Positioning method and device

Abstract

The invention relates to the technical field of communication, particularly relates to a positioning method and device and is used for improving the precision of positioning a position of a terminal. The method comprises the steps that a baseband unit controls N remote radio units to start independently to receive positioning signals sent by the terminal in a power shielding time period of a positioning signal reporting period, so the baseband unit can determine a positioning signal measurement value corresponding to each remote radio unit and further determine the position of the terminal. According to the embodiment of the method and the device, the positioning precision can reach the level of the remote radio units, the positioning precision is improved, and moreover, the power control over the terminal is shielded in the shielding time period, so the power of the terminal is kept the same in the shielding time period, the positioning signals of the terminal is received by each remote radio unit under the same condition, and the positioning precision of the position of the terminal is further 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 the mobile communication network is developing rapidly, and the application based on positioning technology is booming, and has penetrated into all aspects of social life, such as navigation services, location push, associated search, and big data behavior. Currently, positioning technology is based on proximity The positioning technology is that the terminal receives the signal of the reference source, and regards the location of the reference source with the strongest received signal power as the location of the mobile terminal, so as to realize positioning. Due to the simple implementation method of this positioning technology, it is widely used. [0003] The positioning technology based on the proximity relationship still has the problem of i...

Problems solved by technology

[0003] The positioning technology based on the proximity relationship still has the problem of inaccurate positioning in the application scenario of the new indoor distribution system. The reason is that for the new indoor distribution system, a cell is covered by multiple radio remote units to increase the coverage area of ​​the cell. , and the positioning signals between multiple remote radio units are superimposed and sent back to the baseband unit for demodulation. In this way, the source of the signal cannot be identified due to the superposition of the positioning signals, so the location of the specific remote radio unit cannot be located.

[0004] Therefore, the current positioning technology based on the proximity relationship has the problem of low positioning accuracy.
