Embodiment Construction

[0054] In order to make the above-mentioned features and advantages of the present invention more comprehensible, preferred embodiments will be described in detail below together with the accompanying drawings.

[0055] The general positioning algorithm does not take the surrounding environmental factors into account when it is actually applied, which makes the error range of positioning quite large. Therefore, in order to improve the accuracy of positioning, the present invention proposes a positioning method for a portable communication device that utilizes regional features to correct positioning coordinates. In order to make the content of the present invention clearer, the following specific examples are given as examples in which the present invention can actually be implemented.

[0056] figure 1 is a block diagram of a positioning system according to an embodiment of the present invention. Please refer to figure 1 , the positioning system 100 includes base stations ...

Abstract

A method for positioning a portable communication device, which adopts a server device to position the portable communication device, comprises the following steps: firstly, the server device receives the identification data and the signal intensity of a base station, which is detected by the portable communication device; the server device determines the regional characteristics of the region, in which the portable communication device is currently positioned, based on the identification data and the signal intensity of the base station; and then, the server device calculates the positioning coordinate, at which the portable communication device is positioned, and regulates the positioning coordinate based on the regional characteristics, thereby greatly improving the positioning accuracy.

Description

technical field [0001] The present invention relates to a positioning method, and in particular to a method for correcting the positioning coordinates of a portable communication device by utilizing the regional characteristics of the area where the portable communication device is located. Background technique [0002] Location Based Service (LBS) is to obtain the user's location information (for example, longitude and latitude or the geographical environment of the local street, etc.) ), or other organizations and individuals requesting the user's location. Due to the low-cost, high-precision and easy-to-popularity of using the mobile device itself for positioning, in recent years, the positioning service of mobile devices has been widely used in emergency rescue, car navigation, intelligent transportation, team management, etc., and has become the current One of the most notable developments. [0003] Generally speaking, if the error caused by the propagation environmen...
