity (IMSI) of the target terminal is known. The IMSI of the terminal in the current network environment is obtained through a certain method, and compared with the IMSI of the target terminal. Initially determine the location of the target terminal. [0004] However, the methods in the prior art must know the IMSI of the target to complete the positioning, a...

Problems solved by technology

[0004] However, the methods in the prior art must know the IMSI of the target to complete the positioning, and the IMSI needs to coordinate the resources of all parties to obtain the IMSI in practical applications. During this process, the target terminal may leave the tracking area and miss the best time to locate the target terminal. Timing, it is foreseeable that in the case of limited time, the IMSI must be known to locate certain limitations
