Abstract:
Transitioning voice clients among network resources. A network monitor using IEEE 802.11e QBSS Load IE elements monitors the load on one or more wireless access points. When the load on an access point, as reported in the QBSS Load Element IE exceeds a predetermined threshold, the network monitor sends a message to that AP which causes the AP to send BSS Transition Management Request frames to all connected voice clients which are currently idle. The information passed to the AP and then to the client may include one or more neighboring APs with capacity.
