Document Type and Number:
WIPO Patent Application WO/2018/145289
Kind Code:
A1
Abstract:
The present invention relates to the field of wireless communication, and discloses a positioning method and apparatus based on Bluetooth BLE. In the present invention, the positioning method based on Bluetooth BLE is used in a terminal device, and comprises: scanning for a BLE slave device; after finding a target BLE slave device, in at least two positions sequentially acquiring the position Si in which the terminal device is currently located and the distance Ri between the terminal device and the target BLE slave device; and, on the basis of the acquired Si and Ri, calculating the position of the target BLE slave device. Also disclosed in the present invention is a positioning apparatus based on Bluetooth BLE. Compared to the prior art, the present invention enables convenient discovery of the position of a target BLE slave device, greatly reducing the time for searching for a target BLE slave device. Positioning of a target BLE slave device can be implemented without the need to deploy an iBeacon or Bluetooth AP indoors, and there is also no need for complex data processing architecture, thus reducing hardware costs.
