Embodiment 1

[0082] Such as figure 1 As shown, in a specific embodiment, the present invention provides a method for obtaining a relative distance based on Wi-Fi, which includes:

[0083] The first terminal sends a distance acquisition request to the second terminal; the first terminal collects terminal information of the first terminal;

[0084] After obtaining the distance obtaining request, the second terminal collects terminal information of the second terminal, and sends the terminal information to the first terminal;

[0085] After the first terminal receives the terminal information sent by the second terminal, it matches it with the terminal information of the first terminal, and calculates the relative relationship between the first terminal and the second terminal according to the matching result. distance;

[0086] The terminal information includes at least: Wi-Fi transmission source information and or mobile base station information collected by the terminal, and time information. Th...

Embodiment 2

[0109] Such as figure 2 As shown, the present invention also provides a terminal that can obtain a relative distance, and the terminal includes:

[0110] The request receiving unit is used to send and / or receive a distance acquisition request;

[0111] A terminal information acquisition unit, configured to acquire terminal information collected by the terminal itself, and receive collected terminal information sent by other terminals;

[0112] The distance acquiring unit is configured to match the terminal information sent by the other terminal by the terminal with the terminal information collected by the terminal itself, and calculate the relationship between the terminal and the other terminal according to the matching result. The relative distance of the terminal;

[0113] The terminal information includes at least: Wi-Fi transmission source information and or mobile base station information collected by the terminal, and time information.

[0114] In a specific implementation, th...

Embodiment 3

[0123] In yet another specific implementation manner, the present invention also provides another method for acquiring the relative distance of a terminal, which includes:

[0124] The first terminal sends a distance acquisition request to the second terminal;

[0125] Collecting terminal information of the first terminal by the first terminal;

[0126] After obtaining the distance obtaining request, the second terminal collects terminal information of the second terminal, and sends the terminal information to the first terminal;

[0127] After receiving the terminal information sent by the second terminal, the first terminal extracts the feature vectors of the terminal information of the first terminal and the second terminal, and obtains the first terminal and the first terminal through a distance calculation function. The relative distance of the two terminals;

[0128] The terminal information includes at least: Wi-Fi transmission source information and or mobile base station infor...

Abstract

The embodiment of the invention discloses a method for acquiring the relative distance of terminals and a terminal, and relates to the technical field of wireless communication. The method may increase distance acquisition precision, reduces manpower and material resource cost, and comprises steps that a first terminal sends a distance acquisition request to a second terminal; the first terminal acquires the terminal information of the first terminal; after acquiring the distance acquisition request, the second terminal acquires the terminal information of the second terminal and sends the terminal information to the first terminal; and after receiving the terminal information sent by the second terminal, the first terminal matches the terminal information with the terminal information of the first terminal, and calculates the relative distance between the first terminal and the second terminal according to a matching result. The method applies to terminal distance acquisition in a Wi-Fi signal field.

Description

Technical field [0001] The present invention relates to the technical field of wireless communication, and belongs to the field of obtaining relative distances between middle ends, and in particular to a method for obtaining relative distances based on Wi-Fi and a terminal device capable of obtaining relative distances. Background technique [0002] In the field of LBS (Location Based Services), many application systems require mobile terminals (such as mobile phone devices) to estimate the approximate distance between users, and then conduct business activities such as making friends and recommending services. Specifically, LBS can be divided into leisure and entertainment, life service, social and commercial. The above-mentioned applications must provide the positioning function of the mobile terminal, and the higher the positioning accuracy, the more convenient the positioning means, and the richer the services that can be provided to users. [0003] Currently, positioning tech...
