Abstract:
1. A method comprising: detecting an impending roam of a wireless client device that receives data communications via a first wireless access point device in a wireless local area network; determining a set of one or more of wireless access point devices other than the first wireless access point device to which the wireless client device may potentially roam; assigning the one or more wireless access point devices in the set to a multicast group; sending the data communications to the multicast group; sending client profile information to each of the wireless access point devices in the set to facilitate set up of communication between the wireless client device and a new wireless access point device; and sending to the new wireless access point device a message containing a synchronized context to enable the new wireless access point device to send stored data to the wireless client device from a point where the first wireless access point device stopped sending data to the wireless client device.
