Problems solved by technology

[0011] To sum up, some 2G, 3G, 4G, 5G, and NB-IoT network mobile terminals in indoor scenarios can locate the building or its vicinity, but cannot locate floors and rooms; the rest of the mobile terminals cannot accurately locate the building
Therefore, it is difficult to search for mobile terminal users in emergency situations

Abstract

The invention discloses a method and a device for determining the distance of a mobile terminal based on a comparison feature Wi-Fi list. The method comprises the following steps: acquiring the feature Wi-Fi list; the feature Wi-Fi list is collected by a first mobile terminal; the characteristic Wi-Fi list comprises surrounding Wi-Fi information and target Wi-Fi information; acquiring an on-site Wi-Fi (Wireless Fidelity) list; the field Wi-Fi list is collected by a second mobile terminal; comparing the field Wi-Fi list with the characteristic Wi-Fi list; the comparison result or the distance information is prompted; wherein the distance information is determined according to the comparison result; the method for determining the distance information comprises the following steps of: 1, judging the distance information according to the number of the same Wi-Fi; the second method comprises the following steps: judging the distance information through the signal intensity of the key Wi-Fi; according to the third method, the distance information is judged according to the signal strength of the target Wi-Fi.

Description

technical field [0001] The present invention relates to the field of search, in particular to a method and device for determining the distance of a mobile terminal based on a Wi-Fi list of comparative features. Background technique [0002] The satellite positioning accuracy is high, and the error range is about 10 meters. Due to the occlusion of steel bars and cement, satellite signals cannot be received indoors in most cases, so indoor satellite positioning cannot be used in most cases. [0003] The error range of Wi-Fi positioning is 40-300 meters. Wi-Fi positioning relies heavily on databases, requiring location service providers to continuously update the database, resulting in a huge workload. Wi-Fi that has been marked also sometimes moves, making the location marking out of date. Wi-Fi positioning generally has the following results: successful positioning, incorrect coordinates returned, and positioning failure. [0004] There are two cases for base station posi...
