Abstract
Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for caching and sharing client/device keys, session keys, and so on between APs of overlapping wireless networks operated by same or different wireless local areal network (WLAN) operators via one or more Neighbor Key Cache Servers (NKCSs) configured to store client device or session key data for client devices overlapping network boundaries so as to facilitate fast reauthentication between presently serving and target access points (APs) of the same or different WLAN operators. Neighbor reports data may comprise data based on WLAN/SSID from APs associated with each of a plurality of AP home regions and/or realm/Network Access Identifiers from APs associated with an overlapping network of a different WLAN operator.
