Abstract

The invention discloses a positioning method for transmitting positioning data across systems, which comprises the following steps that: a mobile terminal is connected with a WLAN access network, acquires an IP address and sends the IP address of the mobile terminal to an initial position computing server; the initial position computing server sends a query request to the WLAN access network, wherein the query request carries the IP address of the mobile terminal; the WLAN access network returns the position information of the mobile terminal to the initial position computing server; the initial position computing server returns the initial position information to the mobile terminal; the mobile terminal sends a positioning query request to a positioning engine, wherein the query request carries the initial position of the mobile terminal in the WLAN access network and peripheral geomagnetic information acquired by the mobile terminal; and the positioning engine returns positioning navigation data to the mobile terminal, wherein the positioning navigation data comprises mobile terminal position coordinates. The invention also discloses a positioning method for transmitting positioning data across systems. Accurate positioning and navigation information in an indoor environment is quickly provided for a mobile terminal user.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to a positioning method and system for transmitting positioning data across systems. Background technique [0002] Mobile terminals, including mobile phones and wearable devices, are commonly used communication and auxiliary tools for people, and most of them realize the function of locating the user's location. The positioning function not only enables the user to know where he is at any time, which is convenient for planning the route, but also enables the device connected to the mobile terminal to query the current position of the user at any time. Existing mobile terminal positioning technologies mainly include WLAN (Wireless Local Area Network) network positioning, Bluetooth beacon positioning, UWB (Ultra-WideBand, ultra-wideband technology) positioning and geomagnetic positioning. [0003] Among them, WLAN network positioning is mainly used in indoor positi...
