Problems solved by technology

[0003] However, through the mobile terminal GPS hardware module, it is mainly limited by the need for user participation and the need to open the hardware module
However, the traditional three-point positioning method to achieve user positioning is affected by wireless signal propagation changes (such as non-line-of-sight propagation, multipath, interference, etc.), and the positioning accuracy is poor.

Abstract

The invention discloses a positioning method and a terminal and relates to the field of mobile communication. The positioning method comprises the steps of collecting data information of a plurality of cells in a preset time period, wherein the data information of each cell comprises RSRP (Reference Signal Received Power), an SINR (Signal to Interference plus Noise Ratio) and a CI (Cellular Identity); and carrying out calculation to obtain target longitude and latitude information according to the data information of the plurality of cells, wherein the plurality of cells comprise a master cell and adjacent cells. According to the method and the terminal, the data information of the plurality of cells is collected, the data information of each cell comprises the RSRP, the SINRs and the CIs, the target longitude and latitude information is obtained through calculation, and the positioning precision can be effectively improved. Through adoption of a big data method, an algorithm model is trained, so adjustment factors of different application scenes are optimized, a light positioning platform function is realized, and relatively good convenience and technical feasibility are achieved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a positioning method and a terminal. Background technique [0002] At present, the relevant technologies for positioning mobile network users generally use the GPS (Global Positioning System, Global Positioning System) module in the mobile terminal hardware to collect the corresponding latitude and longitude information through the client mode or the three-point positioning technology through wireless transmission, that is, TOA (Time of Arrival, time of arrival) / TDOA (Time Difference of Arrival, time difference of arrival) technology. [0003] However, the GPS hardware module of the mobile terminal is mainly limited by the need for user participation and the need to open the hardware module. However, the traditional three-point positioning method to realize user positioning is affected by wireless signal propagation changes (such as non-line-of-sight propagation, multipath, i...
