Embodiment 1

[0071] Such as figure 1 As shown, the embodiment of the present invention provides a method for obtaining terminal location information, including:

[0072] Step 101: The user terminal obtains link information, where the link information includes at least the identity of the terminal, the identity of the data reader, and the identity of the ad-hoc gateway node;

[0073] Step 102: The user terminal establishes a logical link with the terminal according to the link information, and sends its own identity to the terminal through the established logical link;

[0074] Step 103: The terminal receives the identity of the user end, determines the location information with corresponding accuracy according to the identity of the user end, and sends the location information to the user end through the established logical link.

[0075] In the embodiment of the present invention, the user terminal obtains link information, establishes a logical link with the terminal according to the link informa...

Embodiment 2

[0077] The embodiment of the present invention provides a method for obtaining terminal location information. This embodiment is applied to figure 2 The Internet of Things architecture shown, the Internet of Things is composed of the upper Internet and the access layer ad-hoc network, where a central server is set in the Internet, and the ad-hoc network is composed of ad-hoc gateway nodes, data readers and landmark readers . See image 3 , The method includes:

[0078] Step 201: The terminal obtains its own location information;

[0079] Specifically, the location information sent by the landmark reader is received, and the received location information is cached.

[0080] Among them, the terminal can be stationary or moving. Technicians deploy landmark readers in various places in advance, and each landmark reader has its own location information, and each landmark reader can cover a certain range, which is the communication range of the landmark reader.

[0081] Among them, each...

Embodiment 3

[0146] Such as Image 6 As shown, the embodiment of the present invention provides a user terminal, including:

[0147] The obtaining module 301 is configured to obtain link information, where the link information includes at least the identity of the terminal, the identity of the data reader, and the identity of the ad-hoc gateway node;

[0148] The first sending module 302 is configured to establish a logical link with the terminal according to the link information, and send its own identity to the terminal through the established logical link;

[0149] The first receiving module 303 is configured to receive a query response from the established logical link, where the query response carries location information of the terminal.

[0150] Wherein, the obtaining module 301 is specifically configured to search for link information including the terminal's identity from the link information stored in the central server according to the terminal's identity.

[0151] Wherein, if the link in...

Abstract

The invention discloses a method for acquiring the location information of a terminal, a client side, a terminal and a system, which belongs to the field of communication in the Internet of things. The method comprises the following steps: the client side acquires link information, wherein the link information at lease comprises an identify label of the terminal, an identify label of a data reader, and an identify label of an ad-hoc gateway node; the client side creates a logic link with the terminal according to the link information and sends the identify labels to the terminal through the logic link; the terminal receives the identify labels of the client side, fixes the location information of the corresponding accuracy according to the identify labels of the client side, and sends thelocation information to the client side through the logic link. The client side comprises an acquiring module, a first receiving module and a first sending module. The terminal comprises a second receiving module and a second sending module. The system comprises the client side and the terminal. The invention can guarantee the location privacy of the terminal.

Description

Technical field [0001] The present invention relates to the field of Internet of Things communication, in particular to a method, user terminal, terminal and system for obtaining terminal location information. Background technique [0002] The Internet of Things is a network that extends and expands on the basis of the Internet, and the Internet of Things has been widely used. Among them, among the many applications of the Internet of Things, obtaining the location information of the terminal is one of its important applications. [0003] The current method of obtaining the location information of the terminal is: setting up a server in the Internet of Things, the terminal stores its own location information in the server, and updates its current location information in the server every other cycle. When the user needs a terminal When the location information of the terminal is selected, the location information of the terminal is directly searched from the server. [0004] In the ...
