摘要： A roaming service method for a fast and secure wireless network is provided. In an embodiment of the present invention, an AP, which an STA associates with, transmits security keys needed for roaming to neighbor APs of the AP. When the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided security key. In another embodiment of the present invention, an authentication server transmits security keys needed for roaming to neighbor APs to which the STA is likely to move, so that when the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided security key.

摘要： The present invention relates to an authentication method for wireless distribution system including at least one base station providing access service to mobile stations in a coverage of the base station. In the authentication method, an unregistered base station receives an authentication request from a mobile station, multicast an identity request for identifying the mobile station over the wireless distribution system, receives identity responses from at least one base station in response to the identity request, and performs authentication of the mobile station on the basis of the identity responses. The distributed authentication method of the present invention is performed without AAA server, when a new base station is installed or isolated base stations are joined, such that it is possible to extend the network in an easy manner without degradation of the security degree and additional labor burden of the operator.

摘要： A method enables access points to support a handoff for at least one station in a wireless network. The wireless network includes the access points for covering constant service areas and the station associated with the one of the access points for receiving communication service. The method comprises generating a neighborhood graph configured by handoff-capable neighboring access points; receiving information including context of a station propagated from a prior access point of the station, the prior access point being one of the neighboring access points; and propagating information including the context corresponding to the station to the neighboring access points of the neighborhood graph in response to association or re-association with the station using the received context.
