    Abstract: Network information may be discoverable without requiring a connection to that network. For example, Access Network Query Protocol (“ANQP”) may allow a device to discover information about a network prior to the device associating with that network. In other words, ANQP allows a network terminal to request additional network information prior to establishing network capability. The additional network information that may be discoverable includes network latency, cellular capabilities, hotspot capabilities, mobility capabilities, neighbor reports, station identification, and multiple hotspot session identification.

    Abstract: A bridge communicates a link layer frame between a device and a cellular access network node, the link layer frame comprising a portion including a header and data of an upper layer protocol layer instance in the device or the cellular access network node. The header includes identification information to identify which of a plurality of upper layer protocol layer instances the data is associated with.

    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.

    Abstract translation: 移动设备可以无缝地在扩展服务集（“ESS”）网络之间转换，使得尽管转换，消费者也不会丢失网络连接。 用于启用转换的通信可以在与该网络相关联之前。 可以通过创建和利用在预关联状态下向移动设备通告其身份的中央密钥持有者权限来实现无缝转换。 移动设备可以使用密钥发现通信以及密钥生成方法来认证和/或与网络相关联并且从一个ESS转换到另一个ESS。 跨ESS可能有一个共同的根密钥。 在移动设备遇到的每个新接入点（“AP”）处，可以通过发现通信发现ESS和密钥持有者身份。
