Communication signal detection positioning method and device

Abstract

The embodiment of the invention provides a communication signal detecting and positioning method, which comprises the following steps of: moving a first base station and a detecting and positioning device to an area where to-be-positioned communication equipment is located, performing frequency sweeping by the detecting and positioning device, and acquiring a frequency point to which the to-be-positioned communication equipment is to be switched according to a frequency sweeping result; accessing to-be-positioned communication equipment through a first base station, establishing a pilot frequency cell according to a frequency point to which the to-be-positioned communication equipment is to be switched, and switching the to-be-positioned communication equipment to the pilot frequency cell;the detection positioning device communicates with the to-be-positioned communication equipment to obtain an energy value fed back by the to-be-positioned communication equipment, and the direction and the position of the to-be-positioned communication equipment are determined according to the energy value fed back by the to-be-positioned communication equipment. According to the embodiment of the invention, the to-be-positioned communication equipment stably resides in the pilot frequency cell, so that the detection positioning device stably communicates with the to-be-positioned communication equipment, and accurate positioning of the to-be-positioned communication equipment is realized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a communication signal detection and positioning method and device.
