Problems solved by technology

[0006] The positioning scheme based on RSSI requires a lot of time for field testing due to the need for field testing, which increases the complexity of positioning work
[0007] For the positioning scheme based on AOA, due to the complex wireless channel conditions in the indoor communication environment, the smart antenna often cannot accurately identify the beam direction, or the estimated direction does not match the actual position of the user, resulting in low positioning accuracy, or even unavailable

specific Embodiment 1

[0066] In this specific example one, as figure 2 As shown, the corresponding positioning process may specifically include:

[0067] Step 21, the network entity (collectively referred to as the positioning entity) used to perform the positioning operation obtains the network map information obtained during the system initialization process, and each AP to the terminal to be positioned (also can be other entities to be positioned, such as an illegal network element, etc., The terminals to be located mentioned below are all specific application examples, that is, the corresponding terminals can be replaced by the communication beam RSSI of other entities to be located) and the direction information of the corresponding beams, and the corresponding network map information includes AP information in the network, and Obstacle information, etc.;

[0068] The corresponding collectively referred to as the positioning entity can be an AP, or it can also be a network element such as a ...

specific Embodiment 2

[0094] In this specific embodiment 2, the difference from the specific embodiment 1 is that: the optimal communication beam of the anchor node and its adjacent beams are used to determine the implementation scheme of the communication beam between each anchor node and the entity to be positioned, so as to improve the positioning accuracy.

[0095] Such as Figure 5 As shown, the corresponding positioning process may include:

[0096] Step 51, the positioning entity obtains the network map information, and the optimal communication beam from each AP to the terminal to be located, the RSSI of the adjacent beam and the direction information of the corresponding beam;

[0097] Specifically, if the positioning entity is a terminal, the terminal sends a positioning request, and each AP that receives the request sends the beam information communicated with the terminal to the terminal, and the terminal simultaneously counts the RSSI information of the corresponding beam, and then th...

specific Embodiment 3

[0112] In this specific embodiment three, after the grid point set of the possible position of the terminal is determined according to the beam information of the determined trusted anchor node group in the specific embodiment 1 and the specific embodiment 2, the grid point sets that are not in the grid point set May be mesh point removal where the entity to be located is located.

[0113] Such as Figure 7 As shown, the positioning processing process provided in the third embodiment may include:

[0114] The processing procedure performed in steps 71 to 73 is the same as the processing procedure performed in steps 21 to 23 in the first embodiment, or the same as the processing procedure performed in steps 51 to 54 in the second embodiment, so here No longer described in detail.

[0115] Step 74: In the determined trusted anchor node groups, obtain the beam overlapping areas of each trusted anchor node group according to the beam information of each anchor node group, and re...

Abstract

The invention provides a method and a device for positioning an entity. The method comprises the following steps of: determining a plurality of anchor node groups according to wave beam direction information of anchor nodes and obstacle information in a network; and determining mesh points included in wave beam overlapped areas corresponding to the plurality of credible anchor node groups and determining the actual position of the entity to be positioned according to the included mesh points. The implementation scheme that the entity to be positioned is positioned by combining the wave beam direction information of the nodes according to the anchor node and obstacle information in a communication network is adopted by the embodiment of the invention, so that the entity to be positioned can be positioned conveniently and accurately.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a positioning technology in a communication system. Background technique [0002] At present, the positioning methods commonly used in wireless communication networks are mainly implemented based on RSSI (Received Signal Strength Indication) or AOA (Angle of Arrival). [0003] Correspondingly, adopting the RSSI-based positioning scheme is to establish a corresponding relationship between RSSI (or the statistical distribution of RSSI) and a geographical location according to field tests, and then use the established corresponding relationship to locate the terminal. [0004] The corresponding positioning scheme based on AOA uses multiple Land stations (ground stations) with known positions for positioning. The corresponding Land station has an antenna system that can perform AOA estimation. Specifically, the position of the terminal can be determined according to the esti...
