Embodiment Construction

[0033] In this embodiment of the present invention, statistics are made in advance on the historical record data (which may include location information uploaded by the terminal, data of location information, etc.) Activity rules in the first area within a certain period of time, so as to determine the corrected position information of the first area, so that when the terminal to be positioned in the first area is positioned, the reference position information of the first area can be calculated according to the corrected position information Correction processing is performed to effectively improve the positioning accuracy of the terminal to be positioned.

[0034] The main realization principles, specific implementation modes and corresponding beneficial effects that can be achieved of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0035] The embodiment of the present inve...

Abstract

The invention discloses a terminal location method and a terminal location device based on a cell identifier location technology for solving the low location precision problem of a cell-ID location technology and an improved technology thereof provided in the prior art. The method comprises the following steps of: acquiring an identifier of a first area where a terminal to be located is positioned currently; determining the reference position information and the modified position information of the first area corresponding to the identifier of the first area from the corresponding relation ofthe pre-stored identifier of the first area, the reference position information of the first area, and the modified position information of the first area, according to the identifier; wherein the modified position information is determined based on the pre-counted historical recording data of the terminal appeared in the first area before; and determining the position information of the terminalto be located according to the determined reference position information and the modified position information.

Description

technical field [0001] The present invention relates to the field of computer and communication technologies, in particular to a terminal positioning method and device based on a cell identification positioning technology. Background technique [0002] Cell ID (Cell-ID) positioning technology is the most simple and direct positioning technology in the wireless cellular network at present. The location information of the base station to determine the location information of the terminal to be located, that is, the network side estimates the location range of the terminal based on the location information of the serving base station of the terminal and the size of the cell covered by the serving base station. For example, if the cell in the network If it is an omni-directional cell, the location of the terminal should be located within the entire circle centered on the serving base station and the radius is the coverage radius of the cell. In this case, the location informatio...
