Problems solved by technology

[0007] (1) The first method is to calculate the distance after obtaining the longitude and latitude of the terminal through positioning technology to determine whether it is adjacent. When the terminal cannot be positioned (such as indoor environment) or the positioning accuracy is not high (such as base station positioning), it will not be poss

Abstract

The invention discloses an adjacent terminal discovery method and device, a terminal and a server, and relates to the technical field of mobile internet. The method comprises the following steps: a base station fingerprint and/or a WIFI fingerprint acquired by a terminal is received; the adjacent level of the terminal is calculated according to the base station fingerprint and/or the WIFI fingerprint acquired by the terminal; and the terminal is judged whether to be an adjacent terminal according to the adjacent level of the terminal and a preset threshold. The scheme aims at the existing problem that the terminal specific position cannot be acquired or the existing problem that the adjacent terminal discovery process cannot be performed because the terminal is not provided with a short distance wireless communication technical module, the method for discovering the adjacent terminal with the base station fingerprint and the WIFI fingerprint acquired by the terminal is provided, so the adjacent terminal can be discovered conveniently.

Description

technical field [0001] The present invention relates to the technical field of mobile Internet, in particular to a method, device, terminal and server for discovering adjacent terminals. Background technique [0002] In the era of mobile Internet, for the consideration of information sharing and security, people often need to know which other terminals are adjacent to a terminal. For example, share contacts, text messages, pictures, videos, etc. in the mobile phone with friends; travel with children, in order to prevent the children from getting lost in the vast crowd, it is necessary to frequently locate whether the children are by their side, etc. These applications all need to use the adjacent terminal discovery technology. [0003] The current technologies for realizing proximity terminal discovery include: [0004] (1) After obtaining the longitude and latitude of the terminal through positioning technology (such as GPS (Global Positioning System, Global Positioning S...
