摘要： Persistent communication layer credentials generated on a persistent communication layer at one network may be leveraged to perform authentication on another. For example, the persistent communication layer credentials may include application-layer credentials derived on an application layer. The application-layer credentials may be used to establish authentication credentials for authenticating a mobile device for access to services at a network server. The authentication credentials may be derived from the application-layer credentials of another network to enable a seamless handoff from one network to another. The authentication credentials may be derived from the application-layer credentials using reverse bootstrapping or other key derivation functions. The mobile device and/or network entity to which the mobile device is being authenticated may enable communication of authentication information between the communication layers to enable authentication of a device using multiple communication layers.

摘要： A method performed by a STA may comprise receiving a frame, from a first AP including an indication of a configuration change counter (CCC) associated with a second AP. The CCC may be an unsigned integer that increments when an update to one or more AP parameters of the second AP has occurred. The method may further comprise establishing a first wireless link with the first AP and establishing a master key via at least the first wireless link.

摘要： A method performed by an AP may comprise initializing a CCC and increasing the CCC upon a change of at least one of a plurality of parameters of the AP. The plurality of parameters may include at least a high throughput (HT) Operation element, one or more Enhanced Distributed Channel Access (EDCA) parameters, or one or more operational mode parameters. The method may further comprise transmitting a frame, to at least one STA, wherein the frame includes an indication of the CCC, and the frame indicates that the at least one STA return from a power saving mode.

摘要： A power saving method performed by a STA may comprise receiving, from an AP, a first beacon comprising a CCC value. The CCC value may be an integer value that represents a configuration instance of the AP. The STA may return from a power saving mode upon receiving the first beacon and receive a second beacon from the AP. The second beacon may be a primary beacon of the AP. The first beacon may comprise an SSID of the AP. The STA may perform an association procedure with the AP upon receiving the first beacon.

摘要： An application server receives a request for service from a wireless transmit/receive unit (WTRU) associated with a home network that includes a home subscriber server (HSS) and a bootstrapping server function (BSF) coupled via a Zh reference point. The application server authenticates the WTRU at least in part by (i) redirecting the WTRU to an identity provider co-located with a network application function (IDP/NAF) and coupled to the BSF via a Zn reference point and (ii) receiving an assertion from the WTRU that the IDP/NAF has authenticated the WTRU based on user security settings retrieved from the BSF by the IDP/NAF over the Zn reference point. After authenticating the WTRU, the application server (i) retrieves user-specific Sh-reference-point-type data from the HSS via the IDP/NAF over the Zn and Zh reference points and (ii) provides the service to the WTRU based on the retrieved user-specific Sh-reference-point-type data.

摘要： A methods and apparatus may be used for accelerated link setup. A method may include a station (STA) acquiring information about an access point of an Institute of Electrical and Electronics Engineers (IEEE) 802.11 network in advance through a previously connected IEEE 802.11 interface and/or an interface other than the IEEE 802.11 network. The STA may use the acquired information during a link setup procedure between the STA and the access point. The information may include a suggestion for a specific procedure to complete the link setup procedure between the STA and the access point.
