Embodiment Construction

[0039] The wireless positioning system is divided into three parts: the positioned device, the positioning information receiving device and the positioning server.

[0040] (1) Device to be positioned: the device to be positioned, that is, any wireless terminal or device that conforms to 802.11 technology. The device to be positioned is characterized by sending wireless signals to the surroundings;

[0041] (2) Positioning information receiving device: an AP that conforms to the standard 802.11 technology. The AP scans the wireless packets of the positioned device and collects the location information of the positioned device. The positioning information includes information such as the MAC address of the positioned device, the signal strength of the positioned device, and the MAC address of the AP. After the AP collects the positioning information of the located device, it sends the positioning information to the AC, and the AC integrates the positioning information sent by ...

Abstract

The invention provides a wireless locating method and apparatus. An AC can determine an AP measurement group used for locating a located device in a locally collected whole network LDB according to the identification information of the located device, and send locating information associated with the located device and corresponding to each AP in the AP measurement group to a locating server, so that the locating server locates the located device through the received locating information. Therefore, by adoption of the wireless locating method and apparatus provided by the invention, the whole network AC shares related locating information collected by the APs in real time, and the locating problem of the located device during movement in a cross-AC area is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a wireless positioning method and device. Background technique [0002] In a wireless network, due to the particularity of its transmission medium, the positioned device can move freely. For the purpose of security, monitoring or location-based services (LBS), it is necessary to accurately locate the located devices in the network based on wireless signals. [0003] The wireless positioning technology realizes the positioning, tracking and monitoring of specific targets by listening to the wireless packets sent by the positioned devices that support the Wi-Fi standard. The AP (Access Point, access point) sends the collected positioning information of the positioned device to the AC (Access Controller, access controller), and the AC integrates the positioning information sent by the AP and reports it to the positioning server. The location calculation is performed...
