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.

Abstract: The present invention relates to methods and apparatus for providing services in high density deployments using dynamic assignment Virtual Local Area Network (VLAN) stacking during client device authentication. An exemplary method includes the steps of: receiving wirelessly, by a first Access Point (AP), a first authentication request message including first user equipment device identification information from a first user equipment device; generating, by the first AP, a second message based on the first authentication request message, the second message including the first user equipment device identification information and location information for the first AP; transmitting, by first AP, the second message to a first server; and receiving in response to the second message, by the first AP, a third message, said third message including dynamically assigned stacked VLAN information including a first Service-VLAN Identifier and a first Customer-VLAN Identifier dynamically assigned to the first user equipment device.

Abstract: The presentation invention relates to methods and apparatus for a mobile device to discover the hidden SSID of a network. An exemplary method embodiment includes the steps of: receiving, at the mobile device, a first beacon frame having a Service Set Identifier (SSID) field set to NULL from a first Access Point; determining, at the mobile device, based on information received from the first Access Point that the mobile device is provisioned to connect to a first network advertised by the first beacon frame; discovering, by the mobile device, a first SSID name for the first network advertised by the first beacon frame for which the mobile device is provisioned. In another embodiment the mobile device associates with the first network after discovering the first SSID name.
