Abstract

The invention discloses a mobile phone positioning system and a method. The method comprises the following steps that: a base station builds a database of longitudes and latitudes of the coverage area thereof; the base station receives the request of obtaining the position of the current mobile phone sent by a user and sends a distance measuring signal to the mobile phone, determines the distance between the mobile phone and the base station per ser according to the data stored in the database and the round-trip time of the distance measuring signal, further determines the longitude and latitude range of the mobile phone, sends the information of the longitude and latitude range of the mobile phone into the server to which the base station belongs; and the server computes the precise position of the mobile phone and sends the information of the precise position of the mobile phone into the mobile phone of the mobile phone user by the base station in the range thereof according to the information of the longitude and latitude range of the mobile phone which is received from the base station. The invention can realize the precision positioning of the mobile phone and has small expenditure and shorter positioning time.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a mobile phone positioning system and method. Background technique [0002] At present, most people use the Global Positioning System (GPS) to achieve global positioning. The so-called GPS refers to the use of 24 artificial satellites that run on six orbits about 20,000 kilometers above the ground. The position of the signal receiver on the earth is calculated by the principle of triangulation. With the GPS receiver on the ground, the satellite signal can be received to calculate the correct position. [0003] In recent years, with the advancement of the electronics industry and the maturity of GPS technology, GPS technology has been widely used in business and consumer life. Consumer electronic products such as Global System for Mobile Communication (GSM) mobile phones have been launched one after another. It is not only thin and small in size, but also cheap in price, m...
