HANDSOFFS BETWEEN ACCESS POINTS IN A WI-FI ENVIRONMENT

摘要

Techniques disclosed herein include systems and methods for providing active mobility of Wi-Fi enabled devices within a given wireless local area network (WLAN). In general, techniques include dynamically commanding Wi-Fi enabled devices to disconnect from a corresponding access point in response to meeting predetermined conditions. A forced disconnect can be based on various criteria such as low-power or lost packet thresholds triggering the forced disconnect. Such techniques cause a Wi-Fi enabled device to disconnect from one access point and connect to another access point before a connection quality deteriorates to a point that causes noticeable interruptions in connectivity or a generally poor experience, thereby enabling a smooth transition among access points.

1. A method comprising:
establishing a wireless link between a client device and a first access point over a radio frequency communication channel, the wireless link conveying data between the client device and the first access point; monitoring connection quality of the wireless link between the client device and the first access point; and in response to detecting that the connection quality of the wireless link deteriorates, transmitting a disassociate message from the first access point to the client device, the disassociate message terminating the wireless link.
