Embodiment Construction

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] At present, there are two shortcomings in the 4G positioning process. One is that the adsorption distance is relatively short and the target is easily disconnected during the movement process due to the same-frequency interference of the public network. Authentication also includes authentication of the terminal by the network. The terminal cannot register in the...

Abstract

The embodiment of the invention provides a redirection positioning method and device. The method includes the following steps: adsorbing a target terminal to reside in a same-frequency 4G positioningcell, wherein the same-frequency 4G positioning cell is established according to the frequency point of a resident cell of the target terminal; sending a redirection message to the target terminal toensure that the target terminal is redirected from the same-frequency 4G positioning cell to a GSM positioning cell according to the redirection message, wherein the GSM positioning cell is established according to an absolute radio frequency channel number (ARFCN) of a GSM cell without a public network; and carrying out positioning in the GSM positioning cell. According to the redirection positioning method and device provided by the embodiment of the invention, the same-frequency 4G positioning cell and the GSM positioning cell are established, and the target terminal is redirected to the GSM positioning cell, so that the target terminal can be positioned more stably and reliably by using the characteristic that the GSM positioning cell has no public network interference and low narrow-band system frequency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular, to a redirection positioning method and device. Background technique [0002] In the past two years, the fourth-generation mobile communication 4G has become the mainstream technology of mobile communication, and the positioning technology has also been upgraded from the detection and positioning system originally based on the second-generation mobile communication 2G and the third-generation mobile communication 3G to 4G active positioning technology. The traditional 4G positioning process is as follows: 1. The mobile phone stays on the public network; 2. Initiates a tracking area update TAU to enter the positioning cell; 3. The positioning cell periodically updates the tracking area code TAC in the broadcast information, and guides the mobile phone to initiate TAU access positioning again cell; 4. Repeat steps 2 and 3 to locate the target b...
