Problems solved by technology

However, if the external signal is not ideal, or if there is no external wide area network support, the search and rescue team will have no way to locate the missing person. They can only speed up the search by increasing the number of search and rescue personnel, but this method is limited by the darkness of the night. Restricted, it cannot be deployed at night, resulting in a waste of precious rescue time

Abstract

The invention discloses a mobile terminal positioning method, equipment and system. The method comprises the following steps that a first type mobile terminal sends a first message to a second type mobile terminal, the first type mobile terminal receives a second message returned by the second type mobile terminal, and the second message carries the WIFI (wireless fidelity) signal intensity information PM_Qs of the second type mobile terminal; the first type mobile terminal sends a third message to a center processor, and the third message carries the WIFI signal intensity information PM_Qs, the WIFI signal intensity information R_Qs of the first type mobile terminal and the receiving signal intensity information PM_Qr when the first type mobile terminal receives the information of the second type mobile terminal; the center processor uses the WIFI signal intensity information PM_Qs, the WIFI signal intensity information R_Qs and the receiving signal intensity information PM_Qr for positioning the second type mobile terminal. In the embodiment, the method, the equipment and the system can help searching personnel to automatically and fast position a searched object in a certain range, the searching and rescue efficiency is improved, and the method, the equipment and the system can be used in the fields of outdoor searching and rescue, emergency dealing and the like.

Description

technical field [0001] The present invention relates to the communication field, in particular to a positioning method, device and system for a mobile terminal. Background technique [0002] At present, there are more and more people who like outdoor adventure travel, and incidents of missing and getting lost in tourist areas often occur. Under normal circumstances, search and rescue teams will use GPRS (General Packet Radio Service) to locate way to search for missing persons. However, if the external signal is not ideal, or if there is no external wide area network support, the search and rescue team will have no way to locate the missing person. They can only speed up the search by increasing the number of search and rescue personnel, but this method is limited by the darkness of the night. Restricted, it cannot be deployed at night, resulting in a waste of precious rescue time. Contents of the invention [0003] Embodiments of the present invention provide a position...
