KEY CACHING, QOS AND MULTICAST EXTENSIONS TO MEDIA-INDEPENDENT PRE-AUTHENTICATION

摘要

This present application relates to, among other things, Key Caching, QoS and Multicast extensions and improvements to the Media-independent Pre-Auth entication (MPA) framework, a new handover optimization mechanism that has a potential to address issues on existing mobility management protocols and m obility optimization mechanisms. MPA is a mobile assisted, secure handover o ptimization scheme that works over any link-layer and with any mobility mana gement protocol.
