Mobile phone navigation method based on map and social tool

Abstract

The invention discloses a mobile phone navigation method based on a map and a social tool. The method comprises steps as follows: 1) a mobile phone A sends a navigation application to a mobile phone B; 2) the mobile phone B receives the application of the mobile phone A and rejects or agrees the application; 3) the mobile phone B sends rejection information to the mobile phone A, and navigation ends; the mobile phone B agrees the application and sends position information to the mobile phone A; 4) the mobile phone A receives the information sent from the mobile phone B and sends own information to the mobile phone B; 5) the mobile phone B receives the position information from the mobile phone A; 6) the mobile phones A / B read the position information and display the information on the mobile phones; 7) the position of the mobile phone of the opposite side is calculated, and a corresponding navigation route is drawn; 8) the mobile phone A and the mobile phone B send own information to the mobile phone of the opposite side and receive information of the opposite side; 9) the mobile phone A and the mobile phone B refresh the maps, so that the positions of the mobile phone A and the mobile phone B change constantly. According to the method, mobile navigation from a moving point to a moving point can be realized on the basis of the social tool and map software.

Description

technical field [0001] The invention belongs to the field of mobile phone navigation, and relates to a mobile phone navigation method based on maps and social tools. technical background [0002] Mobile phone navigation is to take you from the current place to another place you want to reach by navigating the navigation function of the mobile phone. Mobile phone navigation is satellite mobile phone navigation. The difference between it and the mobile phone electronic map is that it can tell you where you are on the map, as well as the location of the place you are going to on the map, and can tell you where you are and where you are going. Choose the best route between them, and prompt you to turn left or right during the journey, this is the so-called navigation. [0003] As more and more navigation software is available for smartphones with large displays, Portable Navigation Devices (PNDs) are in jeopardy as stand-alone, dedicated devices. Smartphones have had a huge im...

Problems solved by technology

[0004] Now the mobile phone navigation on the market is divided into three categories. The first category is real GPS navigation through satellites in space, with an accuracy of 3-5 meters, such as the navigation of Tianjun T60 mobile phone; the second category is through the base station network. Rough navigation is called CELLID navigation. This kind of navigation is not as accurate as satellite GPS navigation. The general positioning error is 100 meters. For example, China's mobile phone navigation uses this technology for indoor positioning; the third category is AGPS+CELLID+GPS positioning, this kind of navigation is the most accurate, the default is CELLID positioning indoors, first use AGPS to search the star map outdoors to achieve fast positioning, and then automatically switch to GPS high-precision positioning and navigation, such as in China Mobile phone navigation uses this technology
