Abstract:
A mobile device may transition between Extended Service Set (“ESS”) networks seamlessly, such that a consumer never loses the network connection despite the transition. The communication for enabling a transition may be prior to association with that network. The seamless transition may be enabled through the creation and utilization of a central key holder authority that advertises its identity to mobile devices in a pre-associated state. The mobile device can use the key discovery communication along with a key generation method to authenticate and/or associate with a network and transition from one ESS to another. There may be a common root key across ESSs. At each new access point (“AP”) that the mobile device encounters, ESS and key holder identities may be discovered through discovery communications.
