Embodiment Construction

[0024] A method, device, and wireless access point for sending Bluetooth broadcast frames provided by the embodiments of the present application are applied in a wireless local area network (English: wireless local area network, WLAN), such as figure 1 As shown, it is a schematic structural diagram of a positioning system using Bluetooth. The system includes a wireless access point 101 , a positioning server 102 , two or more than two Bluetooth transmitters 103 and a terminal 104 .

[0025] The Bluetooth transmitter 103 is configured to send a Bluetooth broadcast frame or a Bluetooth broadcast beacon to the terminal 104 . Wherein, the Bluetooth transmitter can be powered by a built-in battery. In the embodiment of the present application, in an indoor scene used for positioning, such as a shopping mall, the number of distributed Bluetooth transmitters is set to be large enough so that the Bluetooth network covers the entire indoor area. Moreover, the WLAN also covers the enti...

Abstract

The invention relates to a method and a device for sending a Bluetooth broadcast frame and a wireless access point. The method comprises the steps of: by the wireless access point, determining the number of WLAN (Wireless Local Area Network) terminals found through a WLAN; according to the number of the WLAN terminals and an interval determining function, determining an interval for sending the Bluetooth broadcast frame, wherein the interval determining function is a monotone decreasing function; and controlling Bluetooth equipment to send the Bluetooth broadcast frame according to the interval. The interval determining function is the monotone decreasing function, i.e., the interval for sending the Bluetooth broadcast frame is monotonously decreased along with increase of the number of the WLAN terminals, and the number of the WLAN terminals is in direct proportion to the number of people, and thus, when a crowd density is increased, time for determining the interval is shortened and positioning accuracy can be ensured; and when the crowd density is reduced, the time for determining the interval is prolonged, i.e., times for sending the broadcast frame in unit time are reduced, so that electric energy is saved, and power consumption of sending equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of Bluetooth positioning, in particular to a method, a device and a wireless access point for sending Bluetooth broadcast frames. Background technique [0002] Bluetooth (English: Bluetooth) positioning is one of the technologies that provide indoor positioning functions. Bluetooth positioning is mainly based on Received Signal Strength Indication (English: Received Signal Strength Indication, also written as Receiver Signal Strength Indicator or Receive Signal Strength Indicator, RSSI). Specifically, in the Bluetooth positioning system, hundreds of thousands of Bluetooth transmitters are distributed, and each Bluetooth transmitter sends a Bluetooth broadcast frame at a fixed frequency. After receiving the broadcast frame, the wireless terminal measures the RSSI of the broadcast frame, and The measured RSSI is sent to the positioning server via another network (for example, a wireless local area network or ...
