Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The invention relates to a positioning method, which is implemented according to the following steps:
step 1, communication is carried out through a first network, and appointed position information is obtained;
the specific process of step 1 is as follows:
receiving target network information inquiry response information fed back by a first network information server; the target network inquiry response information carries first network information.
Step 2, determining a designated area according to the designated position information;
the specific process of the step 2 is as follows:

And 5, measuring the distance according to the round-trip transmission time of the network.
The positioning mode based on the GPS is to utilize a GPS positioning module on the mobile phone to send own position signals to a positioning background to realize the positioning of the mobile phone. The positioning of the base station determines the position of the mobile phone by using the measured distance of the base station to the distance of the mobile phone. The latter does not require the handset to have GPS location capability, but the accuracy depends heavily on the density of base stations, sometimes with errors in excess of one kilometer. The former has higher positioning precision. In addition, a mode of positioning in a small range by utilizing Wifi exists.
The mobile phone positioning system can be divided into two types according to the service providing mode: the system comprises a mobile phone positioning system and public positioning service. Public mobile location services are typically provided by mobile operators. Some positioning systems are self-used by a certain enterprise and government department. It is mainly used for locating people, events, articles, vehicles and the like. The positioning mode is widely used for urban management component positioning, logistics goods and vehicle positioning, long-distance vehicle positioning, emergency rescue positioning and the like. The mobile phone positioning system has the advantages of being more flexible and easier to control. Location systems are often connected to government or enterprise intranets, provide location-based services that are more closely related to their own business, such as personnel attendance, cargo and event location, and can be analyzed and counted geographically using the systems' intelligent analysis tools. These functions are not available with public location services.
The mobile phone positioning system is not necessarily mobile phone GPS positioning, and first, there are two positioning technologies, one is positioning based on GPS, and the other is positioning based on a base station of a mobile operating network. The positioning mode based on the GPS is to utilize a GPS positioning module on the mobile phone to send own position signals to a positioning background to realize the positioning of the mobile phone. The positioning of the base station determines the position of the mobile phone by using the measured distance of the base station to the distance of the mobile phone. The latter does not require the handset to have GPS positioning capability, but the accuracy depends greatly on the distribution of base stations and the size of the coverage area, sometimes with an error of more than one kilometer. The former has higher positioning precision. In addition, a mode of positioning in a small range by utilizing Wifi exists.
The positioning method can position each potential position in the potential multiple positions, thereby ensuring the position to be accurate, enabling a user to quickly position a destination and the position of the user, and further selecting the most suitable route.
