Problems solved by technology

However, occasionally a Wi-Fi AP may be relocated to a new location due to, for example, a building, office, or home relocation
If the new location of the migrated Wi-Fi AP is not updated in time in the database, the terminal devices connected to the migrated Wi-Fi AP may still depend on the old location of the Wi-Fi AP, which may lead to positioning errors
For example, a Wi-Fi AP may have recently migrated from Boston to New York City, and if the database is not updated in time, the migration may cause end devices connected to the Wi-Fi AP to be incorrectly located in Boston

Embodiment Construction

[0013] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0014] The present application generally relates to methods and apparatus for detecting a change in location of a Wi-Fi AP. In some embodiments, the method may include scanning for access stations around the terminal device. The method may also include obtaining a list of scanned access stations. End devices can connect to access points in the list of scanned access stations. The method may further include detecting a change in location of the connected access point when the list of scanned access stations does not include the reference access station. The access point may be associated with a reference access station.

[0015] In some embodiments, an association between a scanning access station and a reference access...

Abstract

The present disclosure relates to a method and apparatus for detecting position change of an access point. According to certain embodiments, the method includes: obtaining a list of access stations scanned by a terminal device, wherein the list of scanned access stations includes the access point; and detecting the position change of the access point when the list of scanned access stations does not include a reference access station in association with the access point.

Description

technical field [0001] The present application relates to positioning technology, and more particularly, to a method and device for detecting changes in the location of an access point. Background technique [0002] A Wi-Fi terminal device can obtain its own location by referring to the location of a Wi-Fi access point (AP) to which it is connected. For example, a smartphone can obtain its location by referring to the location of the Wi-Fi AP to which the smartphone is currently connected. A smartphone can query the location of a connected Wi-Fi AP by sending the Wi-Fi AP's Media Access Control (MAC) address to a Wi-Fi AP location server. The Wi-Fi AP location server may include a database of Wi-Fi AP locations that contains a correspondence between the Wi-Fi AP's MAC address and its Global Positioning System (GPS) location, and returns information to the smartphone related to the connected Wi-Fi AP location. The GPS location corresponding to the MAC address of the Fi AP. ...
