Problems solved by technology

[0021] 1) When using GPSOne to track the location, it is difficult to track the location because the GPS satellite signal inside the building and underground becomes very weak
[0022] 2) Therefore, GPSOne technology says that when it is difficult to track the location inside the building, it can measure the electric field strength of the base station near the mobile communication terminal and use triangulation to track it, but this function is not currently used
Moreover, even if this function is used, the error range (about 100M) is relatively large
[0023] As mentioned above, GPSOne has not been widely used by users due to the difficulty of tracking location inside buildings with existing technology, and the margin of error becomes larger without the use of triangulation methods

Embodiment Construction

[0033] An embodiment of the location tracking method for a mobile communication terminal of the present invention will be described below with reference to the accompanying drawings.

[0034] figure 2It is a flow chart of the mobile communication terminal position tracking method of the present invention.

[0035] As shown in the figure, it includes 3 stages. In the first step (steps ST1, ST2), the mobile communication terminal 10 connects to the positioning server 60 with a browser and inquires about the position through the data network. At this time, the above-mentioned positioning server 60 will send the above-mentioned Mobile communication terminal 10 sends GPS tracking request; In second step (step ST3, ST4), above-mentioned mobile communication terminal 10 connects GPS receiver 30 and requires to obtain satellite receiving data, then above-mentioned GPS receiver 30 will send to above-mentioned mobile communication terminal 10 deliver the data that receives from satell...

Abstract

The present invention discloses a method for location trace of mobile communication terminal. It comprises 3 steps, in the first step mobile communication terminal connects to the orientation server by browser and inquires location by data net, here the said orientation server will transmit global positioning system trace demand to the said mobile communication terminal; in the second step, the said mobile communication terminal connects with global positioning system receiver and speaks for satellite receiving data, then the said global positioning system receiver will transfer the data received from satellite to the said mobile communication terminal; in the third step, mobile communication terminal transfers the received satellite data to the said orientation server, then the said orientation server will transfer map information containing position to the said mobile communication terminal. Through the said method, the present invention can process location trace in limitative space such as building and in terminal with location trace function.

Description

technical field [0001] The invention relates to a location tracking method for a mobile communication terminal, in particular to a location tracking method for a mobile communication terminal that can track the location of a terminal with a location tracking function in a limited space such as inside a building. Background technique [0002] The mobile communication system is generally a communication system for moving objects such as people, automobiles, ships, trains, and aircrafts, including keypad telephone systems, mobile phones (portable phones, vehicle phones), harbor phones, aircraft phones, and mobile public phones.
