Problems solved by technology
[0008] In the development process of the positioning technology based on the proximity relationship, although the multi-CELL ID cooperative positioning method or the remote cell-level positioning method can improve the positioning accuracy, however, since the positioning process is calculated based on the power field strength, in practical applications, there are often Therefore, the positioning method based on the proximity relationship may easily lead to misjudgment of floors in the positioning results, which will lead to serious deviations in the positioning results and affect the application. However, there is no corresponding solution in the industry at present.

Embodiment Construction
[0047] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0048] Such as figure 1 As shown, it is an application scenario applicable to the embodiment of the present invention. Wherein, there are multiple floors in a building, and one or more access points are distributed on each floor, where the access points can be nodes such as remote radio units and routers, figure 1 The floor node distribution structure is given as an example, that is, there are 4 floors in total, and each floor includes...

The invention belongs to the communication technical field and relates to a positioning method and device. The positioning method and device of the invention aim to improve the accuracy of the positioning of a floor where a terminal is located. The positioning method includes the following steps that: reported measurement information is received, wherein the measurement information contains the identifier of the terminal, the identifiers of access points which are in measurement relations with the terminal, signal to noise ratio values corresponding to the identifiers of the access points, the attribute information of the access points, wherein the attribute information of each access point includes the information of a floor where the access point is located; a comprehensive signal to noise ratio value corresponding to each floor is determined according to the information of the floor where the access point is located, and the signal to noise ratio value corresponding to the identifier of each access point; and a floor with the maximum comprehensive signal to noise ratio value is determined as a floor where the terminal is located. According to the positioning method and device provided by the embodiments of the invention, the comprehensive signal to noise ratio value of each floor is determined, the floor where the terminal is located can be determined accurately, the accuracy of the positioning of the floor where the terminal is located can be improved.
Description
technical field [0001] The present invention relates to the field of communication technologies, in particular to a positioning method and device. Background technique [0002] At present, the positioning technology of terminals in mobile communication networks has attracted more and more people's attention. The application of location-based services has flourished and penetrated into all aspects of social life, such as navigation services, location push and associated search, and big data behavior. In this era, various information services derived from location information will shine, which will further highlight the importance of positioning technology. [0003] The positioning technology can be divided into three categories from the method: the positioning technology based on the triangular relationship, the positioning technology based on the scene analysis, and the positioning technology based on the proximity relationship. Among them, the positioning technology of pro...
