Abstract
A first AP in a wireless network determines that a wireless client device should re-associate from the first AP to a second AP of the wireless network. The first AP communicates an AP coordination message from the first AP to the second AP to share coordination information with the second AP. The first AP coordinates with the second AP to cause the re-association of the wireless client device in accordance with the coordination information. The first and second AP may coordinate directly to synchronize re-association activities. Re-association activities may include the use of a configuration message to the wireless client device, managing transmit power of beacon messages from the first and second APs, or forced disassociation and blocking. The first AP may maintain a record of which re-association activity was successful in causing the wireless client device to re-associate to the second AP.
