Abstract

The embodiment of the invention discloses a three-point stereo base station positioning method and device. The method comprises the following steps that preset space coordinate (a, b, H) information in preset coordinates of three base stations of a mobile terminal transmitting signal to be positioned is acquired and received, the preset space coordinate (a, b, H) information comprises the height H of each base station and plane coordinate (a, b) information corresponding to the situation that the base station is located on a plane of which the height H is zero, a distance difference from the three base stations to the mobile terminal to be positioned is acquired according to the preset space coordinate (a, b, H) information of the three base stations is acquired, and position information of the mobile terminal to be positioned according to the distance difference from the three base stations to the mobile terminal to be positioned and a preset positioning equation set. By means of the three-point stereo base station positioning method and device, the problem that positioning error occurs due to the fact that the base station height information is out of consideration when the mobile terminal is positioned based on TDOA positioning technology in the prior art is solved, and positioning accuracy is improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a three-point three-dimensional base station positioning method and device. Background technique [0002] Location based service (LBS), also known as positioning service, refers to the mobile communication network of mobile terminals and operators, such as code division multiple access (Code Division Multiple Access, CDMA) network, Global System for Mobile communication (Global System for Mobile Communications, GSM) network, etc., cooperate with each other, judge the location of the mobile terminal through the base station that transmits the mobile terminal signal, and determine the geographical location information of the mobile terminal user, that is, the longitude and latitude coordinates, so as to provide the location-related service information required by the user . The process of positioning services only takes a few seconds, and the traffic cost is only a few tens of bytes. D...
